I used my Battery Tender Jr all through the night last night. It's a slow charge charger/tender. It showed fully charged this morning as did the gauge on the dash. Hit the starter and it doesn't have the power to start. Look at the gauge and it's down a full volt immediately after trying to start. There's also a small amount of acid that seeped/leaked out of the battery.

What's the difference between a Ctek unit and a regular charger?

Thanks
