Won’t charge or won’t hold a charge

Start with the charger setup and read the charger’s lights, since the batteries have no lights of their own.

This is usually quick to sort out. If these steps don’t fix it, call or text us and we’ll get it resolved.

What to do

  1. Use the StepRanger charger, which ships as a separate item in your order, plugged into a standard 110V outlet and into the left charging port.
  2. Watch the charger’s percentage lights: blinking means charging, solid or stopped blinking means full.
  3. Check the charge port and connections are clean, with no corrosion, debris or bent pins.
  4. The battery switch doesn’t need to be on to charge. The one exception: a dual-battery All-Terrain charging both sets from one charger needs both switches on (up).
  5. If the truck sat unplugged for weeks and the charger shows full right away without charging, the pack may be too low for the charger to detect. Unplug the charger from the wall, plug it back in and reconnect it; if that doesn’t start a cycle, recover each 12V battery on its own terminals with a 12V automotive charger (take a photo of the connections first; flip back the silicone cover, and if the wiring is in the way, unscrew it from that battery with a Phillips screwdriver and screw the bolt back in for the clamps), then try the StepRanger charger again. The full steps are on the battery page.
  6. Plug in after a day of use and let it charge overnight.

Still not working? If a battery bank still won’t reach full or holds noticeably less than it should, call or text us and we’ll get it resolved quickly. We’ll work through it with you by phone or a quick video, and if a part is needed, we ship it.
