BatteriesPlus review: They don't honor warranties

Purchased a new Duracell 30LA battery for my 2017 Harley Davidson Road Glide on 1/23/2024 from the Ft Myers FL store. On 10/15/2025 I returned it because it no longer had the cranking amps under load to properly start the bike. This particular battery carries a 2 YEAR FULL REPLACEMENT WARRANTY. I have purchased many of these same batteries in the past for my Harleys over the years and never had a problem until now. Chad, the guy at the counter load tested my fully charged battery and it tested at 13.1 volt and under load it tested at 313 cranking amps. This is a 400 cca rated battery. That's 87 cranking amps short of rated capacity. At that point Chad refused to honor the replacement warranty further stating that loss in capacity needed to be greater than 20%. I'm not really sure where Chad got his math education but 20% loss is still 320 amps and mine tested 313 amps. That's not enough to start a Harley Big Twin so essentially I now I have a $219 completely worthless battery that is ironically still under warranty. Apparently you don't get what you pay for at Batteries Plus anymore.
