Their website is really light on details about mAh[0], but Duracell are even worse[1]. I’ve found a comparison website, but no idea where its getting its sources[2].

Looks like VARTA is around 2400mAh and will last around 5-7 years, whereas Duracell is around 2700mAh and will last around 7-10 years. But let’s be realistic here, no battery in the world lasts more 2 years without needing to be switched out. Definitely not worth staying with Duracell.

Why is babushka a Super Saiyan?

I’m using AGM Varta battery for my car for 4 years. For now it is working fine.

I saw a Project Farm video where they tested various AA batteries, alkaline and lithium.

One of the tests was how long each battery could run a fan with a constant energy draw and Varta Longlife got the worst score by far.

Those had a made in Indonesia label though, I don’t know if they have different plants in Germany with better specs under the same name.

They even have lithium-ion batteries in AA!
