I have a predicament: I just bought a Motorola HT1250 at a hamfest. It came with an Impres battery model no. HNN4002a, and 2 chargers, the first being a impres model WPLN4114AR, and the second being Motorola charger model NTN8831A. Neither charger will charge th radio, excemt the NTN8831A charger, in which I have to shove crumpled up paper in it to even charge. Also, the battery doesn't fit that good in either of the chargers. If anyone has any suggestions or comments on why this is, I would greatly appreciate it.
