WARNING AND SECURITY RULES

Imperative charge after all deep discharge
Damage not covered under warranty

Familiarize personnel with battery installation, charging and maintenance procedures. Display operating instructions visibly near the battery system. Restrict access to battery area, permitting only trained personnel, to reduce the possibility of injury.
Batteries are extremely heavy. Exercise care when handling batteries. When lifting use appropriate mechanical equipment to safely handle batteries and avoid injury to personnel.
Prohibit smoking. Keep away flames and sparks of all kinds from the vicinity of storage batteries as liberated or entrapped hydrogen gas in the cells may be exploded, causing injury to personnel and/or damage to cells.
Wear rubber apron, gloves and safety goggles (or face shield) when handling, installing, or working on batteries. This will help to prevent injury due to splashing or spillage of sulfuric acid. Observe all accident prevention rules.
Wash all acid splashes in eyes or on skin with plenty of clean water and seek immediate medical assistance. Acid splashes on clothing should be washed out with water. Acid on skin or clothing should also be immediately neutralized with a solution of baking soda and water.
Electrolyte is highly corrosive. Promptly neutralize and remove any electrolyte spilled when handling or installing cells. Use a baking soda/water solution (1 lb. per gallon of water) to prevent possible injury to personnel.
Explosion and fire risk. Avoid short-circuits. Never place metal tools on top of cells since sparks due to shorting across cell terminals may result in an explosion of hydrogen gas in or near the cells. Insulate tool handles to protect against shorting. Prior to making contact with the cell, discharge static electricity by touching a grounded surface.
Dangerous voltage. Whenever possible, when making repairs to charging equipment and/or batteries, interrupt AC & DC circuits to reduce the possibility of injury to personnel and damage to system equipment. This is particularly important with high voltage systems (110 volts and above).
Recycle and Dispose of Used Batteries
Used batteries contain valuable recyclable materials. They must NOT be disposed of with domestic waste. Modes of return and recycling shall conform to the prevailing regulations in operation at the site where the battery system is located.

Dear customer, thank you for purchasing one of our Uniteck products. Please read all the instructions carefully and thoroughly before using the product.

DESCRIPTION

UNIBAT is a lead-acid battery with a VRLA technology and an AGM carbon technology.
Equipped with an advanced technological design (compressed high density pure lead grid, highly absorbent glass mat, carbon additive…), UNIBAT AGM batteries perform up to 2 times better in cycling and lifespan than most batteries of the same category on the market.
Thanks to their unique internal design, UNIBAT AGM batteries can accept discharge rates of up to 80% to use the maximum of the available energy. Their weak self-discharge guarantees a good stability over time.
Its AGM technology guarantees safe use, without leaks or gas release.
VRLA = Valve regulated Lead Acid

PRECAUTIONS BEFORE INSTALLATION

Ventilation
Valve Regulated Lead-acid batteries produce hydrogen and oxygen during their functioning.
These gases result from electrolysis of the water portion of the electrolyte by the charging current. Natural or artificial ventilation is recommended in the battery room, or area, to prevent build-up. Concentrations above 4% can result in an explosive mixture, which could be ignited by sparks from adjacent electrical equipment as well as sparks or open flame introduced by personnel. All air moved by ventilation should be exhausted into the outside atmosphere and should not be allowed to re-circulate into other confined areas. Ventilation requirements vary. Contact your local authority for requirements.

Storage location
A battery system should be installed in a clean, fresh (between 20°C and 25°C) and dry location.
Avoid placing the battery in a warm area or in direct sunlight. Heaters, radiators and steam pipes can cause serious electrolyte temperature variation among cells within a battery system. The layout and contents of a battery room must comply with all local standards and allow easy access to the batteries.

Handling
Batteries are supplied in a fully charged state and must be unpacked carefully to avoid short-circuit between terminals of opposite polarity. The cells are heavy and must be lifted with appropriate equipment. Avoid lifting batteries by the terminal posts. Batteries should be lifted from bottom of jars or with available lifting straps. At all times exercise caution when handling batteries to prevent damage of the plastic containers.

Tools
Use tools with insulated handles. Do not place or drop metal objects onto the battery. Remove rings, wristwatch, and metal articles of clothing which may come into contact with the battery terminals.

Removal
Before removing old batteries, ensure that all electric loads are switched off (breakers, fuses, and switches). Batteries must be packaged, shipped and recycled in accordance with the regulations.

Operating temperature
All technical data are measured with an ambient temperature of 25°C.
High ambient temperatures reduce the lifespan of batteries. On the contrary, weak temperatures reduce available capacity.
Thus, in order to make the most of Unbait batteries performances (number of cycling, lifespan, available capacity), you need to use it in an environment with a temperature between 20°C and 25°C.

WIRING

Wiring connection series / parallel
For the coupling, proceed as below:

NB : Cables resistors in every chain need to be the same (same section, same length).

Some advice:

• For the parallel wiring, use the diagonal wiring for standardization of charging/discharging, with a maximum of 4 parallel chains.

• Do not couple batteries of different ages and different technologies.

• If there is the same capacity, prefer one powerful battery than 2 small batteries connected in parallel.

• Spread a thin layer of contact lubricant on terminals and on roll thread. Avoid all contact with the battery box.

Distance inter-batteries
When they are functioning batteries produce heat. In order to reduce those effects on performances, it is recommended not to stick batteries together. Make sure you have at least from 0.5 to 2cm between each battery.

Tightening
Tighten terminals screws according to the tightening torque mentioned below:
23.5~25.5 Nm or 240-260 Kgf-cm
A wrong tightening can interfere with your charger or your charging system. It means that it can create irregular performances and/or damage your battery. Once all bolts are well tightened, put the isolator cap to protect against all accidental contacts.

WARNING BEFORE USING

Initial capacity
As all lead-acid batteries, after production, UNIBAT battery does not offer its full storage capacity (initial capacity 90-100%). Its full capacity will be reached only after a few cycles of full charging (it depends on the using frequency during the first 6 months).

Imperative charging after deep discharging

Be careful, it is hardly recommended not to leave a lead-acid battery in deep discharge state more than 24h. To avoid damaging your battery in an irreversible way you absolutely need to recharge it at 100%.

Overcharge prohibited

The charge does not have to exceed 15V. An overcharge can damage in an irreversible way the battery and cancel the warranty.

Maintenance free battery

UNIBAT batteries have VRLA technology (Valve Regulated Lead acid). There is no need to add liquid, that is the main difference with liquid lead batteries. UNIBAT batteries are completely hermetic. If you open the battery you cancel the warranty.

Bubble and/or crackling during charging

Crackling or bubbles is a common phenomenon on all technologies for lead batteries (Liquid, AGM, GEL).
It is caused by the current going from the electrolyte of positive plate to negative plate. It often appears at 13.8V, and it is intensified by the current and/or by some charging curves with throb charging steps.
This noise is more intense during the first charges, it is when the battery increases its capacity. It can be softened with time.
Warning: the same phenomenon can also come from a charging issue. It is the case when the noise is present with tensions higher than 15.5V. It is a problem from voltage regulation or too powerful charge from your charging system (alternator/battery charger, solar…). If it happens, disconnect your charging system and make appropriate corrections.

CHARGING STEPS

In order to completely enjoy UNIBAT batteries storage capacity and power performance, it is recommended to charge at least in 3 steps: bulk/boost (main charge), absorption (equalization), float.

Bulk/boost Current (A) = 25% of the capacity (max 40%)

| A constant current of 25% of the capacity is recommended until the equalization voltage is reached. At the end of this step, the battery is charged at 80- 90%.
---|---

Absorption / Equalization Charging current (A) = 20% of the capacity Charging voltage = 14,4V (accepted: 14,1-14,7V)

| The voltage of the battery reaches its equalization voltage and it is stabilized. The current is reducing.

Floating / maintenance charging Current (A) = 0,5% of the capacity End of charging voltage = – with charger = 13,2V-13,7V – with Solar = 13,6-13,9V

| The battery is charged. Charging voltage is reduced and a low current must be delivered in order to offset the battery self-discharge.

Those 3 steps are minimum steps you need to follow in order to ensure a 100% charge for an occasional use. For regular and intensive charge, it is recommended using multi-steps evolved chargers (cf UNICHARGE chargers or UNIMPPT charge controller). Thanks to it you can completely enjoy your batteries performances (cycling number, lifespan)

Threshold voltage adjustment according to ambient temperature

Charging voltage data are indicated for an ambient temperature of 25°C. Below this temperature it is recommended to adjust voltage threshold at +/- 30mV per degree.
Ex.: Ambient temperature of 35°C = 35°C – 25°C x 0,003V = voltage must be reduced by 0.03V.

CHARGING STATUS CHECK

Checking voltage during rest

Open circuit voltage (OCV) varies according to ambient temperature and remaining capacity of the battery. In general, open circuit voltage is determined by the specific gravity of the electrolyte. Open circuit voltage is the voltage of an accumulator which is without external consumers (not under load).
The measurement of the open circuit voltage needs to be taken either 24 hours after a full charge, or at least 10 minutes after discharge. This measurement allows an approximation of the residual capacity.
See bellow Unibat batteries data:

As mentioned, the voltage when the battery is rested give an approximative idea of the remaining capacity. It is a specific indication only given by Unibat batteries. Indeed, with other batteries, the fact the voltage is higher does not guarantee a higher capacity. The only way to know the real capacity of your battery is to charge it then unload it and to measure its restored capacity with a tester such as EMROL ones.

ADAPTED CURRENT INVERTER

In order to preserve your battery against excessive discharges it is imperative to use a current inverter adapted to your battery capacity.

PERFORMANCE

Number of cycle
Capacity retention

Number of cycle is determined according to:

• Unload velocity is made in C10 it means 10% of battery capacity per hour,
• Then one complete charge is made.
• Maximum number of cycles is reached as soon as returned capacity represent 80%. After this rate, the battery can still make cycles, but it cannot be taken into account in its cycling calculation.

NB : DOD XX% means Depth Of Discharge XX% = unload at XX%

Capacity according to temperature

A low temperature reduces remaining capacity.
For example, for a temperature of -10°C with an unload rate of 20% of the capacity (0,2C), the available capacity will be 70%.
Also, in order to completely enjoy Unibat batteries performances, it is recommended to have an ambient temperature between 20 and 25°C.

Self-consumption

The self-consumption is more important with high temperature.
Also, in order to avoid deep unload after period of non-use, it is recommended to charge your battery regularly (every 3-6 months).

WARNING AND ADVICE

• Maintenance : check the wiring and all connections at least once a year.
• All works need to be done according to the country rules speaking of electricity.
• Devices used in the installation such as connectors, cables, fuses, disconnectors, … must be adapted and in conformity with laws and regulations enforced in your country.
• This device is not designed to be used by people (including children) whose physical, sensory or mental abilities are reduced, nor by people lacking experience or knowledge unless they have benefited of supervision or prior instructions concerning the use of the device given by a person responsible for their safety.
