Sorry about the thread drift, but may I interrupt this discussion of mice and palmetto bugs with a diversion about winter storing a Speedster?
I've had one of those old school battery 'trickle' chargers for years and recently hauled it out again.
My battery has been cranking just fine, but, at almost five years old, it's probably nearing end of life. If I don't start the car for two weeks or so in the winter, I like to top up the charge.
This time, the ammeter on the charger was acting a little wonky, not telling me too much about charge rate, so I started thinking about one of those new-fangled 'smart' chargers that delivers a programmed charge and also runs tests as it does so to tell you how well your battery is taking and holding a charge.
Some research led me to this one, and praise Amazon, two days later, there it was in my garage.
Long story slightly less long, it seems to do all that it claims, and gives you a much better idea of just how healthy your battery is than those old school antique chargers. It's also said to be able to bring back some batteries from the near-dead, thanks to a special cycle that reverses plate sulphation. And, being smart, it can be left hooked up for months at a time, testing the battery periodically, shutting itself off when not needed, and back on again when the battery voltage dips.
It was 65 bucks, which is more than 20 bucks, but hey, it lights up with three different colored LED's, and THAT's got to be worth something, right?
