I posted in another thread that I ordered a battery off of ebay from Hong Kong for about $4 with free shipping (to Vancouver, Canada). The vendor is called neewer: Lithium Ion Battery For LG P500/GW820 LGIP-400N P509 | eBay The shipping took almost 3 weeks (cheap international postal shipping). I charged up the phone for 6 hours the first time, as recommended. It felt just a tiny bit warm during the charging. It claims to have 2500 mA which is substantially more than the OEM battery. So far, I have had it on standby with the cell on but with no calls. I have only used a very small amount of display/wifi usage (1.5 hours, 2%). I am currently on vacation and have not used the phone much. After 3 days and 3hours, the battery still shows 30%. This is substantially better than my OEM battery (I believe even when it was new). I will recharge and test some more and let you all know. For $4, so far, I would recommend it.
