    I need to buy a battery charger for my Radio Shack AAA batteries. I see
    two chargers at Radio Shack, one will charge in 5 hours, the other in 13
    hours. What are the advantages/disadvantages of each? Thanks.

    Usually the faster that you charge, the shorter the total battery life.

    The main disadvantage of both, is that they come from Radio Shack

    Thanks, but what do you base this opinion on?

    Fast charging is more convenient. But, with many types of chargeable
    batteries, faster charging may make a shorter life for them. I personly
    prefer the fast charge. In the end, you are still saving a lot of money for
    the batteries, even if they have to be replaced one or two times a year.
    After about 2 to 3 years, most chargeable batteries are scrap anyways...

    Has anyone ever heard of rechargeable Ni-MH batteries not working below
    32 degrees temperature?
  8. NiMH batteries will supply voltage under 32 degrees, but it isn't
    wise to charge them that cold. The oxygen ion recycling mechanism
    slows down a lot and you could build up a lot of pressure, eventually
    causing it to vent.
