Title: Why would anyone purchase a manual trickle charger?
Review: It may or may not have worked. However, it requires you to monitor the battery being charged, and remove it before over charging! For a few bucks more (sometimes less), you can get a trickle charger that can be left attached to the battery indefinitely (all winter) without causing damage. Just hook it up and forget it! Don't waste money on a manual trickle charger.
