Steven Scharf said:Alas, it's the cost of the NiMH batteries, and especially a smart charger, that really drives up
the cost of a lighting system.
Once you have a smart charger, you have it for all sorts of applications, in particular portable
radios that you can make portable again by using NiMH batteries and putting away their wall warts.
So the cost spreads out.
It's the reverse in my case, the smart charger having been bought for radios and digital IC
recorders, and for AA's for the Cateye HL-1500's it's free.
I charge 10 AAA's a day; adding a night's AA's from the commute is free.
Smart chargers: for four AA or AAA the Maha C401FS is nice, with a slow charge option if you're not
in a hurry; for D C AA AAA and 9v the AccuManager 20. These are just what I have and they work
fine, there may be newer ones. A chief feature, the cells are charged individually rather than in
series or parallel. Series charges cells unevenly, and parallel may not charge a cell at all if
(very common) a contact isn't quite clean and you won't find out about it in time. With individual
charge, if the individual light doesn't come on, it isn't charging; and every cell gets its own
tailored charge.
You _will_ need it.
The NiMH batteries last a long long time. I've had to toss only a couple after several hundred
charges of a dozen. The per-use cost must be about zero.
