Intra Technologies today announced an agreement with J.B. Hunt Transport Services to begin retrofitting the trucking company's Freightliner Argosy tractors with Intra low-voltage disconnects (LVD).

The Intra LVD monitors battery levels, automatically disconnecting non-critical power loads when battery voltage reaches critical levels. The unit can be easily installed in any truck by a qualified technician in less than an hour, Intra said.

Will Watson, Intra Technologies' vp sales and marketing, explains that an LVD is an automatic switch that allows truck drivers to enjoy appliances and comfort items during key-off periods while preserving battery power needed to start the engine.
