ELK BLT Battery LifeTester

Keep surveillance, alarm and backup power systems reliable with the ELK Products ELK BLT Battery LifeTester. This compact battery testing device performs non-destructive conductance (Mhos) testing on 12V rechargeable batteries — the most accurate indicator of battery health and remaining life. Technicians benefit from immediate, actionable readings on the numeric LED display that shows both battery voltage and Mhos values, helping you validate capacity without discharging the battery.

Built for field service and preventive maintenance, the BLT is lightweight (approx. 2 lb) and includes replaceable test leads, a padded carrying case and self-adhesive data labels for easy baseline tracking. Use the BLT to establish initial Mhos baselines and compare readings during routine inspections of physical security, CCTV surveillance, UPS and monitoring systems to reduce unexpected downtime. RoHS-compliant and made in the U.S., the ELK BLT offers reliability and long-term support with a lifetime limited warranty.

Add the ELK BLT Battery LifeTester to your toolkit to streamline battery monitoring, prolong backup battery life and protect critical security and IT infrastructure. Order now for smarter service calls and preventive maintenance.
