HUB BATTERIES

Normal battery life in the hub is 400 hours of actual ride time. Use #357 or EPX76 Silver Oxide type batteries and always replace batteries in pairs. Alkaline type batteries give shorter life and poorer performance. NOTE: After replacing batteries in the hub you need to Learn the device codes. See computer setup 5.

BATTERY REPLACEMENT

-Unscrew the plastic battery cover. Use a spanner wrench or bench vise opened wide to get it started if stuck. There are O-ring seals that can cause the cover to resist the start of motion. The threading is normal right hand.

-Remove the battery pack. A small screw driver can be used back and forth between the to ends to start to lift it out.

-Pop the battery out by bending the plastic retaining tap back and pushing the batter up from the bottom.

-Check that the electrical connector tab from the inside of the hub is perpendicular to the

bottom of the battery pocket. If the tab gets bent, gently press it back to perpendicular with a non-sharp tool.

-Slide the battery pack back into position along the center core. As the battery is engaged a small increase of resistance to installation should be felt as the electrical connections are made.

-Thread the cap all the way back on.

-Replacement O-rings and battery packs are available from Saris Cycling Group.
