I left one car off tender for a short time and now need to get a new battery

Better safe than sorry with a newer computer controlled car is just spend the money and get a new one.

Hello, I noticed your conversation regarding our batteries and wanted to offer some assistance. You do not need a special battery charger for our batteries. Normal battery chargers will work just fine, although it's important to clarify that our batteries are lead-acid batteries in a SpiralCell, AGM design. “Gel” or “Gel/AGM” charger settings will not fully-charge our batteries and could damage them over time.

We do recommend a maximum charging rate of 10 amps, 13.8-15 volts for regular charging. For float-charging, we recommend a 1 amp maximum rate, 13.2-13.8 volts. If anyone has any other questions about our batteries, I'll do my best to answer them.

Here in California, You CANNOT buy a 2 amp trickle charger such as the ones made by Deltrans that will work on an Optima battery. You must buy one off E Bay to get one and have it shipped here. If you try using a regular 2 amp charger on the optima, It will stop charging after a minute or two & say it's fully charged. Check E Bay & read some that are for sale and they will say NOT to use on an gel or dry cell battery. I had to buy one off E Bay to keep mine charged. California does not want people charging them here.

If you have a newer battery charger that is meant to charge an Optima you should be all right.

I am not against Optima batteries but what I am saying is they are different than the lead acid batteries
that have been around for over 100 years and need to be treated differently.

I just bought 3 new Deltrans chargers, I replaced the ones that were 7 to 8 years old that I had been using. After hooking them up, I would notice the 2 cars with the Optima's were turning green in 2 to 3 minutes. After checking everything out, I had found out California has banned them. I had to return the ones I just bought and buy 3 from E Bay , ((from a seller back East)) that specify the use with the Optima. Sure enough, as soon as I put them on, they stayed on over a day. Are there other States that have also banned them, or is it just California ?????

Don't know if it was true then or now, but most are probably made in different color cases and sizes in one of a few manufacturers

I have had good luck with Interstate batteries, and have bought a lot of batteries from Sams club, which use to have great warranty exchange program.

As I posted before I purchased a new Battery Saver pulse battery charger
It is a battery charger and maintainer and is too work on all types of batteries. Hope it does what they claim. Like it so far, have charged my deep cycle battery in the enclosed trailer to a full charge and have it on the Imperial right now.
