hi all, I've got a Teac R-3 DAB radio which has a rechargeable battery that no longer holds much of a charge. It used to manage about 3hrs at best but has taken some punishment as I use it for my site radio most days.
I could just replace the original battery pack quite easily but thought I'd see if I can beef up the run time with a bigger battery. What i'm not sure about is what I can get away with.
The original is a 7.2v 1600 mAh ni-mh and far as im aware I can use another 7.2v pack with a higher mAh and it should work as normal but last longer, although the charge will be slower. Does that sound about right? Would there be a limit to the mAh size of the new pack? Was thinking of using a 3800 mAh pack normally for RC cars, which should give roughly 2.5 times the run time. I've also got a 4400 mAh laptop battery I could use.
Alternatively I could use two of the 1600 packs in parallel for 3200 mAh.
I guess my main concern is if the radio will function ok and how well it would charge a larger battery.
any advice appreciated
