i buy the battery because of that post so believe me, im aware of... The battery is a brand new item from a german manufacturer of pollarcell goods (premium battery as they claim to be)
I order it at ebay for GBP 17.90 (US $23.28) but i had a 10 dollars coupon so i just had to pay 13 dollars plus free shipping. It took 9 days germany - argentina so WOW not bad, bad is the postal service here but anyway, after two months local shipping i got the battery; here:
and then i proceed to replace it (u can see i still had an original battery replacement (was excellent but after so long i can only get 3 nice hours of use)
so after all the waiting the battery wasnt working!!!!!!!!!!!!!!!!!!!!! nothing, was like no battery there at all, the bolt was gone as soon as i took the power cord away.
I had two options, send it back (and wait 3 or 4 more months with a battery that exponentially decrease its performance day after day) or open it and see what is going on with a small chance that if nothing is wrong i lose the 13 dollars because the warranty is gone...so guess what
those two metal plates have to make contact with each other so, after fixing that with some tape (i guess u can solder with tin also) now the battery works fine
now i will charge it fully and in a few days i will update with the performance in a regular day and sot test. Thanks
