SEALED MAINTENANCE FREE (SMF) 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.

FEATURES & BENEFITS

Built in hydrometer (most batteries) – Indicates state of charge.
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.
Integrated or rope handle – For ease of transport and installation.
Heat sealed covers – Helps prevent electrolyte contamination and increase case strength.
Low resistance envelope separators – Encapsulated negative plates help to prevent shorting / treeing between negative and positive plates as well as aid
vibration durability.

Factory-sealed – Makes these batteries maintenance free.
Liquid-gas separator area – Returns liquid to reservoir for longer life.
Flame arrester – Safety system, prevents explosion from sparks outside the battery, minimises acid leakage, prevents inflow of dust.
Centered cast on plate strap – Stronger than thinner gas-burned conventional connectors.
Increased battery shelf life – Compared to conventional batteries, up to 12 months shelf life without charging due to the use of calcium / calcium grids.
