Product Information

The Exide Marine & Leisure Equipment Lithium-ion Batteries are high-quality, rechargeable batteries designed for marine and leisure use. With an integrated protection system and a battery management system (BMS), these batteries are built to provide reliable and safe power for your equipment.
The batteries come with a user manual that contains important safety information, guidelines for installation and operation, and instructions for charging and maintaining the battery.

Product Usage Instructions

Safety

General recommendation:

• Read and understand the instructions before operating or maintaining the battery.
• Only qualified personnel should install the batteries.

Installation / Operation:

• Before connecting the battery packs to your equipment, fully charge the battery (see section 2 of the manual). This will put the battery in good SOC and calibrate SOC calculation from BMS.
• Observe the operating conditions given in the product documentation.
• The battery contains a BMS with integrated protection and with the capability to disconnect all battery power resulting in 0 V and 0 A. A battery which gets disconnected by BMS during use can lead to immediate loss of function for connected equipment.
• Do not install or use in systems where sudden loss of battery power may lead to dangerous situations or result in malfunction or damage of connected equipment.
• The battery is intended for equipment use only. Do not use for starting power (engine crank) or other similar applications.
• If the battery is damaged, deformed, abnormally hot or emits an odor, please cut off the power immediately and stop using it and contact your local dealer.

Battery Maintenance

•  Exide Li-ion charger is recommended to be used. If using any other charger it must respect the charging requirements of the battery (see section 2)
• Depending on battery type, if the battery voltage is lower than 10 V / 20 V / 30 V the BMS will disconnect (over discharge protection) and enter sleep mode to protect the battery from further discharge. Apply charging voltage to wake up BMS and recharge battery immediately
• The user should verify the condition of all external cables and connections prior to each operation
• Before carrying out any inspection of cables the battery must be disconnected from the application and the charger

Storage conditions

• Disconnect all loads from the battery before storage

• In case of long term storage (>6 months), battery must be kept dry and frost free. Storage temperature 15 – 35 °C, recommended storage humidity 5 ~ 75%

• In case of long term storage (>6 months), maintain battery state of charge (SOC) close to 50% by maintenance charge every
  6 months. For seasonal storage (up to 6 months) charge the battery to above 50% SOC before disconnecting

• Suggested storage temperatures up to 1 month -20°C ~ 50℃, up to 3 months -10°C ~ 45°C

• If battery need to be stored for prolonged time (e.g. for winter), recharge them upfront and check battery open circuit voltage, OCV (voltage at total rest, ideally with nothing connected to battery terminals) regularly every 3 months

• In case OCV >12.6 V battery state of charge is above 10% and can be considered OK. Below 12.6 V battery should be charged. At 10.5V the low voltage protection is triggered.

• To recharge, use Exide approved Li-ion charger or other Li-ion battery charger (lithium iron phosphate, LFP) fulfilling charger specifications as described in this manual. To recharge a battery in low voltage protection mode, the charger must be able to start charging from 0 V. Make sure the charger is capable of activating also when battery voltage is 0 V (e.g. use power supply function, automatic starting function, or similar setting). Note that some chargers do not have this capability and will not be able to «wake up» a Li-ion battery from low voltage protection, refer to charger manual for details and use a different charger if required

Charging and Maintenance:

• Use only the charger provided with the battery.
• Do not charge the battery in temperatures exceeding 60°C (140°F).

BMS – Battery Management System

The battery is equipped with an advanced integrated electronic Battery Management System, BMS. The BMS monitors the state of the battery by measuring voltages, temperatures and the electrical current in and out of the battery. The BMS performs balancing of the battery cells inside the battery and operates the heater (for applicable products). Battery models with Bluetooth allow the user to receive information of the battery status from the BMS.
BMS has a self-learning and SOC calibration function. Calibration needs to charge the battery to 100% SOC
SOC on the mobile Application “Exide M&L” is calculated by the BMS. The BMS has self-power consumption, when battery is left in storage, due to energy consumption from electronics, this calculation may become inaccurate. Make a full charge to the battery to get accurate data.

BMS integrated protection

To protect or minimize damage to the battery from abuse situations there are built-in protection limits for voltage, temperature and current. Systematic or intentional triggering of the BMS protection must be avoided and may cause permanent damage to the battery.
When BMS low voltage protection is triggered, battery must be “waken up” by the use of a proper charger (w/o voltage sensing), and charged to 100% to calibrate BMS and get accurate SoC calculation.
WARNING! If the battery is used outside the permitted ranges the BMS will enter protection mode and trigger an electronic dis-connect of the battery. Disconnection by the BMS results in sudden loss of battery power and may lead to total loss of function for connected equipment.
BMS protection levels
For correct operation refer to recommendations and ranges (voltage, current and temperature) for charge and discharge in section 2.
BMS protection modes
BMS protection modes are listed below including trigger, release and possible or required action to restore battery to normal state. Triggered protection will be communicated via Bluetooth for batteries with this function.

Allow battery to cool down
Under temperature***| Temperature below allowed range, see levels for specific battery model in section 2.3 and 2.4| Temperature within range (~5 °C margin)| Allow battery to heat up. Apply charge to activate heater

Battery voltages are indicative only. Protection is triggered and released by cell voltages
Note that Bluetooth connection will be disabled while over discharge protection trigger is active
Batteries with heater will prohibit charge if temperature is too low (<0°C) and utilize charging current to heat up the battery. Charging of the battery will commence automatically once battery is sufficiently heated
