Hi, all - I have an AIWA AM-F70 that has given me good service. However, the 3.6 volt, 700 mAh AIWA battery -- #LIB-902, lithium-ion -- is not holding its charge. (It's a gum-pack shape). I can't locate a duplicate, but the Sony NH-14WM (3.7v. 1400mAh; NiMH) looks to be the closest and has more power, although the listed dimensions seem wider than my current Aiwa battery. Also, all listings say the Sony NH-14WM is compatible with the AM-F90 only; there is no mention of the F-70. Can anyone please tell me what the correct replacement battery would be? Many thanks in advance. Michael Cala mcala@si.rr.com
