Harbor Freight once sold a 6 volt battery charge that worked great charging optima 6 volt batteries. My 6 volt charge no longer works....Not so great.

Check out the chargers at "no.co". Four letters with a dot in the middle. Also available on amazon. I have two for maintainers, but also charge with them.

No Co seems expensive. Check out Battery Tenders on E Bay.

Frank, I bought this one several years ago it does 6 and 12V. Battery extender SC4 model BE01250.

Has a rate selector 3A maintainer or 15A rapid charge, battery type standard, AGM or gel. If your not paying attention it even has a revered clamp indicator. I think I bought it @ O'Reilly auto.

I use, and recommend that slow charger that Petehoovie posted. I have connected the battery hook up directly to the battery posts and run the pigtail under the floor mat. Can't tell it's there and if I decide to top off the battery charge I just plug it in. A handy set-up... Chap

Wal-Mart has a good charger. 6 and 12 volt with a battery maintainer and will charge Optimo batteries, Was originally a Shumacher brand but now has a Wal-mart label.

Get a Schumacher charger for basic all around charging. They are cheap. Good charger. If lucky they can be found at a garage sale or auction.


optima's need to be charged not tendered other then running (gen). Charge them twice a yr, 10-14 yrs, 2 batteries. Great battery.


A optima rep has been on there and has said treat it like a battery. It does not not to be tended.

Save a battery charger maintainer. Really good unit. not only charges but maintains. Also this unit can bring batteries back from the dead by cleaning the plates. Can be got in 6v 12 v and 24. I've got a 6 and also a 12v and use them all the time

US unit too

We use the "Battery Tender" that is adjustable for 6 or 12 volts as a maintenance charger. They are readily available. We use them for both conventional lead-acid batters, and for the Optima, as well.

I worked for a battery manufacturer a few years back. Midtronics for battery
analyzers. Schumacher for regular chargers.
I have both Noco Genius and Battery Tender Jr for maintainers. I'm doing a
"trial" on those two to see which one is better on Optimas right now.

HF has a small unit that does 6 and 12 and AGM, GEL, and STD.
It was less than 25 with a coupon.
Works great.

search on 6/12 volt on google, they are out there. Try Tractor Supply. I have a 6volt battery tender and a 6/12 craftsman that I bought when sears was still going.

post 13 on the thread. I'm sure if you have questions they can be asked directly by pm, concerning the optima battery. Great battery in my thinking.
