***** PLS WITH ME FOR ALL BATTERIES PRICE
Advantages of AAA battery:
1. It has the ultra-high capacity characteristics of lithium polymer battery, with the highest capacity at the same volume.
2. The battery is built with DC/DC DC lifting voltage regulator integrated circuit, and the output voltage is stable 1.5v throughout, making it an ideal voltage regulator.
3, built-in battery protection board, completely eliminate the lithium polymer battery overdischarge.
4, fully closed battery structure, to prevent battery leakage.
5, clean and environmental protection, low pollution.
