Default 18650 batteries

Laptop Battery for HP COMPAQ DV2000 DV6000 V3000 - eBay (item 110597902875 end time Oct-19-10 17:45:01 PDT)

regardless of mAH, it's still going to be 6x 18650 batteries when taken apart correct? not a bad price at $2ea.

Default Re: 18650 batteries

I just did this with my laptops battery. I got 6 great working 18650 batteries. I guess the circuit must have been bad because these batteries hold their charge. Plus they're sony brand

Default Re: 18650 batteries

This gives me an idea My Fujitsu E8210 main battery died on me recently, I might be able to replace the cells and have it up and running again

Default Re: 18650 batteries

26/6 would be 4,33 each battery i would gues..
something that bothers me is Capacity 5200mAh, Voltage:11.1v, Components:6 Cell
So those 6 cells only provide 5200mAH together and just 11,1V? or is there some circuit inside that restricts it to 5200mAH and 11,1V?

Default Re: 18650 batteries

11.1v would be 2 sets of 3 batteries in series connected in parallel.

Capacity would be really low though.

Default Re: 18650 batteries

Think about it this way:
3 2600mAh cells in series makes a 11.1V 2600mAh.
2 11.1V 2600mAh batteries paralleled is a 11.1V 5200mAh cell.

BTW, 2600mAh isn't low capacity.

I know that, I just got the math wrong. Thanks for clearing that up.

I divided the 5200nAh into 2, then divided that number by 3.
