Dual Purpose Batteries LiFeP04 are quickly becoming a popular item that many enthusiasts demand. Our team of Engineers and Technicians are a very aggressive group and were not willing to take a backseat on this trend. This battery has enough cranking amps to start even the largest engines in the industry, plus they have enough reserve capacity to power multiple power hungry graphs for 8 plus hours. These Dual Purpose models will change the way anglers think about there power needs forever.

(KEY FEATURES)

10 year Industry Leading Warranty

BCI Group Size 31

Bluetooth activated to connect directly to our MillerTech App. The MillerTech App gives you in depth, real-time data, taking the guessing game completely away. Power with Confidence!

Custom molded, heavy duty, re-closable battery case. This means if you ever have an issue with your battery no matter is it in year 5 or year 15 we will always have easy access to repair any defective parts. This custom case also has convenient hold down strap grooves molded into the side corners helping to keep your straps seated securely in place.

Large heavy duty battery terminals ensuring there is no heat buildup when your application demands maximum power!

The Sport Series Marine batteries are all sealed with a thick rubber gasket along the lid connection point. This means they are Marine approved IP65 rated. A completely sealed battery case will cause condensation, so we build them with a marine grade Stainless Steel breather vent. Our vent sits on the top of the case unlike some others where the vent sits down inside catching rain and dirt.

A 10 year warranty is not a commitment we take lightly. We believe a warranty is only as good as the company and the people standing behind it. We do realize there is a certain uncertainty about how a company will handle a warranty claim if the need should ever arise. With MillerTech our hope is that the customer will have no doubt in his mind about how we will approach warranty claims. Our company is built on a Golden rule principle that we have inherited from many generations of Anabaptist forefathers. We pledge to always put the customer and his needs first.

The Ironman logo is a serious distraction.
Color: Black/Black/Digital Neg Display
A wonderful watch, with one serious problem: for me at least. The big Ironman Logo at 9 O'clock position is a very confusing element in this otherwise nice design: it competes and completely overwhelms the two Hands read-out. The Logo can give you misleading time: because one confuses it for the Minutes Hand. In a hurry, one is bound to make such mistakes -- call it a human error, but this one can have serious consequences, i.e. reading the wrong time. I have a couple of digital Ironman watches, and Timex does a great job with their usability and quality. This watch is of very high quality too. I love the dual display, and it is very practical. All this watch needs is a removal of the white Ironman logo. That would also make reading the digital readout easier. Please leave the Minute and Hour hand to their exact shape/design -- i.e. don't mess it up. This watch has the potential to be a much more user-friendly watch. I hope the next gen has a simple dial with hopefully even an easier digital readout. Please color the 'Start' Button Orange. I love the Orange Seconds hand. Overall: Size is good. Strap is good. A very good concept digi-ana. Very practical.

Lemon
Color: Red/Black/Digital
I love the watch design, but the watch itself is a complete lemon. I have bought this watch three separate times and it still does not work properly. The first time, the hour and minute hand swung freely in the watch. I returned it directly to Timex. The second time, I bought from Amazon thinking the first watch had defect and the return policy with Amazon is less cumbersome than Timex. Right out of the box, I set the date/time and played around with the features of the watch that I most commonly use, most the chrono function. When I press start on the chrono function, the watch completely blacks out and resets itself somehow, meaning I have to set the date/time again. I sent the watch back to Amazon for a replacement. When the new watch arrived...same issue...the watch resets itself every time I start the chrono function. Very disappointing. Come on, Timex. You are better than this.

Unfortunate
Color: Black/Black/Digital Neg Display
It’s a cool new design but the night light button stopped working within a month of buying it. Shouldn’t happen with a 150$ sports watch

Garbage
Color: Black/Black/Digital Neg Display
Absolute garbage. The date that came up was from 2022. Most buttons did not work. Once you got into changing the time, etc, the watch locked up and would not get out of 'timer' mode. The watch lost 10 minutes in three hours. Do not purchase.
