Hawker Evolution ATEX certified batteries are valve-regulated, maintenance free batteries. Unlike conventional batteries with liquid electrolyte they have immobilised electrolyte (gelled sulphuric acid). Instead of a vent plug, a valve is used to regulate the internal gas pressure, preventing the ingress of oxygen from the air and allowing the escape of excess charging gasses. When operating valve-regulated lead-acid batteries the same safety requirements as for vented cells apply, to protect against hazards from electric current, from explosion of electrolytic gas and – with some limitations – from the corrosive electrolyte. Hawker Evolution ATEX battery valves should never be removed. These batteries do not require topping-up with distilled or demineralized water. Hawker Evolution ATEX certified batteries are designed for max. 4 years of use.

Ignoring the operation instructions, repair with non-original parts or using additives for the electrolyte will render the warranty void. All the failures,malfunctions or defects of the battery, charger any other accessories, must be notified to our After Sales Service.
Safety
Always remember that the battery is a source of power, even when fully
discharged there remains sufficient energy in the battery to cause serious
damage.
Follow these safety codes
- Never charge a Ex battery in the zoned controlled area.
- Never disconnect the battery in a zoned area. Isolate circuits before disconnecting the battery outside a zoned area.
- Never open the battery cover in a zoned area.
- Always use certified DC plugs for connection to the battery.
- Never use the battery if damaged or bare cables are evident.
- Never use the battery if the DC plugs are damaged.
- Never attempt to service the battery: Call your recommended authorised service centre.
Service
Your local authorised service engineer provides local help and support. This handbook gives guidelines of a general nature; our engineer will help you to interpret your needs in relationship to your particular requirements. Your authorised engineer can answer the questions that are beyond the scope of this manual and obtain specialist help should it be required. Your battery is an expensive investment and designed for use in a zoned area, it is our aim to help you obtain the best possible results from it. Please do not hesitate to call your local service centre if you have any questions relating to the battery.
Handling
Lead acid Ex batteries are very heavy. Always use approved moving equipment when attempting to change batteries When lifting and handling the Ex batteries use the correct approved lifting equipment and keep the battery in and up right position. Due to the wide variation in types of electric vehicles, designs of battery containers, equipment used and methods of battery changing, it is not possible to give detailed instructions on the procedures to be followed when changing the batteries on an electric vehicle. The manufacturer of the vehicle or the battery changing equipment must supply the correct method and procedure.
Taking delivery of your battery
Do not carry out any of the following procedures in a zoned area. Use special coding systems for maintenance free batteries for the charging plug- and- socket devices to prevent accidental connection to a wrong type of charger. The possibility of the battery being connected in the wrong polarity is prevented by visibly marking the polarities adjacent to the connection plug with an identification colour (Positive Red and Negative Blue). The possibility of the insulation on the overall battery voltage leads being cut to expose the conductor is prevented by sleeving the insulation with cable retention (i.e. spiral wrap). Remove all packing material and carefully examine the containers, etc. to ensure that there is no physical damage If the battery is not used at receipt, please refer to (16) storage.
Commissioning
The charger cables must be connected to ensure a good contact, taking care that the polarity is correct. Otherwise battery, vehicle or charger could be damaged Wipe over the tops and sides of the cells and container with a damp cloth to remove dust, water. Cell cleanliness can not be too highly stressed. Check that all connections are tight. The specified torque loading for the pole screws is 25 +2Nm (screw M10). Make sure that the cells are readily accessible for testing. This will make regular maintenance hassle free. Check that the battery compartment is well drained and ventilated and that there is no risk of metal objects dropping through the top ventilation of the battery. Check that the battery sits quite firmly and securely in its housing, use suitable packing to prevent any movement when the vehicle is in motion. The cables should be flexible and of sufficient length to prevent any strain being imposed either on the cable or the certified terminals to which the cables are connected. If a new Ex battery is to be used in an application where there is uncertainty about the zoned area please contact your local factory inspector. Never directly connect an electrical appliance (for example: warning beacon) to some cells of the battery. This could lead to an imbalance of the cells during the recharge, i.e. a loss of capacity, the risk of insufficient discharge time, damage to the cells and this may EFFECT THE WARRANTY OF THE BATTERY. The battery is then charged as in item (8).
Recommended maintenance
The electrolyte is immobilised in a gel. The density of the electrolyte cannot be measured.
-
Never refill with water!
-
Never remove the safety valve from the cell In case of accidental damage of the valve, contact our After Sales Service for replacement.
(I) Every day:
Recharge the battery after discharge. -
Remember never charge an Ex battery in a zoned areaeven if approved charging equipment is available. Always check that the charger is operating correctly.
-
Check that the plugs and sockets are in good condition.
(II) Weekly:
Check all connections and take off leads for any frayed or worn insulation. If
frayed wires or worn insulation is noted take the battery out of service
immediately and place in a safe area that is outside the zoned area. DO NOT
ATTEMPT TO REPAIR an Ex battery. Call your local service depot Check that all
insulators and vent plugs are in place and that the battery plugs are of
sound condition.
Ensure that the top of the battery is clean and dry. Dirt and moisture can
provide tracking paths for the electricity and potentially cause a spark in a
zoned area. Should there be any corrosion of the metal container, scrape this
off and neutralise the area with a solution of water and baking soda, or
diluted ammonia, and protect the part from further corrosion by painting it
with acid proof paint
(III) Monthly:
-
Carry out end of charge voltage readings at C5/100, measure and record:
-
the voltage of the battery
-
the voltages of each cell
If significant changes from earlier measurements or differences between the cells or bloc batteries are found, please contact EnerSys®
Service. -
If the discharge time of the battery is not sufficient, check:
-
That the work required is compatible with the battery capacity
-
The settings of the charger
-
The settings of the discharge limiter.
(IV) Annually:
Check with attention:
- the state of the plugs :be sure to have a good contact between the plugs without trace of overheating.
• the state of the output cables. If you check the torque loading, you must use a torque wrench with respect of recommended value : 25+2 Nm
In accordance with EN 1175-1 at least once per year, the insulation resistance of the truck and the battery must be checked by an electrical specialist. The tests on the nsulation resistance of the battery must be conducted in accordance with EN 1987 part1. The insulation resistance of the battery thus determined must not be below a value of 50 Ω per Volt of nominal voltage, in compliance with EN 62485-3. For batteries up to 120 V nominal voltage the minimum value is 1000 Ω.
Discharge
Ventilation openings must not be sealed or covered. Electrical connections (e.g. plugs) must only be connected or disconnected in the open circuit condition. To achieve the optimum life for the battery, operating discharges of more than 80 % of the rated capacity must be avoided (deep discharge). They reduce the battery service life. To measure the state of discharge use only the battery manufacturer’s recommended discharge indicators (imperative presence of a discharge limiter with an energy cut-off at 1.83 vpc operating voltage at 80% DOD C5, when the recharging time is 12 hours, and 1.87 vpc at 60 % DOD C5 when the recharging time is 8 hours). Discharged batteries must be recharged and never be left in a discharged state for a long time. Hawker ® Evolution ATEX certified batteries can be used in normal duty applications one cycle per day at a max. DOD 80% C5 and a maximum 6 days per week. Avoid applications where:
- no rest time is available allowing the battery to cool
- battery duty leads to a high increase of temperature during operation.
It is recommended that the battery is discharged evenly and the use of tappings across a part of the battery is discouraged. To overcome this problem a D.C.- D.C. converter must be used to allow auxiliary loads to be supplied from the whole battery. NOTE: The D.C.-D.C. converter must be certified for use in a zoned area as well as the auxiliary equipment. Battery performance is directly related to temperature. Batteries are rated at 30ºC. Where the battery temperature is lower than this, the available performance is reduced. Additional capacity is therefore required when the batteries are to be used in areas of low ambient temperatures (e.g. cold stores).
Recharge
NOTE: NEVER RECHARGE A Ex BATTERY IN A ZONED AREA.
A full charge shall be carried out every working day with a Hawker charger.
The charging time for a 80 % discharged battery shall be 12 hours, or 8 hours
for a 60% discharged battery with the appropriately assigned Hawker high
frequency charger. After any changing of cables on the charger, our
technician must visit the site to check the charger.
Hawker Evolution ATEX certified batteries have a low gas emission.
Nevertheless, when charging, proper provision shall be made for venting of the
charging gases (EN 62485-3).
Battery container lids and the covers of battery compartments shall be opened
or removed. With the charger switched off connect the battery, ensuring that
the polarity is correct.
(Positive to positive, negative to negative). Now switch on the charger.
If the charger was not purchased together with the battery it is best to have
its suitability checked by the manufacturers service department. When
charging, proper provision must be made for venting of the charging gases.
PzV batteries (Hawker Evolution ATEX certified batteries) are low gas
emission, so some charging gasses are evolved.
Battery container lids and the covers of battery compartments must be opened
or removed.
During the charge the battery must be removed from the closed battery
compartment on the truck. The ventilation must comply to EN 62485-3 standard.
The length of the D.C. cable between the charger and battery affects the
voltage drop back to the control unit of the charger.
The cable should not be extended without prior consultation with the charger
manufacturer and supplier of your Ex battery.
In situations where the battery is generally only very lightly discharged, it
may be an option to recharge the battery at less frequent intervals, perhaps
every second day. In such circumstances please seek the advice or your local
service engineer.
Do not disconnect battery until the charger has been switched off.
Your local area service centre must approve any managing charging system
otherwise the warranty may be invalidated.
Equalizing
Equalising charges are used to optimise the life of the battery and to
maintain its capacity. A unique equalisation charge is automatically carried
out weekly 8 hours after the end of the charge with a Hawker HF charger.
But remember never charge an Ex battery in a zoned area at any time.
Temperature
The temperature range of use for the battery is between +5°C and + 35 °C. Any
use outside of this range shall be approved by a EnerSys service technician.
Optimal battery life is obtained for a battery temperature of 25-30°C High
temperatures reduce battery life according to IEC 1431 technical report, lower
temperatures reduce the capacity available.
The temperature on surface must never exceed 80°C in explosive area. If
electrolyte temperature reaches 55°C during the charge, wait for the cooling
before to use the battery in the explosive area. If a hot battery is detected
it should be taken out of the controlled zoned area and allowed to cool to
ambient temperature. An investigation should be carried out into why the
battery is getting hot before it is placed back into service.
Possible reasons why the battery might be getting hot is that there might be a
fault in the equipment that the battery is powering or a fault could have
occurred within the cells of the battery. In the case of a suspected battery
problem contact your local service centre.
Surrounding area conditions
The apparatus is designed to cope with the intended surrounding area
conditions.
Effect of explosive atmosphere on materials
The materials selected are not known to react with any explosive
atmospheres to which the apparatus may be subjected
Protection against other hazards
The apparatus does not cause injury or harm when used as specified in the
installation and operation manual.
Hazards arising from different ignition sources
The apparatus does not produce ignition capable electrical sparks or arcs. The
apparatus has also been designed not to produce potential ignition sources
from electromagnetic, acoustic, optical or other such external energy
sources.
Withstanding attack by aggressive substances
The individual cells contains sulphuric acid: These cells and enclosure which
make up the apparatus are constructed from materials that are resistant to
acid attack see manufactures data sheet.
Care of the battery
The battery should always be kept clean and dry to prevent tracking currents :
wipe over the tops and sides of the cells and container with a damp cloth to
remove dust, water.. Any liquid in the battery tray must be extracted and
disposed of in the prescribed manner. Damage to the insulation of the tray
should be repaired after cleaning, to ensure that the insulation value
complies with EN 62485-3 and to prevent tray corrosion.
If it is necessary to remove cells it is best to call in our service
department for this.
Storage
If batteries are taken out of service for a lengthy period they should be
stored, disconnected from the truck, in the fully charged condition in a dry,
frost-free room. Batteries shall be recharged after a maximum storage time of
:
• 2 months at 30°C
• 3 months at 20°C
Effect a recharge before putting the battery into service. A monthly
refreshing charge is recommended. The storage time should be taken into
account when considering the life of the battery. Never leave a battery
connected to a truck for a long time. Storage at open circuit is not allowed
when in discharged state.
Malfunctions
If malfunctions are found on the battery or the charger our service department should be called in without delay. The measurements taken in point III (6) will facilitate fault finding and their elimination. A service contract with us will make it easier to detect and correct faults in good time.
Disposal and back to the manufacturer!
Always dispose of the battery container and cells through your local service
depot. Do not attempt to dismantle the battery or the cells in any way. Once
the product has failed and is no longer repairable store outside the Zoned
area until removed for reclaim.
Batteries with this sign must be recycled.
Batteries which are not returned for the recycling process must be disposed of
as hazardous waste!
When using motive power batteries and chargers, the operator must comply with
the current standards, laws,rules, and regulations in force in the country of
use!
