These worked great in my Jazzy elite traveler Scooter, and we’re much less costly than the namebrand that I could’ve gotten from the dealership Read more

I bought 4 of these for some ICRA tents we use to perform work in hospitals. The fit was great. They hold and take a good charge. Read more

great price, and the convenience of getting exactly what you need at your door, but the battery only lasted 7 months with no use. Read more

Exactly as explained. Happy. Read more

I bought this as a replacement for my Jump-N-Carry 660. The old battery was over 4 years old and on its last leg. This was advertised as a direct replacement. It wasn’t! The terminals are different and I had to go to the hardware store for different style of fasteners. All in all, not that big of deal I guess? Its initial charge jumped my Corvette that had been sitting for a while. I topped off the battery charge and went to use it a month later and it was totally dead. I’ve charged it several times since, and the built in voltage meter on my jumper says it’s fully charged. A few days later it’s dead. It won’t hold a charge. I put the old battery back in and no drain occurs. Save yourself time, money, and frustration by not buying this junk! Read more
