Marathon Pow'r Pak LD
The Marathon Pow’r Pak LD is an integrated valve-regulated lead acid battery and charging system designed for 24 volt electric walkie pallet trucks with loading capacities of up to 4,500 pounds. The Marathon Pow’r Pak LD houses a “smart” HF charger complete with auto stop/start capabilities and four 6-volt Marathon Element bloc batteries connected in series to provide a 24 volt system.
Features & Benefits
Marathon Element batteries mean reduced maintenance. Most of the expense, time, and safety concerns typically associated with conventional flooded battery maintenance are reduced under normal operating conditions, including cell watering, acid equalization, acid spills, corrosion and waste treatment systems
Automatic On-Board Charger
Because the on-board Delta-Q charger used with the Marathon Pow’r Pak LD is fully automatic, operator guesswork is eliminated. Unlike other chargers, this charger uses the precise “I-E-I” charge profile to correctly determine the proper recharge time required. Charging begins with a constant 25 amp start rate until the batteries reach the appropriate gassing voltage. At this point, the charge adjusts to a constant voltage stage to minimize gassing, finishes off with a constant current to ensure a quick and complete charge, and finally shuts down automatically when the batteries are fully recharged. International versions are available.
With the Marathon Pow’r Pak LD, battery charging is simple and efficient, offering operators freedom from the charging limitations of conventional flooded batteries. Operators can take full advantage of extended breaks or downtime between shifts to opportunity charge their Marathon Pow’r Pak LD, which translates into better use of operator time and increased productivity. Optimum Depth of Discharge for opportunity charging is between 30% – 70%. A minimum charge time of 1/2 hour and an additional cool down period is recommended for best results.
