Works great so far will find out of it still works great in next few days when I have to mow the lawn
Quick shipping quality product!
So far so good, came fully charged ready to go. For a TTR230. Will update later if there are problems. I treat my batteries well. Bring them in the house over winter when not in use and charge them periodically. So it would have to be a manufactures defect or poor quality if it doesn't last five years.
Looks good, came fully charged. I stalled it on my 2022 honda navi 110. Time will tell how good this battery is. 1/3 price from the dealership.
Quick and quality
Recently purchased new Mighty Max Battery 320 CCA for a Simplicity Regent 23 HP Briggs and Stratton engine.
I received my new battery replacement today. I want to compliment your outstanding customer service. II actually was a pleasure working with your company. Your warranty coverage is excellent and easy to work with. Thank you again for your great service.
Battery came well packaged and fully charged. Terminal nuts & bolts are included. It fits my driveway grader perfectly at half the price of the OEM battery and a longer warranty. I'd endorse buying it.
Home Depot did a good job ordering it. USPS was about three days late delivering it but it all came out fine.
