6v 12ah lead acid battery sealed rechargeable lead acid battery 6v 4ah 20hr For UPS back up power
>Main characteristic
1. Using oxygen recombination technology: maintenance-free;
2. PbCaSn alloy for plate grids: less gassing, less self-discharging;
3. High quality AGM separator: extend cycle life and prevent micro short circuit;
4. ABS material: increase the strength of battery container. (Flame-retardant ABS is optional);
5. High purity raw material: ensure low self discharge rate;
Why UPS use lead-acid batteries?
The reason why lead acid batteries are preferred for UPS applications is the lower cost and relatively lower-tech battery management requirements. Lead acid battery performance degrades for several reasons. In an uninterruptible power supply, the battery set is used in a standby power application.
How long does UPS lead-acid batteries last?
UPS batteries (traditional sealed lead-acid batteries) tend to have either a 5-years or 10-years design life. Some may last for 10-15 years. Yet performance will significantly reduce overtime to a degree where it is not safe to use in a UPS system. So you should figure out its service life instead of design life.
