1. My previous 4.8 NiCd packs all had only a red wire and a black wire. My wife bought me a 1400Mah battery but it has a red, black, AND white wire. What can I use this battery for?

2. I purchased a 1800mah, 7.2V Lipo for my ignition and when I put it on my Accu-cycle elite, it only took 600ish mah to charge it. Do batteries come "pre-charged"?
