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?

Still need help please.

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.

Please any help would be appreciated.

Thanking you in advance.

Janie

Missing step from this guide — you need to move the inductive charger piece over, or the phone won’t charge (even though battery charge indicator comes on), as users like janiew48 found. Even if you break the coils (I did, the glue had turned to cement, basically) you need to plug the connector itself in. Once I did that, replacement battery worked perfectly!
