Notebook battery shot, meed help locating Li-ion batterys.

hey guys i have read numerous tutorials online about replacing the Li-ion batteries inside of old notebook batteries instead of paying $120+ for a whole new unit. i have successfully disassembled my battery and created a circuit map of there location. now the problem is finding new cells of the same voltage and "mAh" ill include all the information and pictures i can.

information i found on the batteries:
"7000106756" - this number is different on every cell.
"LGR18650R" - this number is the same on all cells, i think its the serial or model number.

"BAT8TOSH" - this number is located on the battery unit itself.
"p/n 6500479" - also located on battery unit.

"A&TB" "MADE IN JAPAN"

here are some images but do to the rules for some reason " 1. You are only allowed to post URLs to other sites after you have made 15 posts or more."

so to view these images just delete the space in between the "h ttp"

Images of battery sticker and cells:

Thanks guys!

Try google for finding Li-Ion battery cell suppliers.

I found one place on google, but unable to post URL cause I need to have 15 posts or more to post URLs.

Before you try rebuiling the battery pack, make sure you know what you are doing and have enough knowledge in electronic circuits and batteries. You are working with high current and potentially explosive battery. Also, do not over heat batteries trying to solder. The battery can explode if you heat it enough.

You can calculate mAh rating by counting how many cells are there in parallel. There are two cells in parallel in your diagram. So, each cell should be 1800mAh. Generally, you can use ones with higher mAh rating. It will increase your battery life.
Every cell of Li-Ion battery is 3.7V and you have 4 in series. That is how you are getting 14.8V written on the battery pack you have.

 

thanks for the information! in parallel you mean 2 connected correct? is this it:

To view links delete the spaces between the "h ttp" and "h tm l" and "ww w".

 

Two connected in parallel negative to negative, positive to positive.

You should not use the one you linked above unless you can spot weld. Battery terminals cannot be soldered as it will not take solder. If you try, you may get the battery overheated.
There are cells with tabs welded on the battery.

Like ones here.

I recommend buying an oem replacement off of ebay.

 

I would also recommend buying OEM batteries off of ebay. Should not be more than $40-45 for most models.

 

i see one is a 3.6v 1300mAh and 3.7 2200mAh. whats the difference between those? i could use ether one of them right? and also when i start soldering my wires to those tabs i should be alright as long as i don't complete any circuits right?

nizzy1115, i dont think i can find the OEM ones. they are some foreign brand that wont come up in any of my searches. if you could find them and place a link to them it would be much appreciated.

 

...anyone?
