Charging a battery and the charge red LED and the #1 cell red LED on the charger are alternating, back and forth.
Is this two week old, 5 cycles, battery toast?

How do batteries "normally" fail? Is it just a gradual loss of flight time?
Buk said:When I plug in just the main power wires the green light flashes. Plugging the balance wires either by themselves or at the same time as the power wires, the reds start flashing starts.
I had the props off today to check motor balance and I used this battery. Shortly after turning on the motors, RPM started to decrease. The battery isn't charging at all. If go to Radio Shack perhaps they have a mate with wires to the balance plug and maybe I can check continuity of the three cells.
Not that these efforts accomplish anything, I read the fine print on the invoice and it says no returns on electrical items. Ugh.
Thanks for your comments.

take it to a hobby shop and see if they have a better charger to try it out on.

Although the manual doesn't use the word bad, it does say plug in the charge wires first and then balance. It also mentions using the 2 amp setting in one paragraph and 2 or 3 in another, but did state the max with a 20w rating it is limited to 1.8.

Okay, I purchased a slightly better charger. The battery had one undercharged cell. After running the charger for 35 minutes the end charge was 12.46 volts and the cells ended up being 4.10, 4.16, 4.20. Are the cell differences too great?

Nope, actuallly they're low.... those differences are considered "normal", even if you charge and then balance the LiPo.

I haven't plugged into the Phantom to see if the Phantom likes the battery or not.
