Product identity

The BatteryJack inc. BPL3.3-12 is a 12V 3.3AH sealed lead-acid battery built with AGM technology. It serves as a direct 100% OEM replacement for UPS units, emergency lighting, fire alarm panels and security systems that require a compact standby power source.

Thermals noise power

AGM construction makes the battery maintenance free and eliminates liquid electrolyte spill risk during normal float service. The sealed design produces no audible noise and generates negligible heat while held at standby voltage in UPS or telecom cabinets.

Sustained load behaviour

During extended discharge the battery delivers stable voltage for backup power in alarm, communication and auto-control equipment. Expected service life spans 4 to 7 years in float applications, and the supplier provides a 3 year warranty on UPS and backup devices or 2 years on other equipment.

Questions about this item

How do I install the BPL3.3-12 and what is the common mistake with the terminals?

Place the battery so the terminals sit 1.6 inches apart and connect the positive lead to the positive post first; reversing the polarity is the step most often done wrong.

What maintenance or replacement will this 12V 3.3AH AGM unit need later?

It is maintenance-free, so no water topping is required; plan to replace it after the 4-7 year expected life when runtime drops below the needs of your UPS or alarm panel.

What limit appears first under sustained use?

The 3.3AH capacity sets the runtime ceiling; once the stored charge is depleted the voltage falls and the connected UPS or security system will shut down.
