Battery Varta or Duracell

Duracell flooded lead acid would be a good choice and around $200.

I bought Duracell from Sams club. relatively easy coding with OBD11

I just replaced my xm3 batteries (they are cp1254a3 with 60mah) and I replaced it with the newer version (cp1254a4 with 74mah). No issues and more capacity.

Yep. Varta is a good battery. My battery died this year in March. I replaced it and paid 800 for a Varta battery for my dodge charger. So far so good!

Varta battery refused to die even after 5years mannn that’s a wow ..to add on I don’t use my car often i use fireblade as my daily commute for the last two years..

My XM3s went from a good 6 hour run time down to 2.5 hours in about 20 months. The last month alone has seen 30 mins wiped off them.

I went with the Varta A4 models bought from a Czech supplier called [Battex.cz](https://Battex.cz).

Varta are a pretty decent brand of battery (although their consumer AAs suck), would not expect it from them.

The older VARTA battery could only hold a charge for 15 - 30 minutes at the end. It has been in use since January 2020 and was out of use for 8 months in 2022.

ZeniPower battery could still hold a charge for a long time. Estimating 5-7 hours.

Duracell killed 6 pieces of electronics of mine over 10 years. If you paid me, I would not use them.

We refuse to buy Duracell. They leak and are awful. Never again.
