Works perfectly
I purchased this to replace a battery in my stair climber, and it worked perfectly! So far the battery quality has been great and I’ve noticed no issues. It was a good price and seems to be a good quality. The stair climber fired right up when I attach the battery. I would recommend this item and I’m very happy with it.

Replacement Battery
Battery was easy to replace and way cheaper than a new machine. . .

The right battery for me
Perfect replacement for the battery in our Life Fitness 9500HR that was no longer charging. I swapped this in and the elliptical immediately started working normally. My only complaint - the stickers on the bottom of the battery partially cover the screw holes so I had to peel them back.

It lasted 4 years
I used this battery to replace a failed battery in a stationary exercise bike. The purchase date was January of 2022. It worked until September of 2026. So I'd say it wasn't too bad. It was good enough that I bought another one to replace it again.

Battery lasted 6 years for me..
I bought this battery back in Feb 2020 to replace a dead battery on a Lifecycle 4500. It has worked well over the past 6 years, just dying about 3 months ago. It seems like these batteries are a mixed bag as some.may fail sooner than others. I guess I must have lucked out.

Replacement battery for recumbent bike
The hardest part of replacing the battery on my old recumbent bike was getting to it. I went on YouTube to find out, went to the hardware store to buy a battery operated drill with correct bits, unscrewed 19 screws, replaced the battery (which works great) and put it all back together. It works perfectly! Not bad for this 72 year old widow!

Fixed up an Octane 350 elliptical machine with this!
This is the correct battery for an Octane 350 elliptical machine. I got a great deal on one, but its battery was fully dead. After a long charge, I found that one of the three cells couldn't hold a charge. So I looked this up and got the thing open so I could swap out the battery. The elliptical is running beautifully now! So, yep this battery does everything it's supposed to, right down to having the correct placement of screw holes to attach to the machine's frame.
