Very dead battery pack.

Sunday, April 16th, 2017

Not proud to admit this, but my battery pack is not just dead, but very dead.

I now have to recycle 102 CALB60AH batteries.  They were not doing well before I moved, and were neglected during the moving. A friend stopped by to help with removing the batteries, and they were so swollen that it has been very difficult to get them out of the boxes.

I was able to save 3 from the entire pack.

On the plus side, she did bring two large boxes filled with CALB100AH, so now I have to go hunting for the rest to fill my pack.

Battery heating

Something I now have to consider is how to keep the batteries warm in wintertime.  Fortunately, I don’t have to worry about snow or ice, but it does get close to freezing. So when I redo the pack, I will install battery warming pads – these will be plugged in when the car is plugged in – they have built-in thermostats, so it is set-and-forget.

That and some insulation around the side should help tremendously.
