  • Maintenance free design eliminates the need to ever add water to the battery
  • Sealed enclosure allows mounting the battery in any position (except upside-down)
  • To help improve vibration resistance, the battery acid is absorbed between the plates with fine microfiber glass mats (AGM)
  • Internal gas pressure is valve regulated to prevent any water loss (VRLA)
  • AGM & VRLA combined with lead-calcium grid plates provide more cold cranking amps than lead acid type batteries with up to three times the life span
  • Includes a sulfation retardant that dramatically reduces the battery killing plate sulfation that is commonly associated with conventional batteries
  • Extremely slow rate of self-discharge when not in use, but must be slow charged at least every three months if not in service
  • Includes cable mounting hardware
  • * Includes mounting kit with terminal cover and plastic bumpers

Important Note: These batteries include a separate battery acid pack and must be used to fill the battery before use (except 10023 and 10049, these come pre-filled and charged). The metered acid pack delivers the precise amount in a safe and controlled manner. Filling and charging instructions are included.

Note: Battery warranty is based on a six month pro-rated policy. SIX MONTH BATTERY WARRANTY STARTS WHENEVER THE DEALER FILLS THE BATTERY WITH ACID AND SLOW CHARGES IT TO A RANGE OF 12.8 THROUGH 13.2 VOLTS. Please call your salesperson for details.
