Rechargable Batteries

[whitmore]

... the original battery on the mother board was 3.6V, so that's one reason I chose to use the battery packs with three 1.2V rechargeables.

It's a tad inconvenient to change chemistries, OR to remove batteries to recharge; that
original battery could have been a common lithium cell (like the infamous wired-in cells in the old Mac II ).

Those are still available, but shipping will cost ya...DigiKey stocks and sells them.

Another vote for Eneloop NiMH batteries. Although the Amazon Basics low-self-discharge NiMH batteries seem to be good and are about 1/3 the cost of Eneloops.

A bonus of using Eneloops (compared to alkaline) is that they don't leak and ruin your equipment.

The original battery on the mother board was a stack of three 1.2V batteries soldered to the MB. I soldered jumper wires from the MB to remotely mount two switchable 3-packs of AA batteries in parallel so that the MB never loses power during a change of batteries. I've been changing the batteries every six months and it has worked out well for the past 14 years other than the life of the rechargeable batteries not being what I would expect them to be. It sounds like the new Eneloops may be the answer.

Again, thanks for all of the feedback.
