PRX Rechargeable Battery

The PRX can be easily charged in the field - plug it into a 12VDC truck outlet for 15 minutes to get over a days worth of use.  And best of all there's no need to carry around spare batteries!

  • Charge from either 12VDC truck power or a 120VAC outlet
  • A quick 15 minute charge provides one full day of use
  • Battery life on a full charge is one week of continuous use
  • A full charge takes only three hours
  • No battery "memory effect" from frequent charging or discharging


The PRX rechargeable battery uses advanced state-of-the-art battery technology and has innovative features that sets the PRX apart from other proximity voltage detectors.  The rechargeable battery sealed inside the PRX-500 Proximity Voltage Detector is a lithium-ion style battery - the same advanced battery used in smart phones and other portable electronics.  It is substantially larger in charge capacity resulting in much longer operating life for the PRX and lithium-ion batteries out perform alkaline batteries in extreme temperature conditions.
