Milwaukee Tools just started offering a cool upgrade for existing customers with Ni-Cad tools. It’s a kit (2 batteries and a charger) that allows you to power the older Ni-Cad tools with their newer Li-Ion batteries. For around 2 bills, that’s not bad at all if you’ve got several tools already that you’d like to give the longer run-times.
What’s even better is that they’re offering a 5 year warranty on these batteries. with the first two years being exchange replacement.
Why would you want to do this? There are a couple of reasons. The biggest being that the weight of Li-Ion batteries is considerably less than Ni-Cad, which means your tool using experience will be much more pleasant. Li-Ion also have a longer runtime and more charges in their lifetime.
While this isn’t a “Throw out your old working batteries” type of an upgrade, if you’ve got some aged cells and are looking to freshen your personal battery inventory, this appears to be a great way to go. If the other manufacturers offered this, I’d be all over those, too. It’s hard for me to pass up new geek toys.
