Batboard

I have a few XTS IMPRES batteries that are not holding a charge for very long. I got them as new old stock. They are all Ni-Mh. I have been charging them in an IMPRES charger.

I also have an AT-2000IFD conditioning charger. Would this charger help re-condition my batteries better than the IMPRES system?

Does anyone have a user manual for the AT-2000 IFD?

Thanks guys!
