Verify battery condition before charging; do not attempt to charge visibly damaged or leaking batteries. For best battery life, follow manufacturer guidelines for charge acceptance and avoid prolonged storage at low state‑of‑charge. When charging different battery chemistries, confirm the charger’s selected profile matches the battery type.
