Prevention of Newly-Discovered Underlying Cause of Lithium Battery Fires Preview

In June 2024, Rob's Repairs and a Master Electrical Engineer in Alabama discovered AC ripples from a battery charger exceeding 70 volts; not its stated 33-volt DC output. Fortunately, a safety feature in one particular stairlift model prevented what could have been a fireball, such as the one that killed Tim Lilley and others.

Furthermore, the battery charger under test in Alabama voided home insurance policy. It has since been removed.
