Replacement Battery for 12 V Systems

The Sigma Power Systems 12 V 9 Ah unit is a sealed lead-acid battery built to match original OEM specifications. It arrives new with a T2 terminal and dimensions of 5.94 X 2.56 X 3.74 inches. Buyers should confirm voltage, capacity and physical size against the existing battery before ordering.

Suits Direct Swaps; Not for Different Specs

This battery fits owners who need a like-for-like replacement and plan to reuse their current cables and connectors. It will not suit installations that require a different voltage, a higher amp-hour rating, an alternative terminal style or a different case footprint.

Steady Output Over Long Discharge

Sealed lead-acid chemistry delivers consistent voltage across extended discharge cycles rather than short bursts. The 9 Ah capacity supports prolonged backup or standby use, and the rugged construction is designed to meet or exceed OEM endurance requirements under continuous load.

Questions about this item

What existing cables and connectors must I reuse with this 12 V 9 Ah T2 terminal battery?

You must reuse your current cables and connectors; the shipment contains only the replacement battery with T2 terminals.

Will this 5.94 x 3.74 x 2.56 inch battery fit the same compartment as my old unit?

Compare the 5.94 inch length, 3.74 inch height and 2.56 inch width to your existing battery to confirm it fits the same space.

How can I confirm the 12 V 9 Ah replacement is working after installation?

Measure the terminal voltage with a multimeter; a fully charged unit should read approximately 12 V under no load.
