Battery OPTIMA or Duralast

The battery you want is an AUX18L 20ah battery. I used [This battery](https://www.autozone.com/miscellaneous-non-automotive/power-sport-battery/duralast-gold-etx18l-group-btx24hl-agm-ready-to-ride-power-sport-battery-340-cca/350084_0_0?spps.s=4782) myself a month or so ago, it is an ETX18L and it has been working fine.

I put that same Optima in 6 years ago (to the month!). Mines still fine knock on wood

Red optima battery on my 93 integra 10 yrs old still starts.

FWIW, my post is the top one, I did not go with an OEM battery after reading through other threads where users had issues finding one in stock and instead went with the Optima YellowTop that was recommended on their site. I have had zero issues.

I just replaced my OEM H5/LN2 group 47-sized battery with a Duralast Platinum H5-AGM Group Size H5/LN2 680CCA battery. After having my mechanic change the settings in the ECU from EFB to Fleece for battery technology, 60Ah for rated capacity and set the date of install for the last 8 digits of the serial number, all seems to be fine. It fits the OEM position and cover perfectly.

I recently switched to an Optima Red Top 35 Series which has 720 CCA.

Used redtops for years. Had a couple go bad, but 3 year free replacement warranty solved that.

Optima isn't nearly as good as it used to be. I've owned a lot of their dry cell batteries and they've gone to **** over the years. They don't hold up well to this kind of use, and if they drop below 11V they **** the bed.

Once Johnson Controls bought them, they've become worse and worse.

My optima failed after 1.5 years
