Optima red top battery maintainer
My red top died so I bought another.
I've read I will need to keep a maintainer on if I won't be driving for more than 21 days at a time.
Can you all give me a direction to go in finding a maintainer for my optima battery? I had one on there but I found the instructions and read it is for a liquid lead battery only so I pulled it off.
Thanks corvetteforum.

A Battery Tender or similar is what you are looking for.

Costco had these recently for under $40.
Also, google restoring AGM style batteries. Many times you can restore these batteries when they seem to not hold or take a charge. Most of the newer chargers have a tough time charging AGM batteries when they are over discharged but it can be done.

I have the same battery, a little over 6 years old and use a Battery Tender Plus. It does a great job keeping the battery fully charged.

You absolutely need need a maintainer on the red tops. I have killed 3 of them letting them sit for a month or so in the car, go to start - Dead. I have a $20 or so one from harbor freight that has the quick disconnects I mounted to the top posts. I plug it in every time I get home. Has worked great for this past year.

Thanks for the responses.
I'm trying to attach a pic of the one I was using(similar to the harbor freight one). It has worked for me; I just got lax in attaching my charger, then we had the two big cold spells(yeah, it's all relative!)so my battery went kaput.
I've had the pictured(I hope)charger on since the end of December until two days ago when I found the paperwork that said only lead battery use.

Little pricey but I have this charger, i really like it. has several modes for different types of batteries (one mode is for AGM), and has status lights to show you exactly what it's doing right now. the manual gives you a pretty in depth explanation of its logic and modes
