    I don't think Mooch has tested this one (yet), but I'll wager a guess. Going by Efest's track record, and assuming that this is indeed a 3500 mAh battery, it might be some of the newer 10 amp batteries (e.g. LG mj1). It's definitely not a twenty amp battery. Furthermore, it's probably a worse battery than the non-rewrapped original.

    I agree with @KenD. Efest typically exaggerates, wildly, the current rating but is usually pretty close with the capacity rating. I think this is a 10A battery that is being rated by a useless marketing-driven "pulse" rating. If you use it as a 10A/3500mAh battery it will probably, hopefully, work ok. But since you can buy the excellent 10A/3500mAh LG MJ1 for less money there aren't a lot of reasons to buy the Efest. Unless you really like the color purple. :)
