I have a Raymarine Ray101 handheld radio that takes 6 AA NIMH 1.2V 1300mah batteries. The batteries stay in the unit when placed on a dock charger. It is time for new batteries and all I can find are 2300mah or greater batteries. Will these be ok? Will the base charger recognize there is a greater current capacity or just charge to 1300mah. Any forseeable issues? Thanks. Chad
