Iíd be willing to guess that it works just fine with AGM batteries with those results.
Iíd NEVER, EVER buy another Deltran/Battery Tender product after dealing with their customer service folks . I tried to get warranty service on a 10 month old unit, and they told me there was a 35$ ďhandling feeĒ to process my replacement, plus Iíd have to send the old unit to them at MY expense. To be clear, that was 9$ more than I paid for the original unit. Their warranty is a joke!!
