Just my imagination, runnin' away with me?

Or do gel cells get MORE sensitive to cold when they get old?

I thought my ice machine batteries had finally bit the dust, but they cheered up immensely when the weather warmed up. One night below 40 without a heating pad, and they are back to useless, tho.

We're they always like this and have my past few winters snowbirding melted my brain?

I keep thinking these things are dead and then they sit bolt upright, throw off the shroud and get to working again. Meanwhile, I keep my eyes open for replacements.
