I think the Miata’s battery might be ready for replacement. I don’t know how old it is; I haven’t replaced it so it could be the original (and 7 yrs old). It has been dead twice in the last two weeks, so I have it in the kitchen on the charger. Maybe I can get a little more life out of it. It looks like I’m in good shape as far as homework is concerned. I’m sure there are incremental improvements I could make, but the hard stuff is solved. I might play bridge or a computer game with some co-workers this evening.
