Top 5 Questions asked by Millertech Customers

1. Can I charge my Millertech battery with an alternator?
Yes, you can, but only if your alternator’s max voltage output is 14.6 V or below. We have found there is a big difference in voltage output from
one alternator to the next. Many alternators have an external regulator where you can adjust the output voltage. When using an alternator with high
amperage output, always make sure and use ring terminal connection in order to get a good connection with no heat build up! If you want to use
an alternator, but don’t know if it is compatible with lithium, please call us and we will try to help you with your decision!

2. Are Millertech lithium batteries safe?
Yes, Millertech lithium batteries are safe. Each and every Millertech battery is built using only the highest quality materials that are available. The
lithium cells used in our batteries are UL, CE, ROHS, and RU approved, meaning they have successfully passed all safety testing. Including, but not
limited to, steel rod, puncture test, dead short test, high voltage overcharge test, 30 ft. drop test, and crush test. Our batteries have been in fires
(caused by other sources), and even though the plastic casing burned completely, our cells kept their shape and did not explode. All that being said,
we still always encourage our customers to use caution and care when using a lithium battery. This is an electronic device that is capable of high
electrical currents. The greatest chance of causing a problem will come from overcharging the battery. Our BMS system has a built-in overcharge
protection that could fail in an extremely unlikely event, so it is important to use a charger that is compatible with lithium. If at any time you have
questions about your current battery charger, please call us and we will help you evaluate your situation.

3. Can Millertech lithium batteries be used to start an engine?
Yes, but only select cranking models. Please read the description before purchasing the battery.

4. Are Millertech lithium batteries a good choice for solar applications?
Yes, Millertech lithium batteries are a perfect choice for solar, wind, and other renewable energy applications. Our batteries are completely sealed,
meaning there is no harmful gassing and corroding, making them perfect for installing in a basement or other confined environments. Most people
know a large, heavily used, flooded battery pack needs a lot of attention and continuous monitoring to keep water levels and corrosion in check. In
turn, a Millertech Life P04 pack requires zero maintenance or monitoring. Simply install it, set it, and forget it. Millertech solar batteries have 5000
cycles at 50% DOD, Flooded lead-acid (with correct care) have between 800-1000 cycles. Millertech solar batteries have between 5x - 6x the life
of a flooded solar battery, but only cost 4x the price, plus you only need to pay for installing one Millertech pack versus 5 or 6 lead-acid packs!
Efficiency: Millertech solar batteries are 98% efficient, meaning 98% of the energy collected by your panels is stored and is usable in the discharge
stage. Flooded lead-acid after 100 cycles is only 60% efficient, meaning 40% of the energy collected is wasted! In conclusion, Millertech
lithium batteries are the clear winner in solar applications. If you have questions about using Millertech lithium batteries for your solar application,

5. How do Millertech lithium batteries compare with other lithium batteries?
This is a question that we feel can only be truly answered with time. We do not know what type or grade of materials other batteries are made
with. We do know that most any lithium battery will perform ok for the first 500 cycles, but in order to perform perfectly for 5000 cycles (at 50%
DOD) and 10-20 years only the absolute best available components can be used in the manufacturing process. This is why Millertech does not buy
an (off the shelf) lithium battery from just any Chinese supplier. When creating our Millertech brand in 2015, we soon realized how easy it is to buy
a lithium battery from China. But finding one that could meet our requirements was not so easy, which is why we created our own specific spec
sheet that states every component that we require to be used in building our batteries. We use only Grade A cells from the top 3 manufacturers in
China. All Millertech batteries use commercial grade BMS’s that are over sized by at least 20A. Meaning a 40AH battery is only rated for 40A continuous
charge and discharge but is actually capable of 60A! This, of course, costs us more, but the end result is a heavy duty, overbuilt, long-lasting
product! All Millertech BMS’s are specially designed with high voltage withstand capability, (100 V), meaning our batteries can be connecting in
series up to 48V with no chance of BMS failure. Our BMS’s also have a larger balancing current rate than off the shelf BMS’s, which will keep our
batteries running at peak performance for thousands of cycles! In conclusion, we still have no way of truly comparing Millertech with any other
brand, but rest assured when buying a Millertech battery, you are buying the best product we can possibly produce, with a 5 year free replacement
warranty to back it up!
