Generally Features: 

1. Sealed/Maintenance-Free: There is no need to add electrolyte, as gases generated during the charge phase are recombined in a unique "oxygen cycle", Gamko sealed lead acid batteries can be operated in virtually any orientation without the loss of capacity or electrolyte leakage. However, upside down operation is not recommended.
2. Long Shelf Life: A low self-discharge rate, up to approximately 3% per month, may allow storage of fully charged batteries for up to a year, depending on storage temperatures, before charging becomes critical. However, we strongly recommend that all batteries should be recharged within six months of receipt as it will enhance their long term life.
3. High purity raw material: Ensure low self-discharge rate. Silver-coated copper terminal (F1, F2 terminal), brass insert terminals and lead terminals improve the electric conductivity

Battery Use and Maintenance:

1. Please use constant-voltage charge.

2. In floating charge, the voltage is 2.23 to 2.27 per unit cell.
3. In cycle use, the voltage is 2.35 to 2.45 per unit cell, the max. Current is no more than 25%° C
4. Please do tighten the bolts to avoid sparkle and poor contact when the battery is in use.
5. Please do not use it near the heat source and open flame.
6. Please keep it at low temperature. Please change it while there is liquid leaking or damage.FAQ:
