I’ve had two duralast batteries in my 02 24v and they’re so old I honestly can’t remember when I put them in. But I’d say they’re about 6-7 years old, probably more. When those batteries finally give up I’ll definitely be getting new duralast batteries.
I recently got a Duralast Platinum battery and it has proven to be very good so far
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 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've also had great luck with AutoZone's Duralast Gold/Platinum batteries and they have better warranty than most others as well.
My last battery was a Duralast Gold and it lasted 7 years.
Since the battery weighs ~40 lbs this isn't really a significant weight change from front to rear so I've no idea if the car handles any differently. Would I recommend this mod? Probably not as it's not cheap and has no real performance advantage and more crazy than anything.
I installed a new battery but now the car won't start or turn over.
Currently I actually own a 2005 V8 and it has been just short of a nightmare to maintain. First was the battery($400) then the headlights($200) then the Thermostat($900), then the horn($80) then timing belt, water pump, stripped drain plug, etc all within a year.
we see many 2 year old Duralast batteries that have failed.
