  • Great Battery for Older Luxury Cars
Style: Group 49
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. ... show more

I recycled my old battery at a auto parts store I will buy this battery again. Perfect fit and the k you Amazon for a good price for the auxiliary battery. ... show more

  • Excellent Battery and Service at a Great Price!
Style: Group 47
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! ... show more

  • Won't hold a good charge
Style: Group 47
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. ... show more

  • Perfect replacement for 2016 Dodge Challenger
Style: Group 94R
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. ... show more

  • Works perfect and is much cheaper than in store
Style: Group 48
I put this battery in a 2022 Mitsubishi Outlander and it works amazing. This one was literally about $150 less than what we could have bought at an auto parts store! I have had it for about 2 months now and (knock on wood) it is still working perfectly. Highly recommend.

  • GREAT OEM REPLACEMENT BATTERY

Great OEM Replacement battery for my E84 BMW X1! Even though the first unit I received was defective, the seller promptly provided a replacement and it worked like a charm! It provides plenty of charge and fits perfectly in the spot!
