Battery Problems - The unorthodox repair method - for the not faint of heart.
Been lurking on here for a couple of months, I have the same problems as everybody else. Bought my laptop in June by late november I had 99% and the charging light lit, from there by charge has diminished to 56%.
From what I can see by reading the entire thread..... no actual solutions to this problem have been found. Something is either defective with the battery or the charging system.
So here's my unorthodox repair method. I voided my battery warranty, by cutting the battery compartment open. Used an exacto knife to very carefully cut around the edge of the battery - in the little grove. It takes a while but you can break the plastic seal. You have to be especially carefull when cutting on the backside of the battery around the power connector. I nearly cut a couple of traces on the circuit board..... got lucky.
Inside is a small circuit board about 6 inches long, it extends from one side of the battery compartment all the way to the power connector. I can provide pictures if you guys want. The batteries inside are ICR18650-22E, you can find info about them from herehttp://www.samsungsdi.co.kr/contents...R18650_22.html
Inside is a small temperature thermistor and about 4 wires connecting to various points inside. A main +/- negative lead and two smaller leads probably used for short circuit detection or lower voltages.
Now I had purchased a new battery battery pack for a customer (acer laptop). It was the wrong one, so I decided to try using the batteries from it. Cutting it open revealed a very similar battery with 10% less capacity from some other manufacturer. The battery had the same physical dimensions, and had solderable metal contacts. So out comes the soldering iron and about 30 minutes later I have a new battery pack. For now I'm just using a couple of wraps of electrical tape to hold the battery pack together, I can replace the batteries again if need be.... next time perhaps I can find better batteries than the ones asus provided
It took a little over two hours to fully charge and it's working so far. Maybe this solution will work..... either way I can rebuild my own battery pack. For now my charging light has gone out.
MMeter reports that the battery has charged to 54195mwh about 15% shy of 64000 the reported maximum capacity. (Batteries are 10% smaller)
I was thinking that a tiny microswitch might help, I could shut off the battery pack once it was fully charged. For now I'm just going to monitor the charging conditions of the battery.
Hope that helps
Will keep you all posted
