I’ve been running the Mighty Max battery in my 2006 Mercedes S430 for a few weeks now, and I honestly couldn’t be happier. I was a little hesitant at first because it’s priced lower than some of the big-name options, but it’s held up exceptionally well, even in eventfull weather and after sitting for a few days. Cranks strong every time. What really impressed me was the fitment. It dropped right into place with no modifications needed, which can be tricky with older luxury cars. Voltage stays consistent, and I haven’t noticed any electrical hiccups or drain issues since the swap. For the price and performance, I definitely recommend if you're looking for a reliable, budget-friendly battery without cutting corners.

Exact fit and is working perfectly. We couldn't be happier and more satisfied if we had paid for a battery costing 2-3 times more than this one. It arrived fully charged, carefully packaged, and 'overnight', which was much appreciated and necessary for the important errands and appointments we needed to attend to the next day. Outstanding in every way! I would not hesitate to buy this battery brand again!

Bought as a replacement battery for my Challenger. Fits in the battery spot no issue. Tested with a couple different battery testers after being fully charged and shows well over 850CCA. It has been in the car for 6 months, in what can best be described as a Sunday driver/Show car. It has held a charge, and always cranked the modded 5.7L motor without fail. I also have a 4,000 watt sound system, and run a second battery to help with that. With this battery, there has been no light dimming, and no worries about leaving me stranded.

First off the battery was over 7 months old setting on the shelf that they sent to me. I have a battery monitor. It's coming up on 3rd week having battery. I put a good charge on the battery before installed in vehicle. Every night I would lose more percentage. This morning 71 percent is all it would hold. A brand new battery should not lose that much during the night. It started with like 96 percent the first night and just keep found down from there. The volts have went down to 12.11v during night. I have no parasitic draw. My old battery is still good just replaced for maintenance. I have even unhooked the battery from vehicle to make sure it wasn't a draw. Still went down on its own. You can just tell it's a cheap battery, worth stickers thrown on it. There's a reason it so cheap. I thought it would give it a try. Don't care if it's a cheap battery. If it's loosing that much every night it for something wrong with it. And it just gets worse every day. And my alternator is working properly also. I have all the monitoring information to prove it. Hopefully my prime returns it's worth no problem. And i move on with a life lesson. I would not suggest waist time or money on this battery.

Subaru wants one to use their "new" battery with install and new holder over $500.00 This one arrived, ease of use for install a 6, put in with a battery charge in place, size was correct, quality to early to tell. Well worth the test. And if you hesitant get yourself a small jump starter for $40 and you are still WAY ahead.

Packaging and battery look great. Waiting to install but for the price it seems to be a great deal. I got this for my 2021 Nissan Kicks

Item arrived on time and in excellent condition. This was a perfect fit for my 2014 Chevy Volt. I bought the group 47 / H5 version. As soon as I connected the negative up, my Volt horn alarm sounded. It started my car immediately and I was finally able to put it into reverse and drive and have it start moving. I plugged in the EV charger and the car started charging the high voltage pack. (It wouldn't start charging while I had the original bad 12v battery in there. If you are installing into a Chevy Volt, remember to connect the battery exhaust tube on the right side of the battery So far I am happy with this purchase. Give me 3 years to report back if anything goes off the rails.
