Quality Control
We choose grade A cells, protective ICs made in Japan or Taiwan, and other high quality raw materials. We conduct up to 16 tests at each stage of assembly, including parts, work-in-progress and final product. Any defective parts are rejected. A protective circuit will prevent the backup battery from short-circuit, over-charge and over-discharge even under extreme conditions.

Maintenance:
Follow these guidelines to keep your battery operating to its fullest potential:
1. Recharge the battery once every three months when it is not in use.
2. Keep the battery dry and away from moist and corrosive materials.
3. Do not wash the battery with harsh chemicals, soaps or detergents.
