My cordless drill battery used to die after 15 minutes, but now it lasts over an hour.
I started storing it in a kitchen drawer instead of the cold garage, and the difference after a month is crazy. Anyone else find a simple spot change that saved a tool?
I read a Popular Mechanics article that said lithium-ion batteries lose capacity faster in extreme cold. My old lawnmower battery used to be useless by spring when I left it in the shed. Keeping it on a shelf in the basement now makes it start right up every year.
Remember my buddy's snowblower that never started? He kept the battery in his unheated mudroom all winter. Switched to storing it on a shelf in his living room closet, just a normal warm spot. Next season, it cranked on the first pull. He was so shocked he almost fell over. Just that little bit of warmth saved him a ton of hassle.
