What kind of maintainer do you use over the winter? Is there one that i can plug more then 1 battery into? I used a solor maintainer over the summer and never had an issue till i left the damn key on for about 3 months lol

All you have to do is jumper the batteries together in parallel ( NOT series ). Then you will maintain both batteries. Some maintainers have hookups for multiple batteries. But you don’t ‘need’ it
This option does work but batteries need to be same capacity and state of discharge, if not the lowest battery will bring down the better battery.
I use the battery tender model of a maintainer, the maintainer is suppised to cycle the battery to keep deposits from forming on the plates during storage. I have almost doubled my typical battery life and I use cheaper walmart batteries. The last one lasted almost 6 years, most folks get mabey 3 years. My little cheap mighty max 12v agm is over 7 years old, normally they last a couple years but they only cost 38 bucks shipped to my door. Seven years has to be due to it being on a maintainer when not in use.
I agree but can they be charged off his outboard motor charge system?? The poster didn't sound to knowlegeable about batteries so I tried to use caution.
Trickle charger and a battery maintainer are not the same. Trickle chargers just keeps the battery topped of with a low charge. A true battery maintainer runs cycles thru the battery to keep deposits from building up on the plates, if left to build up, the deposits will shorten the battery life.... The " Battery Tender" brand makes a number of trickle chargers and battery maintainer units. I also have a Harbor Freight battery maintainer that has worked well for three years, so far....my battery tender units are over 10 years and still work great.
Yes, my buddy put one in his seadoo and it has no issue charging it
Yea Im not a battery wiz by any means. just heard about the Lithum ones and was more curious then anything. I bought a new one already so im good there. This is what im thinking of getting for when the boat is put up for the winter. I have 1 battery in the boat and we have another battery we use to pump water into our campers. That one is going on 6 years old and works well. Never been on a maintainer or anything yet!. But this is what im found thinking it seems like a good price and good company as ive heard of them before.
East Penn is 20 or so miles from me. The place is huge. I go there and buy blems or batteries that were pulled off the line for testing when I need a battery. Last time there they didn’t have many, but still can buy whatever you want right there. As far as brand names I see many different labels on the batteries when I go in there. IMHO for marine use you can’t beat quality AGM.
LiFePo4 is "safer" than Lithium Ion, but still not fool proof. They will still catch fire under the right circumstances. If they do catch fire, its a fire you can't put out. So if you go that route, either have a fire plan in place aboard the vessel or switch to lead acid or AGM.
