Only batteries to be used on the T90A is original 1300 mah
as well as one i found from a long island battery dealer in hicksville ny
( W&W i think) that is 1400 mah
The T90a battery pack has to be a Li-Ion type to TX at 5W.
I've read if you use anything else, the TX power is 1/4 W max.

Then again, .... my fancy factory Icom Hi-dollar HT Li-Ion pack has not gone belly-up yet.
