I bought some Peak brand rechargeable spot lights at an auction from an out of town vendor. I plugged them in to charge for 36 hours. One won't charge, the red charging light won't come on. The other 3 will charge, pull the trigger and watch the light dim and go out in less than 10 minutes. Let them sit for more than 24 hours and the light doesn't come on. I'll return them when the vendor comes back.
