Product Description

This lithium battery directly replaces a 12v 7Ah sealed lead acid battery inside small UPSs.

This battery has a BMS specifically designed for use inside a UPS that takes a single 12v 7Ah lead acid battery.

This lithium battery is an upgrade in terms of how many cycles the battery can do (how many times it can be drained before it needs replacing), but it does not store more energy than the old lead acid batteries it is replacing.

This battery is ideal if you use your UPS to power a device for a few hours and the frequency of load shedding is killing the lead acid batteries.

The load determines how long the UPS can be operated. These UPS are about 75% efficient. From testing a 12W load will run for 4hrs+, a 24W load will run for 2hrs+, a 50W load will run for 1hr+, and 80W will last about 40minutes.

NOTE 1 : Although this is a 6Ah battery, it perfectly replaces a 12v 7Ah old lead acid battery since 100% of capacity is available and does not decrease like lead acid it is replacing. NOTE 2 : The maximum load on UPS cannot be more than 100W, then BMS protection will trigger. NOTE 3 : This battery BMS is built specifically for a small 12v UPS. Normal 12v 6Ah/7Ah lithium batteries do not work correctly.
