Replaceing gauge panel batteries.

Hello.
My tach died the other day on my 1990 325i and I think
it was because I was messing with the wireing and shorted something.
I replaced all the fuses that blew out. Re-wired everything back how it was, nothing, so I took the cluster out and no loose connections either.

Now I'm left with the battieres.
Do I need to charge them before I put them in? Has anyone here done this before? Just any rechargable AA right?
thanks.

PS: Everything else on my cluster works except the tech.

ya i think you're supposed to charge them before you put them in. However, I do think that you have to use NiCad batteries (correct me if i'm wrong), not just any rechargeable battery will do....

When I changed mine, I bought a remote battery holder from radio shack and wired it to the board so that the batteries are accessible without taking the cluster out.

Good idea.
My batteries were actually glued and broke the connectors trying to unglue them. Little sonyo brand batteries.
