BatteryJack inc. 12V 1.3AH AGM UPS Replacement Battery .187 Terminal

SKU CH-0D7W-4ETPV

A 12 V 1.3 Ah AGM battery with .187 terminals designed as a 100 % OEM replacement for UPS units

  • AGM technology prevents electrolyte leakage for safe operation in any position
  • 3 Ah capacity delivers reliable backup power for UPS systems
  • 100% OEM replacement ensures direct compatibility with Werker WKA12-1.3F
  • 12 V nominal voltage matches standard UPS battery requirements
  • 90% gas recombination enables maintenance-free service for 4-7 years

12V 1.3AH AGM UPS Battery

This 12-volt 1.3 ampere-hour AGM battery serves as a direct replacement for compatible uninterruptible power supply units. It uses advanced absorptive glass mat technology for sealed, maintenance-free operation in any position. The unit features .187-inch terminals for secure connection. It is built for buyers who need a drop-in spare to restore backup runtime.

Practical Limits of AGM Chemistry

The sealed AGM design recombines over 90 percent of gas generated during normal use, preventing electrolyte loss and enabling maintenance-free service. Expected floating life spans four to seven years depending on temperature and discharge depth. The non-spillable construction meets international air transport requirements for safe shipping. Buyers who need higher capacity or longer runtime than 1.3AH provides should look elsewhere.

Upgrading From Worn-Out UPS Cells

This battery replaces the original Werker WKA12-1.3F cell when runtime has degraded or the unit fails self-test. A three-year warranty covers UPS and backup device applications, while other uses carry a two-year term. The jump is worth it when the existing pack no longer holds sufficient charge to bridge outages. It is not for users who need a different voltage, terminal size or chemistry.

Questions about this item

Which capacity should I choose for my UPS?

This model is a 12V 1.3AH AGM battery; select it when your UPS specifies a 1.3 ampere-hour 12 volt replacement.

What does the 1.3AH rating mean once installed?

It can deliver 1.3 amps for one hour or a proportional load for a shorter time, giving the runtime your UPS was designed for.

What does the .187 terminal interface cap in practice?

The .187 inch faston terminal limits the connection to a push-on blade fitting; it cannot accept bolt-on lugs or larger spade connectors.
