Sealed Maintenance Free Batteries

KarPro Tyre & Auto use and recommend all AC Delco SMF Batteries that feature lead calcium expanded grids (Lead Calcium Technology) for improved resistance to corrosion, overcharging, gassing, water usage, self discharge and thermal runaway, all of which limit battery life in conventional lead acid batteries.

The range includes batteries to suit cranking / starting (traditional automotive), high cycle, dual purpose starting / deep cycle and deep cycle applications.

Feature & Benefits

  • Built-in hydrometer (most batteries)
    Indicates the state of charge.
  • Factory-sealed
    Makes these batteries maintenance free.
  • Polypropylene case
    Reinforced design is precisely tailored to support the battery elements to withstand road shock and vibration. This strong durable material combines lightweight with high impact strength.
  • Liquid-gas separator area
    Returns liquid to reservoir for longer life.
  • Integrated or rope handle
    For ease of transport and installation.
  • Flame arrester
    Safety system, prevents explosion from sparks outside the battery minimises acid leakage prevents the inflow of dust.
  • Heat sealed covers
    Helps prevent electrolyte contamination and increase case strength.
  • Centered cast on plate strap
    Stronger than thinner gas-burned conventional connectors.
  • Low resistance envelope separators
    Encapsulated negative plates help to prevent shorting / treeing between negative and positive plates as well as aid vibration durability.
  • Increased battery shelf life
    Compared to conventional batteries, up to 12 months shelf life without charging due to the use of calcium / calcium grids.
