Went to replace my battery today and the guy pulled out three Varta boxes, Black, Blue and Silver, and asked which one I wanted like I was supposed to know. I asked what the difference was and got a half answer about cycles and warranty that didn’t really land, so I said I’d come back. Now I’m trying to figure it out properly and found a Helpful guide to choosing between Varta Black, Blue and Silver batteries that actually explains the tiers in plain language, which is more than the shop managed. But I’d still like to hear from people who’ve actually bought these. Is the Silver really worth the extra for a car that does mostly short trips, or is that just something they say to push the pricier one? And does the Black hold up in this heat or should I be looking at the higher tiers regardless of budget?
