Review on Optimal Battery Maintenance with Extreme Max 1229 4023 Battery Maintainer by Viterbo Dashora
Kills your batteries.
I bought this to charge 4 of my boat batteries at the same time. All these batteries are new. After the first charge, all of my batteries never went above 12.1V and charged less than 75 percent. On the third or fourth charge all my batteries are dead. That's $800+ dollars down the drain. Will never buy this again.
- Slim design
- Not as thick as other picks
