ACDelco Sealed Maintenance-Free Batteries

All ACDelco SMF batteries 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.

  • Built in Hydrometer ( Most Batteries) – Indicates state of charge.
  • Factory-sealed – Makes these batteries truly 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 light weight 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 Arrestor – Safety system, prevents explosion from sparks outside the battery, minimizes acid leakage,
  • prevents 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 in vibration durability.
  • Increased battery shelf life – Up to 12 months shelf life without charging due to the use of Calcium/Calcium grids.
  • (Compared to conventional batteries.)
