Recently replaced a battery charger with this Schumacher model. I used the 1st one also a Schumacher for 20 years. It's really comes in handy for a quick charge on batteries.
I use waterproof Battery Tenders on the boat batteries. They deliver an 800 milliamperes charge that will recharge most cranking & trolling batteries overnight for most fishing situations. A light indicates when they are charging (yellow) & fully charged (green).
Just plug in an extension cord when you come in and forget it.
The first 5 days after the Weekend are the Hardest.
