I will be replacing my laptop batteries with 18650's, however my question is as follows.
Battery pack = 6 cell (18650 type Li-ion battery)
Time : +/- 3-5 Hours if memory serves.
My laptop power supply is 19V, 3.95A.
My laptop battery stats are 11.1V, 44mAh, 48.84Wh.
I have already done battery tests with my multimeter, seems like I have 3 banks of 2 since the voltages are as follows:
- 2 x 3.786V
- 2 x 3.808V
- 2 x 4.089V
This is a 2 part question:
With my battery stats, is there a method I can calcuate the maximum time my laptop can/could last from a full charge?
Can I use 18650 batteries that have e.g. 4000mAh?
