Replacement battery for Alexander MB5089

This 12V 2.3Ah sealed lead-acid cell is a direct replacement for the Alexander MB5089. It uses AGM valve-regulated technology so it can be mounted in different positions without spilling. The calcium alloy grid reduces electrolyte loss for longer service life. It arrives factory fresh in a rugged ABS case.

Practical limits of sealed lead-acid chemistry

The 2300 mAh capacity suits low-drain standby or cyclic use but cannot sustain high continuous loads. Self-discharge means periodic recharging is required during storage. The battery must be charged with a voltage-limited source matched to 12V SLA parameters. Deep discharge below recommended voltage will shorten cycle life.

The capacity that decides fit

The 2.3Ah rating at 12V determines whether this cell meets the runtime requirement of the Alexander MB5089. Verify the original pack specifies the same voltage and ampere-hour value before ordering. Physical dimensions of 7.01 x 1.38 x 2.40 inches and 2.01 lbs weight must also match the compartment. Buyers needing higher capacity or a different chemistry should look elsewhere.

Questions about this item

Should I buy the 12V 2.3Ah version or a different capacity for my Alexander MB5089?

The RG1223T1 is built to the exact 12V 2.3Ah specification the Alexander MB5089 requires, so this capacity is the correct match.

What does the 2.3Ah rating mean for actual run time in the device?

At 2.3Ah the battery can deliver 2.3 amps for one hour or a proportional current for longer periods; exact run time depends on the MB5089's power draw.

Does the battery use a standard terminal interface that fits the MB5089 without adapters?

Yes, it is a direct replacement for the Alexander MB5089 with valve-regulated spill-proof construction that allows installation in multiple orientations.
