Another outstanding Millertech purchase
After I purchase the trolling motor batteries I decided to upgrade my starting battery with a dual purpose also from Millertech. Thrilled with the performance of all 3.

MillerTech 12v 100ah Starting Battery.
I ordered the battery over the 4th of July weekend when mine died. They shipped it on Monday and I had it by Wednesday. I was thrilled to get the new battery and be back on the water this past weekend.

Excellent communication and battery
Communication started the minute order was submitted. Battery was delivered on time. Battery came with approximately 80% charge. Was able to quickly connect with the app and fully charge the battery. Have used it one time so far to power electronics on a bass boat. Very pleased.

Peace of mind
The time has come to upgrade to new lithium technology and with so many options available, Millertech stands out for checking off all of the boxes…. From size, weight, warranty, pricing, answering questions, etc…Was tired of replacing expensive AGM batteries every 3 or 4 years… and at the end of day if there is anything I can do to avoid a bad day on the water or a ruined trip… I’ll do it. Millertech and their reputation made the decision easy. Purchased 3 100ah dual purpose. Arrived on time and perform as promised. Warranty alone makes this a worthy investment and brings peace of mind. Couldn’t be happier.
