Thread: Calculate battery specific charge/discharge. mAh/g

Hello

I require help calculating a batteries specific charge/discharge in mAh/g

I have the following and I just want to check if I am correct.
mA= 0.48,
Charge time= 15:06 = 0.252 hours
Discharge time= 8:17 = 0.138 hours
Active material weight= 1.304g

Specific charge: 0.48 * 0.252 = 0.121 mAh
0.121/1.304 = 0.093 mAh/g

Specific discharge: 0.48*0.138 = 0.066
0.066/1.304 = 0.093 mAh/g

Thanks for any help

I'm not sure why you're trying to relate discharge times to weight. Batteries generally have two essential factors; Voltage and Amp-Hours. Use Ohm's Law to figure out discharge time through a given load. But, if you're looking for the best Power to Weight ratio; Any Lithium based battery would be your best bet.
