Intended Applications
Use this product only to maintain the charge of a ooded lead-acid battery.
TO PREVENT BATTERY DAMAGE:
Do not use on gel lead-acid or AGM (Absorbed Glass Mat) type batteries.
Note: Check battery voltage with a multimeter before use.
The Battery MUST be fully charged to at least 12 Volts.
