I have a 10' John boat with electric motor, maybe once a year I will take it out. Any recommendations on a good reasonable priced charger.Thanks Mike

Recharging once a year before you use the boat battery isn’t the best procedure. A trickle charger from Harbor Freight could be a good option to maintain the battery all year round.

A modest solar panel system would work well.

Use any common flooded battery charger. If you charge once a year then a battery maintainer will be OK, otherwise get a charger with more amps and maybe both types.

I have good luck with RC chargers. They have lots of features for the price. Can charge lithium or AGM or flooded batteries. The best part is having control over the settings. You can do a 16v equalization charge. Bring back dead batteries. Temperature compensate if you happen to be charging in really cold or really warm climate. I charge my 210ah golf cart batteries with a charger the size of my palm. Off hang guess it might only be a 10a max. Which is plenty to for an equalization charge. Not a good choice to be your daily high amp quick charger.

Holy Cow 20 pages of chargers on Amazon, getting an idea on pricing. Harbor Freight is next town over... I'll compare pricing.Thanks everyoneMike

Costco Mexico still sells the Schumacher two-dial wheeled charger. The first dial selects charge intensity, the second dial selects time.

It is every bit as intelligent as the user.
It is a battery charger, not a Wurlitzer Pipe Organ.

Dang Mex, that's $500. He can get a 4 stage 45A Progressive Dynamics PD9245CV for $200 and use that as a portable charger.

Best battery charger used to be Vectron 40 amp smart charger. Then it was Black and Decker but no longer available either. Closest thing looks to be Schumacher 30 amp smart with 100 amp starting power. I’ve used the old Vectron several times and it lives up to its reputation.

I would stick with this old 10 amp.

The other day I tried doing a 2nd charge, boat motor wasn't lasting will probably look for a quality Marine Battery.
You don't want a marine battery, you want a true deep cycle battery for your application. If you can handle a 130Lb battery THIS would be an ideal battery for your motor. It would be best to recharge it with a 30A charger.

What he said. ^
2 different possible needs here.
1 is battery maintenance in the “off” season. This can be easy as hitting the battery with your old charger for a day every couple/few months, or hook it to a little battery maintainer continuously and not worry about it.
2 is “rapid” charging between uses. Which again could be accomplished with your 10a charger say overnight or several hours. Or a better charger. HF is never on my list as a place to get “better” tools though.

But regardless, you need to start with a good battery.
