The Elak Automotive Battery Chargers are designed for precise charging of VRLA (valve regulated lead acid), sealed maintenance free, lead acid and other batteries. These batteries require a sophisticated charger to charge them in a precisely regulated fashion specified by the manufacturer to avoid irreversible damage through gassing and shortened service life.

The Elak Automatic charger meets the charging specifications of a wide range of VRLA and RG sealed batteries very accurately. The charger delivers a measured constant current to the battery until the manufacturer’s specified maximum battery voltage is attained. This voltage is then held constant for a specified period to allow a uniform charge across all the plates. At this point, the current is allowed to taper down to a value sufficient to trigger the float voltage. The charger may be left connected indefinitely to a fully charged battery without the fear of over-charging or damage.
