• The KL 1208 is a traditional charger, not a modern "smart" maintainer. Leaving it on "Fast" charge overnight can overcharge and "cook" the battery. If you must leave it unattended, ensure it is on the lowest "Slow/Trickle" setting, but ideally, use a timer or monitor it.

• Likely cause: Battery is too hot from heavy use, or ambient temperature exceeds 104°F.
• Solution: Remove battery. Allow to cool in a dry room (not a refrigerator). Try again after 1 hour.
