ELK Products ELK-1233 12V 3.3Ah Backup Battery
Overview
The ELK-1233 is a 12-volt, 3.3Ah sealed backup battery sized for standby power in security and life-safety enclosures where board space is tight. At the 20-hour discharge rate, 3.3Ah covers the standby runtime most local alarm and access control installs specify without oversizing the can — a common problem when a larger-format battery is forced into a panel built around a compact power budget. Weighing approximately 2.75 lbs (1.25 kg), it fits inside standard alarm cabinets and small access control enclosures alongside the control board and transformer without competing for space.
Compatibility
Use the ELK-1233 as a standby power source for 12V control panels and enclosures rated for a 3.3Ah cell footprint, including compact alarm panels, access control boards, and other 12V security equipment sized for this battery class. Confirm the physical cutout and existing battery dimensions in your enclosure before ordering, since panels built around a smaller or larger Ah rating may not accept this footprint.
Installation Notes
Match polarity to the panel's battery leads before connecting — reversed polarity on a sealed lead-acid cell can damage the charging circuit. Because rated capacity is specified at the 20-hour rate, size your standby time calculations off that figure rather than a faster discharge rate, which will read lower in practice. As with any sealed backup battery, keep it within the panel's rated operating temperature range and replace on the interval your system's supervision or local code requires — sealed lead-acid cells lose capacity over time even when not cycled.
