[apologies to the list for not trimming the OP's post... some posts come in as one long line of text -- that Tbird fails to wrap. This was one such post... :< ] John D.

Or, if you do, you may decide it's not worth the price! :> I simply removed the battery from my machines (it is soldered to the PCB but comes off easy -- remove the plastic clip-on bracket before doing so) and soldered a pigtail with a two-pin connector on the end. I chose the connector to mate with the 3xAAA NiMH's batteries that I have (probably surplus cordless phone packs?). So, I just plug a new battery whenever (*if* ever!) one dies. (so far, the replacement has never died). The plastic "clip-on bracket" is just the right size to wrap around the NiMH battery -- though I also put a piece of self-adhesive velcro on the battery to guarantee it never flops around inside the case. And, a small diode (4148/914) in series with the pigtail as "cheap insurance" to guard against a battery plugged in backwards (I suspect the PCB artwork may not contain such a diode -- though it *might* for UL).
