Feature in details

Long life design
12V Gel series of AoKu batteries are long life design batteries. Normally in the alloy of plate, the percentage of Tin is 8%. For this batteries, we double the percentage of Tin in the alloy. Also we change the percentage the percentage of Ca in this alloy.
Valve Regulated Construction (Sealed)
12V Gel series of AoKu batteries are of the AGM (Absorbed Glass Mat) valve regulated (sealed) lead acid rechargeable type. The electrolyte is suspended in a specially formulated non woven glass mat separator. All the electrolyte is absorbed in this manner and provides a safe non-spillable battery.
Gas Recombination System
The gasses generated in the normal charge/discharge use of a rechargeable battery are internally recombined during normal operating parameters. In the fact in normal operational use, more than 99% of the gasses generated are recombined.
Safety and Automatic Valve System
If the pressure is over 2-5 psi the safety valve will automatically open and reseal. This promise that there is no any excessive accumulation if gas in the battery.
Heavy Duty Grids
The grids are made by heavy duty lead calcium tin alloy. This provides: Safety margin of performance condition, Excellent recovery capacity from deep discharge, Extra service life in either cycle or float application, Low self-discharge when it is not in working.
Float Service life of battery
12V Gel series of AoKu batteries is designed for float life of 10 years at 20°C(68°F).
Operation in any position
Because AoKu batteries are sealed and all the acid is absorbed in the special separators, these batteries can be operated in both vertical and horizontal position.
Wide Operation Temperature Range
AoKu batteries can be used in wide temperature range from -35°C to 45°C.
Available in flame retardant ABS material for the battery case V0
AoKu batteries cases can be make by flame retardant material V0. It depends on the requirement of customer.

Battery Storage
12V Gel series of AoKu batteries have excellent charge retention characteristics, meaning that the
self-discharge rate is low, less than 2% per month at 20ºC(68ºF). The state of discharge of a battery can be
determined by the open circuit voltage of the battery to ensure the battery do not over discharge while in storage.
To ensure the battery does not over discharge during storage, or when not in use, it is necessary to understand
what is meant by fully discharge. Typically a battery is fully discharge when the open circuit voltage reaches
1.92VPC. The higher the discharge current the quicker the battery reaches a fully discharge state, and the lower
current the longer it takes. When the battery has discharge the battery must be recharged immediately to 100% capacity.

Final Acceptable Discharge
In discharge a battery, lead sulphate (Sulphation) is formed. If the battery is recharged as soon as discharging is complete then the lead sulphate is converted to active material and acid. However, on self-discharge the lead sulphate that is formed may not become reversible again. That is it be recovered. The lower the voltage that a battery is allowed to fall to under self-discharge the more likely it is that the sulphate formation will not be able to reversed and the battery will be damaged beyond recovery.

Please pay attention to the following conditions of storage battery over self-discharge:
*The batteries should be stored in a cool, dry place 25ºC or below
*The batteries should not be stored in direct sunlight.
*The batteries should not be subjected to an external heat source.
* An adequate stock control system should be introduced.

Residual Capacity Test Result
Auxiliary Charge
When it is unavoidable to store the battery for 3 month or longer, periodically recharge the battery at the intervals recommended in the table below depending on ambient temperature. Avoid storing the battery for more than 12 months.
