Which Rechargeable Batteries Do You Use?

kramer2718 asks: "I go through a lot of batteries in my digital camera, remote controls, etc. I'd like to go to the rechargeable route for the environment and for my pocketbook, but I don't know which rechargeable batteries are the best. Can anyone out there give me some advice about which brand and types of batteries work well?"

  1. NIMH here by Anonymous Coward · · Score: 5, Informative

    18 pack of ray o vac NIMH's. Energizer charger.

    Further, I made an effort to simplify devices around them:

    1. My flashlights use them
    2. My mp3 player uses them
    3. The flash on my canon XT uses them
    4. I bought a bluetooth headset that uses them ( 1 x aaa ) Motorola H300
    5. My wireless mice use them ( both use 2 x aa )

    YMMV, but NIMHs are a good way to go. LiPo and LiIon I dont think are really as common or as inexpensive.

  2. www.thomas-distributing.com has it all by holden+caufield · · Score: 5, Informative

    I have no connection to this company, other than being a satisfied customer, but what you want to do is to purchase Powerex NiMH batteries, and a MAHA - MH-C204W Smart World Travel Conditioning Battery Charger.

    Then you will be a satisified customer too.

    I'm afraid you're mistaken about the "memory effect". There never was a memory effect in consumer-grade batteries, NiCd or NiMH. What people experienced, and what was called "memory effect" was in fact overcharging due to crappy timer-based chargers.

    When you put a partially-charged cell into a timer-based charger, the charging circuit won't shut off until well after the cell is cooked, thus the directions to fully discharge the battery before recharging.

    However, with modern electronically controlled chargers (Such as the Energizer 30 or 15-minute NiMH charger) this is no longer an issue, and the wear on the battery caused by deep cycling far exceeds any risk of overcharging the cell.

    My suggestion is to use NiMH cells in anything that tends to wear down the batteries fairly quickly (cameras, portable electronics, etc) and get a GOOD charger; a charger rated for 30 minutes or below will be electronically controlled and will maximize cell life. Be prepared to spend $50 on a charger.

    For any low drain applications such as remote controls, smoke alarms, flashlights etc, your best bet is to use the non-rechargable lithium batteries that have recently become available in AA and AAA sizes. Unlike NiMH, NiCd and Alkaline to a lesser extent, Lithium batteries do not self-discharge over time, so they're perfect for applications where you want a long shelf life between uses. Lithiums also perform well in high-drain devices, but other cell types are much less expensive for such uses ('titanium' alkaline or NiMH).
