LP12-5.4 (12V5.4AH)

Using oxygen recombination technology: maintenance-free
PbCaSn alloy for plate grids: less gassing, less self-discharging
High quality AGM separator: extend cycle life and prevent micro short circuit
ABS material: increase the strength of battery container. (Flame-retardant ABS is optional);
High purity raw material: ensure low self discharge rate
Silver-coated copper terminals (T1, T2 terminal), brass insert terminals and lead terminals improve the electric conductivity

Self Discharge Characteristics

No supplementary charge required(Carry out supplementary charge before use if 100% capacity is required.
Supplementary charge required before use.Optional charging way as below:
1. Charged for above 3 days at limted current 0.25CAand constant volatge 2.25V/cell.
2. Charged for above 20hours at limted current 0.25CAand constant volatge 2.45V/cell.
3.Charged for 8~10hours at limted current 0.05CA.
Supplementary charge may often fail to recover the capacity. The battery should never be left standing till this is reached.
