The capacity unit of a lithium battery is mAh, not mA. English is mAh.
If your battery is 1000 mAh, this means that the operating current is 1 mA and the battery can operate for 1000 hours. If the operating current is 1000 mAh, it will only work for 1 hour. The larger the "mAh", the larger the battery capacity and the longer the battery life.
