Sure you can run a battery charger with a portable generator, but why not cut out the middle man, especially if you’re off the beaten path where you don’t want to haul around a large generator? This would be especially great for charging up an electric trolling motor battery or camper battery when you’re 150 miles from the nearest outlet.

Cordless electric impact drivers allow everyday mechanics to access the power of air tools at a fraction of the blah, blah, you’ve heard it before.
But — DeWalt’s thrown a doozy into the works by adding another 18V to the usual power rating for battery impact wrenches. Gentlemen, meet the DC800KL, a 36V 1/2″ impact driver with DeWalt’s latest and greatest battery technology on board. It’ll deliver 325 foot-pounds of torque, and ships with two batteries and a 60-minute charger for $479. Keen observers of the DeWalt range will notice that this is only 25 foot-pounds more than a cheaper 18V model, but the 36V battery has nearly 3 times the life of an 18V equivalent.
DeWalt’s done some great things with their cordless tools lately. They just introduced an upgraded lithium-ion battery pack for a new range of tools, but designed the plugs for compatibility with the older generation (which, while clever, isn’t what I’m after here). Most importantly, they’ve built fans into one of their 24V NiCad battery packs as a means of extending life.

Bear with me, there’s science behind this one. There’s a chemical for just about every single situation you can encounter under a hood (some of them more effective than others). However, when it comes to cleaning that scaly crap off your battery, the creme de la creme is something you probably have in your fridge. Nothing I’ve heard of cleans battery acid residue better, and this isn’t exactly expensive stuff. There’s a bit of a catch: cola has all kinds of ions floating in it, so it does conduct electricity, but not well enough to burn out your battery. Still, cleaning one terminal at a time is a safe bet.
It should be said, for the happiness of the Toolmonger legal department, that fizzy beverages are no substitute for most automotive chemicals. Mythbusters fans probably remember what happened when Adam and Jamie used cola as coolant. If you haven’t seen that one, well… let’s just say don’t do it!
