## Questions & Answers

**Q: Hi - I am wondering if this battery is the same as the 0819-1006 Sealed Lead Rechargeable Battery for my LifeFitness LifeCycle? I need a replacement.**
A: It appears to be the same. I was afraid to order the battery at first because the number was different, but when I looked into it, it appeared to just be the updated version of the 1006.  The battery fit into my lifecycle machine and has worked great since.

**Q: Will this fit the LIfeFitness 95ri recumbent bike?**
A: Yes, the 0819-0012 battery will work for the 95ri bike..

**Q: Will this fit a older Lifecycle 9500 upright bike?**
A: If that is the size and type battery called for by your bike manufacture it will probably fit - my experience is that it will not last very long as my although on constant trickle charge died with in two months

**Q: will this battery work with life cycle model 9000?**
A: Take your bike cover off and look at the battery. Compare the voltage, size, connector  and amps.  I have a 9500HR  and it worked for me

### ⭐⭐⭐⭐⭐ LifeCycle 9500 HR battery replacement/ worked fine with no glitches

### ⭐⭐⭐⭐⭐ Replacement for Life Fitness C9i exercise bike
*by K***S on August 17, 2024*

Needed a replacement battery for my LifeCycle C9i. The display would not light up. This can happen with an old battery (like mine) or if you don't use the bike for a number of months (like mine). Replacement requires T20 and T30 Torx screwdrivers to remove the right side of the shell and one pedal. You will also need to remove the front two screws from the left side shell to allow access to the battery. You may also need a T30 socket if the pedal screws are hard to remove. You will need regular screwdriver to remove the battery screws and a pair of needle nose pliers to remove the battery connectors. Be sure to attach the red lead to the + terminal and the black lead to the - terminal. The replacement is straight forward, if you are handy and have the tools. If not, call a service tech. My original battery was a 0819-1006, but this is identical in configuration and works just fine. Same voltge and Ah rating.
