What did the bartender say to the set of jumper cables that walked into the bar? Why, he said “You’d better not start anything in here tonight,” of course!

Hey. I’m a dad and am allowed to make dad jokes.

But here’s the thing – there’s an excellent chance that natty set of thick 2-gauge jumper cables actually won’t start anything if you’re working with a battery that’s constantly flat. Constantly running a battery flatter than the Prairies is a one-way ticket to the town of No Start. That’s why trickle chargers were invented.

Designed to feed a small but measured amount of juice into a car battery, trickle chargers – also called battery maintainers – use electricity to replenish batteries at or near the same amount of self-discharge. Try to find one that shuts off at appropriate times, called a ‘float’ mode, so the battery doesn’t get overcharged like festival goers trying to buy a bottle of water.

Their most common use is to be connected when a car goes into winter storage, allowing the battery to remain at the ready for the first flick of the key next summer. Some also advocate the use of a trickle charger to boost a flat battery, since the gradual re-introduction of juice is easier on a battery than a sudden jolt. It takes a helluva long time, though.

We’ve gone through the options on Amazon and present our findings here. No more dad jokes, we promise.
