## Questions & Answers

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
