TYT UV-8000D Battery Capacity Test

Date: 23/01/2017

We have found that Chinese batteries often overstate their true capacities by a wide margin. This battery is rated at 3600mAh. We placed it on a discharge current of 250mAh with a cutoff voltage of 5.4V. After about 11 hours when it showed a discharge of about 3,000 mAh, it cutoff after 6.4V. It had reached about 22 watt-hours, which means roughly that it would supply a constant 5 watt load for 4 hours. The overall capacity of this battery outperformed our expectations.
