A problem with keeping an extra battery: the heat! Suggestions?

I live the desert and it gets HOT here. I bought a backup battery while they were on sale, and I love the idea of being able to swap it in when I am not near a charger. Now the most logical place for me to keep such a battery is in my car since I will likely need it most when I am out and about. But, when it is 110 outside and even hotter in the parked car, I am worried about how this will effect the spare battery.

Will the heat damage the spare? Is there anything I can do to avoid it?
 
Why not just keep it in your pocket or somewhere on your person?

The batteries can stand, to some degree, higher temps...but in a car in the desert is probably pushing it. I don't really have any knowledge on the subject though.
 
Yes, I will likely carry it with me when I am out for extended periods, but it would be convenient to have the car be the place where it generally stays. Otherwise, I know I will forget to take it with me! :0)

I think I will do some research on Lithium Ion battery heat resistance and see what I come up with.
 
I don't recommend keeping batteries of any kind in a hot car. Use common sense. Same with fragrances and cosmetics. If you are going to have an extra battery on hand carry it with you in your wallet or pocket.

It seems that extended periods over 85% degrees can shorten the battery's life.

It is not practical for me to keep an extra battery with me at all times (it will eventually get put through the wash!), so I think I will have to just leave it inside the house until those special occasions, like vacations, when I know I will need it and then I can pack it for the trip and carry it around for that limited period.
 
get one of those liitle cases that people use for zippo lighters. The battery should fit in there and then you can keep it on your belt.

I am so rough on things like that. I can't put a phone or anything on a holster without destroying it! :0)

I think the time when it will be most useful is when I am on vacation and spending all day out. I can definitely keep it safely in a pocket for those occasions, just not every day.
 
I would get one of those boxes that you put some AA batteries in, and use it to charge your phone from on those occasions when you need it.
You can leave it in the car and not care much about it. Alkaline batteries aren't too quickly damaged by heat.

Oddly, a quick Goggle didn't show anythiong good, but I know I have seen them before.
 
Yes, I have seen those before as well. I wonder if they charge faster than a car charger (which is much slower than than a wall charger).
 
I've been thinking of getting a spare. I had multiple spares for my incredible. I just carried them in my pocket with my wallet.
 
I have a spare I carry with me on occaisions where I might need it...but to be honest, I usually just switch to 3G to extend my batt life if I know I'm gonna be out and about for a while. Turning 4G off litterly doubles my battery life, if not more.
 
I kept mine in my pocket but now I have the Verizon Extended Battery and don't need one anymore.
 
I keep my spare in my pocket.

If you want to keep it in your car, back a cooler in your car with ice packs and put your battery in a protective case inside the cooler.....if it's 110 degrees, you might want to keep some bottled water handy too.
 
One of the things noticed when I was the VerizonWireless rep for about 300 soldiers was that, when carried in the pocket, the moisture window on batteries turned pink faster. Turning from white speckled with red to pink was indication of the phone being subjected to moisture, and is one of the first things customer support checks when cell phones are turned for warranty coverage when they arrive not working. Most carry their cell phones in a front pocket, which is near the groin, which is...you know, humid.

It's a bit unrealistic to do so with a smartphone, but spare batteries will last longer when carried on person if placed inside small plastic bags with those silicone gel moisture-wicking packs (like what you find in camera carry cases/etc) to pull moisture out of the air.
 
Never had that problem. Lighten up! Ha-ha!
