If your battery popping up, disconnecting, not fully seated, or has come unlatched while riding, this article will help you resolve this issue.
- Visually inspect battery housing: Check to see if each bracket of the battery housing is flush to the frame and properly aligned with the others.
- Tighten Screws: Using the proper screw driver (too big or too small, you may damage and strip the screw making it very difficult to remove or tighten) make sure the screws are not loose. Please carefully tighten them until it is snug. Note: If you have removed screws and are re-installing: If a screw is not going in, DO NOT FORCE IT, it is likely not aligned or a cable/wire is in the way.
- Grease Latch Mechanism: Oil works better and lasts longer than WD40 (as shown here)
4.Grease Silver Spring Loaded Pins: Add a little oil or a little WD-40 to these 2 pins located on the right (circled in red below) and then push them in and out multiple times to work the oil in.
5. Remove 1 of the Spring Loaded Pins (if necessary, both can be removed): Using channel locks or pliers, it should slide right out. Removing 1 of these spring loaded pins will lower the upward force on the battery. Occasionally the springs are too stiff and pushing up on the battery too hard.
6. Ensure the Terminal Nuts are Secure: It is not commonly the cause, but you can also verify that these thin nuts (circled in blue below) are snug and not loose.
This should resolve the issue in most cases. If it does not, please check the right side of the middle battery compartment panel. If it is not well aligned (Picture 2 below shows the middle and upper battery compartment panels and how they should fit together), then a brake cable, shifter cable, or wire may be in the way under the panel, causing the issue. These cables and wires should run on the right side of the down tube. You should be able to make most adjustments needed by only removing the upper battery panel.
The pictures below show the 3 panels of the battery compartment.
- Upper battery compartment panel (with locking mechanism, 5 screws holding it in place)
- Middle battery compartment panel (the long piece the battery rests on, some models/generations, this will be part of the aluminum frame)
- Lower battery compartment panel ( 3 screws holding it in place)
