Ebay combo 1900mAh Battery update!
Surprisingly, I did hear back from the vendor. Clearly English is not his first language. His response:
"oh,sorry, buy batteries must be used repeatedly five can really fully charged, please use a few times, if that does not work I will be re-sent to you, thank you
If I'm interpreting him correctly, I think he means that I should cycle it through 5 full charge and discharge cycles and if it doesn't improve he will send me new batteries.
Well, surprisingly it is getting a bit better. Today(3rd charge cycle) after 1hr off the charger(with no use) it only dropped to 90% whereas yesterday it was at 83%.
So I'll give it a week and report back.
