Location: Mauston, Wisconsin | Its not true that AGM's last longer, they are just easier for the average fisherman to use. Every battery has a design life (3-5 years) and cycle life (100-200 full discharges) - once it hits ~10.5V its fully disharged. They also need to be recharged as soon as possible after discharge.....DO NOT LEAVE THEM SIT IN A DISCHARGED CONDITION!! Leaving them even partially discharged for days or weeks is a recipe for new batteries - the typical manufacturing warranty will not cover this, meaning its failure to follow the manufacturer's instructions a.k.a abuse!
Battery resellers love you guys who abuse batteries, because you always blame the battery and the manufacturer! Going and buying another manufacturer's product will not fix your problem.... The vast majority of battery failures are related to improper charging.
Have fun!
