Review on 🔋 Deltran Battery Tender 12V Battery Charger, Selectable Chemistry (15A/8A/2A) - Model 022-0234-DL-WH by Scott Decoteau

I bought this charger a while ago and have been charging batteries and such. I noticed my diesel pickup revs a bit slower when starting, so I put my tester on the batteries to see if they were good or not. My battery tester said the batteries were fine, but I just didn't believe it. So I connected the charger to separate batteries and found that one battery was 30% charged and the other 40% charged, which isn't nearly as good. My battery tester misled me and I think it may be because these batteries are AGM batteries. The tester was always right with lead-acid batteries. I'm very glad I had my own charger. This is amazing stuff!
