The all-new, patent pending START PAC® Model Li2800 QC Twin Pac utilizes the latest technology in Lithium batteries and lithium ground support equipment.  Providing the same power as the lead-acid type, these batteries are superior being 42 percent lighter and 32 percent smaller.  Additionally, lithium batteries have two other major advantages:

  1. Twice the battery life of lead-acid batteries
  2. No sulfation problems (can be left in a discharged state without causing damage)
