There are few that that are more irritating than when your rechargeable batteries just go dead right before you finish a job. It might be your drill, your cell phone, or even your digital camera. Over time batteries just simply begin to lose their ability to hold a charge, even worse they could stop holding a charge all together.
However, there is an incredible trick that I discovered quite a while ago that allows you to make your batteries work like the day you bought them and sometimes even better. I have even taken batteries that were completely dead, wouldn't hold a charge, and made them work again.
Batteries usually begin to lose the ability to hold a charge after a while because of heat build up. When you don't completely discharge a battery before charging it again it builds up this heat 'memory'. You can fix this problem just by putting the batteries in a freezer overnight.
You may have also noticed that your batteries may not hold a charge over a long period of time. I often don't use my digital camera for months. It can really help the life of the battery if you put it in the freezer before topping it back off.
You can even leave your batteries in the freezer for extended periods of time. I have forgotten about some batteries I left in the freezer before and to my surprise they still worked just fine. They may have even worked better than they did before.
The only noticeable change after being in the freezer that long is that they take a long time to charge the first time. If you are used to charging a battery in say an hour, then it may take an extra fifteen minutes to half an hour. The charge will be much deeper than it normally is though.
I have also resurrected batteries from the dead using this trick. Sometimes if you use a battery too many times it just stops holding a charge all together. Most batteries can handle being recharged 500-1000 times before this happens, but this can happen in a short period of time with items that we used often.
I have heard fears that doing this to your batteries may cause them to explode, or meltdown like some of the ones we have seen on tv. I have never had a problem like this. It is important to remember that these types of problem are caused by heat build up, which you are preventing if you leave them in the freezer.
