Did you knowthat the purity of the lead plates and the conductance surface area in a battery determine the Amp hour capacity and life expectancy? Did you know that a battery's capacity is depleted and no longer holds a proper charge when its internal corrosion exceeds 30%? Did you know that, to save cost, some manufacturers use recycled lead obtained from . . . that's right - discarded, corroded batteries? The problem is, if a 'new battery' contains recycled lead, are you getting the best? At ELK we use only the finest materials, including virgin lead, to make our batteries, because we believe the customer deserves the best. We never scrimp onthe materials, so you always get 'the best'.

ELK Sealed Lead Acid Batteries are excellent for the following applications with regard to size, Amp hour rating, and proper terminal connections: battery backup (for Access Control Systems, Fire Alarm Systems, and Security Alarm Systems), emergency lights, lighted exit signs, and uninterruptible power supplies.

The NEW and improved ELK-BLT v.2 Battery LifeTester is a compact, easy to use Mhos Meter for testing 12 Volt rechargeable batteries. Unlike ordinary testers which only measure static criteria, the LifeTester measures internal conductivity, which is the best indicator of a battery's health and life expectancy. The conductivity value, expressed in Mhos (the inverse of Ohms or resistance), is easily compared to benchmark readings from the included Mhos Chart. The chart then categorizes the battery condition as "Best, Good, Weak, or Bad". Every battery type has a characteristic Mhos value when it is brand new and fully charged. The LifeTester is powered by the battery under test and automatically warns when the battery voltage is too low for testing.



Self-adhesive test data labels are included which can be placed on each new battery to record battery measurements for future tests. Additional test data labels are available.
