What spare batteries do you carry when you're out and for what gear?

It's crazy how batteries have become such a larger part of the load...

Lot's of Kentli AA rechargeables for:

- Game Cameras
- Driveway Alarms (sensor and receiver for hog hunting)
- Rangefinder
- Need one for a backup for the ignitor on my Mr Buddy heater.

AAA's for smaller/backup headlamp

Rechargeable lithium cell for primary headlamp

About the same size rechargeable battery for Cellphone/iPad

At least half-dozen CR-123A's for Thermal Monocular and Thermal scope

With all this, I still wouldn't trade the use of any of the above. Once you figure out what you need, and have 'em, not a problem.

I keep a large pack of AAs with me and an extra feeder battery

AA for game cams, flashlights, weather radio, AAA for various flashlights, headlamps, TV remote, sq. 9V for smoke detector, Cs for one game cam & LED lantern. I don't buy anything that requires CR123s.

In my truck for hunting I carry the following:
2 boxes of AA batteries for game cameras 2 way radio and flashlights.
Extra 12 volt feeder battery (charged)
Extra 6 volt feeder battery(charged)

Mostly AA and AAA. For cameras, flashlights and headlamps. And some d's for the feeder!

AA, 6volt feeder (I run them in a series for 12volt service) and a couple extra Streamlight batteries.

For you AA users, I strongly recommend trying the Kentli rechargeables you can get on ebay. It's a bit spendy to get started, but they hold a charge well, appear to have a long cycle life (life between charges, after multiple charges) vs other rechargeable AA's I've tried and can be used with/without a solar panel on cameras.

6 - CR 123's for flashlights, a couple dozen AA for game cams
