As with most Battery pack tools, they are great when they are new, then the battery goes to crap and you have to buy a new one. And these battery packs are expensive and generally proprietary so each tool manufacturer needs a different battery type. The batteries also have a short life span and end up in the land fill. I have a couple ways to service these tools making your battery costs very low and the battery tools much more versatile. Not only is this a GREEN project, but it also keeps GREEN in your wallet.
The best parts of this are,
-The dead packs are modified, not the tool, so I can pop out My Modified pack and put in a regular battery if I need to get to a tight area where the cabled battery would be tough to work with.
-This battery has a much higher amperage than the standard battery packs. I find it lasts more than 5 times longer than the standard packs on a single charge.
- The actual life of this battery is longer than the regular battery packs.
-Cheaper and universal. One battery, several tools.
Step 1: SAFETY NOTE!
Always work safely with safety eyeglasses and gloves when working with these packs. A slip of a tool while prying could hurt you.
I took an old battery pack and opened it up. This one happened to be a 12Volt and it had screws holding it together. It was easy to open. Some packs are glued together and are much trickier to open, but it is still doable. There is some 2 sided tape usually holding the batteries into the bottom of the tray. Just pry them out. Basically we are removing the old dead batteries from the pack and replacing it with a cable that runs to an external standard GelCell Battery.
