This Osaka TA-2500 Supreme Battery is 230Ah Deep Cycle Tubular Lead Acid Battery. It can be fitted in all compatible UPS & Solar System.

Osaka is pioneer in manufacturing 12V Tubular Flooded Lead Acid Batteries. These batteries are Deep Cycle and specifically designed for Solar & UPS applications. The production design of this battery is different to the existing SLI (Starting, Lighting & Ignition) and traditional UPS batteries. It has a Tubular Plate for positive and a thick negative plate for high dept of discharge thus enhancing battery life.


Battery Features:

  • Tubular Positive Plate & Thick Negative Plate for increased battery life.
  • Low internal resistance with good electrical performance
  • Float indicators are provided to help determine electrolyte level easily.
  • These batteries have life of over 1500 cycles at 60% Dept of Discharge (DoD). (For details refer to DoD graph in ‘stats for geeks’ section)
  • Easy Carrying Handles
  • Low self-discharge


  • Solar applications where high battery cycle is desired
  • UPS & Inverter System
  • Telecom Power Supply
  • Electric energy storage banks for solar and wind farms
  • Private Automatic Branch Exchange (PABX) and VoIP backup system
  • Commercial & industrial applications

[[ PRO TIP ]]

BatteryMAX highly recommends using Deep Cycle batteries over conventional batteries for Solar & Inverter applications. Deep Cycle batteries provide high Dept of Discharge (DoD) which means you can extract maximum energy from these batteries without significantly effecting its life (compared to non-deep cycle batteries). Also bear in mind that battery life is characterized in terms of ‘cycles’ which is inversely proportional to the DoD.
