Deep cycle Bateries

Designed to provide a steady amount of current over a long period of time, achieves this by using thicker plates. Found in boats, golf carts & solar power systems.

Properties of batteries

  • Cold Cranking Amps (CCA) - amps that the battery can produce at 0°C
  • Reserve Capacity (RC) - minutes that the battery can deliver 25A, voltage > 10.5V

For Deep Cycle batteries, RC is 2-3 times greater than car batteries. 0.5-0.75 of the CCA. Car batteries are not designed to be completely discharged. Deep cycle battery should withstand hundreds of discharge/recharge cycles.

Availability in launch countries

  • Brazil (Specially Rural Areas)
  • Uruguay (Specially Rural Areas)
  • Argentina (Specially Rural Areas)
  • Libya
  • Nigeria
  • Ethiopia
  • Pakistan
  • Rwanda

Vendors

In this part Should go the different specifications of deep cycle batteries, and also availability in the different countries.
