LEAD ACID Batteries LEAD ACID Batteries

Lead Acid Batteries

Basic features
  • Simple & Low cost
  • COTS products
  • ~100 cycles
Performances of High end cells
  • MIL-STD-810
  • >1000 cycles
  • Up to +85°C
  • High discharge rates

Technical features:

  • Simple operation, testing electrolyte level or water adding is not required.
  • The cells are equipped with safety valve, activated in 1-6PSI pressure.
  • The battery pack life duration depends on several factors: Charging system, activating battery pack temperature, discharging system (floating or cycles).
  • When using in floating discharging, the battery pack life duration should be between 3-5 years.
  • When using in cycles discharging, the battery pack life duration is influenced by the number of the deep discharging the battery pack went through.
  • Deep discharging shortens significantly the life duration of the battery pack.
  • When using in charging-discharging cycles, the life duration of the battery pack is nearly 300 cycles. The more we perform deeper discharging cycles, so the number of cycles in the battery pack life duration will grow smaller.

Charging:

  • In order to receive full life duration and maximum capacity from the battery pack, it is recommended to perform charging in stable voltage, and in a current no more than 0.3C. The continuation of charging after the battery pack is full, or continuant overcharging, shorten the life duration of the battery pack.

Discharging:

  • For efficient use of the battery pack, discharging in 0.05C-2C current is recommended. It is forbidden to discharge the batter pack under the defined minimum voltage for cell. Over-discharging cause an acute rise in the amortization of the battery pack.

Temperature effect:

  • The battery pack capacity is influenced directly by the temperature and the current level in the discharging process. Temperature under 15OC – reduce significantly the batter pack capacity. Temperature above 50OC may cause damage and distortion of the battery pack.

Additional charging during the storage:

  • It is recommended to recharge batteries which are stored for long periods. Storage in high-temperature conditions raise the battery’s self-discharge and anesthetize the capacity. Following a chart which displays charge options each period.

Charge method charge time storage temperature

16-24 hours, stable voltage 2.275V per cell

every 6 months under 20oC

5-8 hours, stable voltage 2.34V per cell

every 3 months 20oC-30oC

5-8 hours, stable voltage 2.34V per cell

avoid storage above 30oC
