I was charging my peak performance 2400 mah battery pack the one day and all of a sudden its at capacity of only 400 mah. The battery was fine and charged around 2 amps or so everytime. I'm using a venom pro charger plus but was using a duratrax piranah charger previously. I've also charged other batteries on the same charger and their fine so its not the charger. So my questions are why would this battery just die out of nowhere and is it because its a nicd? Thanks in advance for any advice given, Steve
