Rollei 6008i battery rebuild

Just rebuilt 3x Rollei 6008i battery packs using NiMH cells supplied by NOVAPHOTOGRAPHY on eBay.

First class service and instructions from battery seller.

Soldering was a bit fiddly and reassembly quite tight.
The plastic shield that prevents the spare fuse falling out is now much more difficult to move - tried using PTFE lubricant but didn't improve things much.
I'm not worried about that - I always carry a 35mm film canister in the bag with spare fuses - have never had to use one yet.
Had to make a small cutout on one of the plastic battery covers to allow the new battery tabs to fit.

Tools needed:

PH000x40 screwdriver (Wiha PicoFinish 261P)
Heatshrink insulation
Hot air blower (Butane hot-air blowtorch from Amazon - approx £8)
Heatsink thermal conduction compound (Maplin)
Craft knife to trim back the supplied heat-shrink insulation so I could solder the tabs

The batteries charge just fine in a Rollei Charger N - just remember to lift them out when the red light extinguishes after an hour and reinsert them for another hour to complete the charging.

Hope this is of interest / use.
Contact me if you need any further info or reassurance if you are embarking on a similar project.

One point I forgot to emphasise.

Good insulation is REALLY important - I used it on the negative battery connection (blue wire) as that was the easiest place to ensure the two terminals remained isolated.

On the old NiCad stack, I deliberately shorted out the connections to see how hot they would get (remember this was an old battery that hadn't been charged for six months).
The 1/4 inch metal connection tabs glowed ORANGE ! I have no doubt that if the battery was fully charged it could easily have caused a fire.

I dumped the batteries in a bucket of water and left them outside overnight; there was too much gas from electrolysis for me to feel comfortable about leaving them
in the garage, before taking them to the battery disposal facility at our local tip.

So please take care with your insulation if you perform this replacement; these battery packs have a lot of oomph behind them.

Did mine, too.... seem to work pretty well, too. Hope they hang on betty than the NiCads did. I like the 600* Cameras but the batteries were always weak like there. Seem to be fixed now.
