Using AA for all my audio gear, I'm always hauling a bunch of them around.
I've been looking for a great/easy way to carry my batteries WITHOUT having to carry the big COSTCO case they came in.

I came across these, and am going to order 2 of the 12 AA cases.

Anyone else have a great way to carry extra batteries around?

For AA's, I use a plastic magnum rifle ammunition case cut down slightly so the ends of the batteries stick up where I can grab them. Each case holds 20 batteries. I use a similar ammo case for smaller-caliber ammunition (also cut down) for AAA's. They cost me about $2 USD each.

I use the cases that come with my Powerex batteries. They work, but it seems the Powerpax cases would be sturdier and not as prone to cracks in the plastic.

One thing I like is the batteries don't touch each other. I've always been a little concerned about this as a possible way they could "self drain". Technically, with the vinyl wrap around the casing on the Duracells, there shouldn't be a problem; however, maybe moisture or humidity is a factor.

Anyhow, I've got a couple battery-user devices where the batteries are packed really close together and they just seem to loose their voltage easier that way. Maybe I'm a little paranoid.

Thanks for sharing the link James.

This is probably a horrible question, but seeing this thread sparked my interest, Do you guys remove the batteries out of the handhelds/lavs/cadroid mics after every time you use them? Or are these just extra batteries for when they go dead? Thanks for your help and knowledge.

I remove the AA's after every shoot and put them in a box for flashlights, games, etc at home. Not worth taking the chance that they'll go dead on you in the middle of a shoot!

Seems like so many things take batteries - Home thermostat, flashlights, smoke alarms, portable GPS unit, powered mics, the JuicedLink that I just got (9v), magnifier with built in light, and the list goes on and on. The trick is to make sure they don't leak because that could be catastrophic.

I don't remove the batteries from everything all the time but there are things that I don't use year 'round so those I do remove at the end of the season. Other things, like the video equipment, I'll be taking out at regular intervals but not after every use. I've got a Fluke 77 for checking voltage and when that drops down to a certain point the battery gets re-cycled and a fresh one goes in.

Other things, like the bathroom scale for example, you know when the battery needs replacing because it gives an error message. ditto smoke alarms.

Just do what ever works for you to keep the battery from leaking in it's compartment and make sure the voltage doesn't drop below an amount where the equipment won't work Different items have different voltages where they become inoperative.

So, there's my two cents.
