I am looking to purchase a rechargable light system for my bicycle. There seems to be two choices for batteries - Ni-MH and Li-Ion. The Li-Ion are much more expensive, so I have been looking at the Ni-MH. My question is: Do Ni-MH batteries have a memory? I do not want to spend a lot of money only to find out I reduced the run time because I charged the battery too often.

no memory in NiMHOpportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison -
the Li-ion costs more, the advantages are, lighter weight and more capacity and higher voltage for the comparable physical size.

I bought the dual lights from JetLites (http://www.jetlites.com/) in October
2000. They run off Ni-MH. I use them for bike commuting and really only
after Day Light Saving in the fall through winter. So they sit dormant for
most of the year and every year I charge them up, they light up just fine. I
will normally charge them up every night when they are being used. These
cost me a pretty penny. If/When these batteries do die on me, I'll
probably open up the battery housing myself and replace them myself.

If you go with the Li-ion, besure you ONLY use the charger that comes with it or a charger that has settings for Li-ion.
I use both types with my helicopters and both work well, but the NIMH are heavier and larger for a given size.Larry R. Rogers

Another major difference between the Li-Ion, and NiMH, is that as soon as you take the NiMH off the charger they begin to self discharge.
They will lose most of their charge in a couple weeks (the actual time depends on a bunch of things).
The Li-Ion batteries tend to not discharge on their own (as much).Comment

I used to have one of those in college. They actually add quite an additional load to the pedalling (I could always tell) and of course they would go out every time you slowed and stopped. Adding a charging circuit would add more to the load. And, it tore the heck out of my gum sidewall racing tires...Loring in Katy, TX USA

Thanks for all the responses. It sounds like the Ni-MH will serve my needs, and my wallet, the best.\"Experience is the toughest teacher. You get the test first and the lesson later.\"Comment
