Industrial Batteries

Scissor Lift BatteryAt Worldwide Battery, our definition of an industrial Battery is any battery or battery pack which is designed exclusively for industrial or professional uses; used as a source of power for propulsion in an electric vehicle; unsealed but is not an automotive battery; or sealed but is not a portable battery.

Industrial batteries are the batteries of electric vehicles used specifically for lifting and moving materials in locations such as warehouses. Worldwide Battery knows how important electric vehicles such as forklifts and lift trucks are to your business. We sell new forklift batteries, chargers, new lift truck batteries, and new industrial batteries for electric fork lift trucks, lift trucks and electric trucks.

Below are some basic facts and information about Industrial Batteries.

Industrial deep cycle batteries

Sometimes called “fork lift”, “traction” or “stationary” batteries, are used where power is needed over a longer period of time, and are designed to be “deep cycled”, or discharged down as low as 20% of full charge (80% DOD, or Depth of Discharge). These are often called traction batteries because of their widespread use in forklifts, golf carts, and floor sweepers (from which we get the “GC” and “FS” series of battery sizes). Deep cycle batteries have much thicker plates than automotive batteries.

Plate ThicknessPallet Jack

Plate thickness (of the Positive plate) matters because of a factor called “positive grid corrosion”. This ranks among the top 3 reasons for battery failure. The positive (+) plate is what gets eaten away gradually over time, so eventually there is nothing left – it all falls to the bottom as sediment. Thicker plates are directly related to longer life, so other things being equal, the battery with the thickest plates will last the longest. The negative plate in batteries expands somewhat during discharge, which is why nearly all batteries have separators, such as glass mat or paper, that can be compressed.

Automotive batteries typically have plates about .040″ (4/100″) thick, while forklift batteries may have plates more than 1/4″ (.265″ for example in larger Rolls-Surrette) thick –  almost 7 times as thick as auto batteries. The typical golf cart will have plates that are around .07 to .11″ thick. The Concorde AGM’s are .115″, The Rolls-Surrette L-16 type (CH460) is .150″, and the US Battery and Trojan L-16 types are .090″. The Crown L-16HC size has .22″ thick plates. While plate thickness is not the only factor in how many deep cycles a battery can take before it dies, it is the most important one.

Most industrial (fork Forkliftlift) deep-cycle batteries use Lead-Antimony plates rather than the Lead-Calcium used in AGM or gelled deep-cycle batteries and in automotive starting batteries. The Antimony increases plate life and strength, but increases gassing and water loss.  This is why most industrial batteries have to be checked often for water level if you do not have Hydrocaps. The self discharge of batteries with Lead-Antimony plates can be high – as much as 1% per day on an older battery. A new AGM typically self-discharges at about 1-2% per month, while an old one may be as much as 2% per week.
