Hi, I bought the F40 replacement battery, it only has one cable, the old one has 2 cables, the old one goes around the front of the battery, and I believe it might for heat? You can see it on the front of the battery on your instructions for changing the battery in the Maxx 2. The replacement battery doesn't have that.Now to my problem. I changed the battery, super easy, no problem. It powered the phone just fine, but the battery would not recharge. I had ordered 2 batteries as my son has the same phone. Both acted the same way, powered the phone but wouldn't recharge. Do you think I am doing something wrong or do you think I might have bought 2 bad batteries? I bought F 40.
I ordered a FL 40 replacement battery but it only had one set of wires, not 2, it worked perfectly except it wouldn’t recharge. I am guessing that is what the second wire was for. Can you tell me what is the difference in the FL40 batteries? I need to be more specific that I need 2 wires, is there some other number or designation I need to use when ordering?
