Rechargeable Sealed Lead Acid Battery
Rechargeable Sealed Lead Acid Battery

SLA (VRLA) batteries are one of the least expensive sources of battery power available, reliable and robust, they are the chosen battery for most automotive and emergency power applications. tolerant to overcharging, they have low internal impedance and can deliver very high currents.

SLA batteries are environmentally friendly and are the world’s most recycled product.

Long Service Life

  • Thick plate design and efficient gas recombination yield a service life expectancy of up to 10 years in standby mode

Low Internal Resistance

  • Superb high-rate discharge characteristics ensure reliable performance

Maintenance-Free, Non-Spillable

  • Proven VRLA technology guarantees safe operation without maintenance and ‘non-restricted article’ status for transportation

Low Self-Discharge

  • Lead-calcium alloy grids and use of high purity lead account for superior shelf-life characteristics permitting storage for extended periods of time

Designed-In Reliability

  • Cutting-edge manufacturing and process control combined with meticulous quality assurance procedures guarantee consistent and dependable performance

General Specifications

  • Nominal Voltage= 12 volts (6 cells)
  • Approximate Weight= 32 lbs (14.5 kg)
  • Energy Density (10 hr rate)= 1.49 W-h/in3 (91.14 W-h/l)
  • Specific Energy (10 hr rate)= 15.75 W-h/lb (34.72 W-h/kg)
  • Internal Resistance (approx.)= 8.0 milliohms
  • Max Short-Duration Discharge Current (10 sec.)= 263 amperes
  • Case= ABS Plastic (UL94 V-O flame retardant)

Operating Temperature Range

  • Charge= -4°F (-20°C) to 122°F (50°C)
  • Discharge= -40°F (-40°C) to 140°F (60°C)

Nominal Capacity

  • 20 hr (2.25A to 10.80 volts)= 45.0 AH
  • 10 hr (4.2A to 10.80 volts)= 42.0 AH
  • 8 hr (5.2A to 10.50 volts)= 41.6 AH
  • 5 hr (7.20A to 10.50 volts)= 36.0 AH
  • 3 hr (10.90A ot 10.50 volts)= 32.7 AH
  • 1 hr (25.2A to 9.60 volts)= 25.2 AH

Cycle Applications

  • Limit initial current to 12.6A. Charge until battery voltage (under charge) reaches 14.4 to 14.7 volts at 68°F (20°C). Hold at 14.4 to 14.7 volts until current drops to under 420mA. Battery is fully charged under these conditions, and charger should be disconnected or switched to “float” voltage.

Shelf Life (% of nominal capacity at 68°F (20 °C)

  • 1 Month= 97%
  • 3 Months= 91%
  • 6 Months= 83%

“Float” or “Stand-By” Service

  • Hold battery across constant voltage source of 13.5 to 13.8 volts continuously. When held at this voltage, the battery will seek its own current level and maintain itself in a fully charged condition.
