0A:It is VERY easy to understand - the device can only count to 100,000. The capacity increments are 0.1mAh. Therefore, it uses 10 counts for 1mAh, 100 counts for 10mAh, 1000 counts for 100mAh, etc. The maximum amount that it can COUNT TO is 100,000 which equates to 10,000mAh. Whilst it can record for 1000 hours, it can only COUNT to 100,000 - so 10,000mAh is the memory limit.Answered by Coops on 16/08/2020Helpful (0)
