Battery Varta or Bosch

I wasn’t happy with the replacement options for the old Mercury batteries. So, I stumbled upon the Varta V80H—a battery usually used in servers—and I built a charger for it. It’s the perfect match: it has good discharge characteristics, high capacity, slow self-discharge, and it's rechargeable!

Change mine in my 2016 Golf R to this battery and it's been great. EFB shite didn't even last the first 3yrs.

I get all my batteries in Screwfix. They do Varta brand which are exceptionally good for the price.

We have a 2009 Fiesta 1.4 petrol and replaced the battery with a Bosch battery 5 years ago after the same issue. The car does a few short journeys a week so not ideal but there's no signs that the battery is about to go flat.

Yuasa are high quality. I generally get Bosch S4 or S5 as they've never let me down.

And yet my 2008 VW had a Bosch battery out the factory ????‍♂️.

Fucking thing lasted 10 years or so though. So credit to Bosch for that one!

I got ten years on a Varta in my MB 212. When I changed it out I was really surprised it was the original w/97k on it.

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.

Am luat una noua, Varta. Firma, calitate ????. Am luat-o acum 2 ani, start-stop a mers fix 3-4 luni, si acum, mai ales cand e frig, se chinuie.

I bought these both for the same exact car but both the box and product appear very different, and the bottom set ended up being ridden with parasitic drain!
