❓ Frequently Asked Questions
What is the design life of this VRLA battery?
This battery features a 10-year design life when operated at a standard temperature of 25°C (77°F).
Can these batteries be stored for long periods?
The batteries may be stored for up to 6 months at 25°C. After this period, or sooner if temperatures are higher, a freshening charge is required to avoid irreversible sulfation.
What precautions should be taken regarding the operating environment?
Keep batteries away from heat sources and direct sunshine. Do not charge in sealed containers and ensure they are not stored in spaces where acid gas is present.
What are the available payment and shipping terms?
We accept T/T, Western Union, and PayPal. Standard price terms include FOB, CFR, and CIF. Shipping is available by sea, air, or rail.
How should the battery be maintained?
While maintenance-free, you should perform regular checks. If the battery is not used, it should be charged once every three months. Use a cotton cloth for cleaning and avoid organic solutions like petrol.
What happens if the battery case is damaged?
If the battery jar is broken or electrolyte leaks, the battery must be replaced immediately to avoid acid corrosion. If skin contact occurs with electrolyte, wash the area thoroughly with water.
