Charger was purchased new 2 years ago, if you know you know, best chargers made. Have had one on every boat and have never been let down. My current (no pun intended) batteries are from 2018 and 2019. The dual pro profiling is no joke, they keep batteries alive longer. Selling cuz i am downsizing.
these are programmable by dual pro for lithium.
