### ⭐⭐⭐⭐⭐ Power to the people
*by S***E on 8 April 2021*

Can’t speak for longevity - only just started using them but I have been a fan of Varta batteries for years. These batteries reflect the same build quality as the market leader D*L but are fantastic VFM. I don’t normally buy in such large quantities - but you get to the point when you get fed up of not having the right size battery in the house when you need one
