When you’re underground it is essential that your electronic gear, such as lights, work.

We’ve been wondering, do you give the job of powering your vital equipment to single use batteries or do you opt for the rechargeable alternative?

Last Week’s Poll Results

The results of last week’s poll indicated that nearly three quarters of answerers had visited another country on a caving expedition. That’s neat considering that the result is higher than percentage of folks who have passports in most countries.

Thanks to everyone who responded.

    Actually, only once in a while, and it depends on the trip or situation. If it is a hardcore/exploration trip then usually only new alky batteries, and if it’s more of a recreational trip then I’m more temped to use rechargeable ones.

    The good side of being both a caver and a cave diver is that cave diving lights have advanced significantly in technology over the past several years. Big “can” lights that used to be about 6″ in diameter and a foot in length are now only about 6″ long and maybe 1-2″ in diameter, with the 9-12 hours burn time, rechargable, waterproof, and more than 1500 lumen output. I haven’t found any equivalent outside of dive lights that can hold up to rugged caving with that kind of quality.

    I use the custom rechargeable batteries for specialized caving lights like the Sten and the El Speleo.

    I do not use rechargeable double A batteries. In my experience, they do not hold a charge as long.

      When using rechargeable AA’s, you’ve gotta make sure to check out their mAH rating. Rechargeable AA’s only deliver 1.2 V, unlike the actual AA which delivers 1.5, thus making them a bit weaker and needing a higher draw to survive.

      You can find a lot of Rechargeable AA batteries that have 2450 mAH ratings or better, that should last significantly longer than traditional AA batteries. On the flip side, cheap rechargeables are only around 1300 mAH and don’t last very long.

    All of may electrical devices (lights, camera, ipod dock) use rechargable batteries.

    Rechargeable StenLight batteries (primary), and rechargeable AAs (2450 mAH+ as Brandon points out) for my Black Diamond Icon (secondary). With one regular and one double StenLight Lithium battery, I have yet to switch to a secondary light, even on two-week expeditions.
