Why is the battery pack on my Sterling DIAMOND not charging?

  Mark KellyJul 26, 2025
  If your Sterling Scooter's battery pack isn't charging, consider the following potential causes: * The battery pack itself may be faulty, requiring replacement. * There could be a fault with the charger, which would also need replacing. * Check for any damage to the charger loom or plug; if damaged, contact your local mobility dealer. * Ensure all connections are secure by checking plugs and looms. * Try a different wall socket to rule out a problem with the outlet. * Examine the charger's mains plug for a blown fuse and replace if necessary (after unplugging from the wall). * If there's a button on the battery pack, make sure it's pressed in after switching off the scooter.

Why does my Sterling Scooter have a shortened range?

  cgarciaAug 3, 2025
  A shortened range on your Sterling Scooter can be due to a couple of reasons. First, ensure the batteries are charged for at least eight hours. If the problem persists, the batteries may be weak and unable to hold a charge, in which case you should replace the battery pack.

  Gabriel EvansAug 11, 2025
  If your Sterling Scooter indicates a high battery charging current, it could be due to faulty batteries, which would require replacing the battery pack. Alternatively, ensure the scooter is switched off during charging, as leaving it on can cause this issue.

  Jon MillerAug 18, 2025
  If your Sterling Scooter isn't moving, here's what you should check: * Ensure the brake-release lever is engaged. * Charge the battery pack if it's flat. * Make sure both the scooter and battery pack are switched on. * Verify the battery pack is correctly clipped in. * Unplug the charger. * Reset the circuit-breaker button if it has popped out. * Inspect all plugs and looms for disconnections. If these steps don't resolve the issue, there may be a control system fault and you should contact your dealer.
