Sealed Maintenance Free with lead calcium expanded grids
Built in hydrometer (most batteries) – Indicates 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 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 arrester – 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 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.
