The 4001 Heavy Duty Jump-Starter features an exclusive Voltage Spike Protection and Automatic Reverse Polarity Protection safety features. Combined with a remote start switch, for the ultimate in operator and vehicle safety, the unit powers the output leads only when a correct connection is made, avoiding costly damage from starting errors.
This Model No. 4001 is designed to be used with (2) installed Group 31 batteries (not included with your purchase) equipped with top-mounted, threaded stud terminals, with a starting capacity of 900-1200 CCA each. Smaller batteries can be installed, but this will likely result in decreased starting power and care will need to be taken to ensure that the batteries are properly secured in place.
When installing flooded (wet cell) batteries, use batteries with sealed top or with screw type flush fill caps. This will help reduce acid leakage should the unit be inadvertently laid flat or turned over.
A high quality battery emits fewer gases as it recharges. Using a high quality battery will extend charger and wiring life. Battery acid and petroleum resistant wiring is used in this unit. Battery fluid level (wet cell batteries) must be checked every 30 to 45 days.
