Per Antigravity Inc.: Pre 1990's and earlier applications must update the charging system to a modern solid-state voltage regulator. Damaged or excessively old voltage regulators can over-charge and damage lithium batteries, which can cause smoking, a fire, or melting of battery. This is NOT a fault of the battery!
