The big lawn mower is having trouble starting. It is strictly due to a low battery. I’ve been nursing it along for over a year now. I think the heat finally killed it.
At least I get to replace my “R” battery with the right one.
A few years ago, I needed a new battery. I went to the hardware store to get a U1-3T battery. All they had were U1R-3T batteries. The R means the poles are reversed. I was impatient so, I bought one and barely managed to get it installed. Flash forward a couple of years and now that’s fixed.
