    Default Rechargables Holding Duration

    How long can you not use a fully charged set of Rechargables and have it hold it's charge effectively?

    Anyone knows?

    Kindly advise.

    Cheers!

    Depends on the type of rechargeable.

    From what I have read, a few months for NiMH, a few years for Lithium.

    read that NiMH lose abt ~1% charge a day. so in 10 days time, you lose abt 10%!!!

    I generally top up all my batteries before I go for a trip.

    Top up?

    Erm... is it wise to re-charge a set of rechargebles that has never been used or half used?

    I'm using 1600 NiMHs.

    A few months?

    So can i safely assume that the charge would hold at full charge or something close for abt a couple of months?

    Kindly advise.

    Well I wouldn't COUNT on it. I generally use my batteries every day. But I HAVE had fully charged NiMH AA's die on me after being on the shelf for a couple of months.

    If you have no recourse to a power supply, there are a few options.

    1. Get a car-powered recharger. Some of the rechargers have an option to plug into a car's cigarette lighter.

    2. Get a solar powered recharger. These are a bit more esoteric, but are available, if you know where to look, on the web anyway. Not sure where you can get it in Singapore.

    3. Get Lithium AA's. These are increasingly hard to find. They're not the same as Lithium-ION rechargeables, and they're NON-RECHARGEABLE and expensive, but they last and last, and shelf life is measured in decades. Use them as a backup when you're rechargeables die on a field trip. They have the advantage (over alkalines) of a low internal resistance, just like your NiMH and Li-ion batteries, so they work well for high-drain applications.
