I’ve had our Canadian Tire Yardworks lawnmower for over 2 years now, and like everyone else, …I’ve dealt with the crappy 24v batteries.
But I’ve developed a system. I currently have 3 batteries that I use to mow the lawn. In most cases I can get through the lawn with one battery – before I needed all 3 batteries. But by draining them with a home-kit I made up (with generic 12v car light bulbs) it helps “condition” them.
With this “system”, I am draining the batteries to a minimal level, and recharging them to full-capacity.
So far, it seems like it is working well.
