EnersysCyclon Genuine 0819-0012 6 V 2.5 Ah D Monobloc Sealed-Lead Acid Battery

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.

This replacement battery worked great on my old lifecycle. I was able to install it myself, and save some money. Getting access from the cover was the hardest step. After that installation was easy. Make sure you watch the battery polarity! Highly recommend.

Very good battery. Exactly like original and work perfectly. Good price.

Used to replace the battery in my Life Fitness 95 cycle. I did need to charge the batter with a 12 volt charger. But once it was fully charged, my trainer has worked like new.

Perfect fit and easy replacement for life fitness CLSX elliptical.

Battery arrived covered in the white crusty acid all over it that you get on a battery after you left it in a flashlight or device for several years.
