Battery OEM Mazda or Varta

Our household got its first EV earlier this year, mainly for the daily 20-25 km commute form my SO, and it’s been the best car purchase we’ve ever made (only bested by my 3, which made it to 10y w/o problems this year). That “small battery” that once worried us (or more like we intentionally went with the smaller offering)? Barely a drawback - in the summer, a single charge lasts a whole week. This EV has become our go-to for short trips, and while cutting running costs by 2/3 was a big motivator, it’s now just a nice side benefit. I love the torque and started to love the silent driving. especially in a traffic jam.

Salut, am C class diesel din 2012 cumparat acum 2.5 ani. Cand l-am cumparat avea bateria originala, Varta cu logo Mercedes. Am luat fix acelasi model de baterie de la Varta, dar fara logo Mercedes, a costat 850 lei, mi-am montat-o singur. Am considerat ca daca cea originala a tinut 11+ ani, merita sa iau acelasi model.

I’ve had good luck with the VW OEM Varta batteries.

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!

The Mazda OEM battery only lasts 3 years it seems. I have a 2021 and just changed the battery for similar reasons. It still started with no issues but it was pretty weak and was immediately noticeable after installing the new one. If you can afford it, the extra money for an AGM is worth it.

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

The only issues my wife and I have had on our 2021 CX9 and 3GT are dead battery issues. And we had dash and reverse cams fitted, which run and film continuously. If our street is busy, they can run the battery flat within 2 days.

Mazda OEM batteries known for underpowered and short shelf life. If you are in any kind of extreme climate for more than one season, there's a likely chance of failure.

162km at 42% battery is still kinda poor for 2025.

My 2025 CX-30 battery is already showing signs of dying but I bought the car in April but then had surgery in June and only went back to work today so it sat for long periods and I do leave my dash cam in parking mode. It might come back some after being driven more or it might not.
