This should be an easy one for the lithium ion battery experts here. I dont know much about them so this is all new to me.
I rebuilt my laptop battery today. The old was made up of nine 18650 type lithium ion cells configured as three series connected sets in parallel. That is three individual cells (2000 Mah x 3) working as a single 6000 Mah cell. Then set up as three of those in series to make the battery.
I changed out the old 2000 Mah cells with new 2800 Mah cells so I have a 8400 Mah battery now.
The first time I put it in the computers charge monitor said it was at 0 charge. It took about 30 minutes to reach 100% charge.
Then I ran it at a normal rate (played a movie) for 92 minutes before the battery was down to 5%. I plugged it back in and now its been charging for 2+ hours and is still only at 42%.
Does the battery need to be exercised some?
And why the slow charge rate now? I dont recall it ever doing that with the old battery pack.
And will the charge monitor circuit in the battery pack have any problem with the larger capacity cells?
