Thread: Thoughts on using Battery Tender plus

The time the battery is at less than a full charge causes damage, even while it's being recharged. It's better for battery life to have a charger that will get them recharged overnight. 5A will do, but 10A is a good rate.

I'm a believer in battery tenders. I keep one on my Harley all winter and one on my 4 wheeler year round. However, it is my understanding that they are not intended to be a battery charger but a battery maintainer when the battery is at or near full charge. Check the operating instructions. I do believe they increase the life of the batteries when used properly.

I use a Battery Tender Junior on my starting battery during the winter while the boat is in the garage. It is not a battery charger. If the charge on the battery falls too low, it will not bring it up to charge. I have to use a charger then. But it does a nice job of maintaining the battery's charge while I store my boat for the winter in my garage. I just keep it hooked up to the battery. I have a Minnkota on board charger for my trolling batteries that I leave plugged in all winter. Just make sure your batteries don't go dry.
