I absolutely love my batteries, I use them for a 24v 70# trolling motor and it is amazing how long they last compared to my group 34's. After owning them for about a year, I did have an issue with one battery. It lost continuity, but the company was awesome to work with and they replaced it under warranty. Will definitely do business again.

UPDATE: So my trolling motor draws 41amps at full speed, just like the motor website says. I have used this battery for 2 trips for about 6 hours total on the water. The battery is now showing 67%. This is mathematically where it should be. Also, my motor is pushing my boat 3 mph with 2 people and gear. With my lead battery I was getting only 2 mph. This is definitely worth every penny! It will pay for itself in a couple years. The meter works perfect and takes out all the guess work of charge left. It also actually shows the amps being used as the motor is running.My deep cell lead acid battery bit the dust after about 4 years of moderate use. Like others I was skeptical about these Chinese batteries. I figured it was good a time as any to give this one a shot, since I had to buy a new battery anyway. This one only costed $60 more. As you sit there with your finger on the left mouse button trying to decide whether or not to click to buy it, just buy it. You will not regret it!Original post: Battery arrived 3 days early. Came in at 33% charged. Put on smart charger that charged at 15a. Charger shut off in just under 4 hrs right on schedule, when the battery was full. Monitor reads 100% at 13.4. I guess this is a good voltage number. Trying it out on my 40lb thrust trolling motor soon. As long as I get around 4-6 hours trolling around fishing things will be peachy. If the battery fails I will revise my listing and change my rating.

I purchased 3 of these. All 3 have the digital indicator and all have issues. 2 don't show state of charge and 1 does not show charge rate either. They offered to replace them. I chose to keep them. This does not effect rhe operation of the batteries. Only a visual indicator. They perform as described. Take a full charge and provide full discharge. Time will tell if they hold up.

Excellent battery, very compact, lightweight holds the charge very well.

The batteries work BUT be prepared to pay a preauthorization equal to the purchase price of the product. This fee doesn't come out of your account but places a hold on your funds so you are unable to access. So if the item is $300 be prepared to have $600 in your account. This hold will stay attached to your account for 7 - 10 working days. You can email them but they delay and divert any information claiming the person who handles this is either "on a rest" or "on vacation". Is this practice legal? Yes...is it ethical? No. If this happens to you contact your bank about any NSF charges this practice will cause.

for the money it's a excellent battery, i plan to buy more of them in the future

Worked through winter in my pickup to power radios and charge a solar generator.

Bought these as reserve power with solar system. Good reserve power.
