Warranty: 1-Year



The BasicBlinky has a patented circuit that prevents false indication due to leakage paths and tracking on a dirty or wet battery. It has a legendary reputation for reliability and now features an even stronger body.

  • Easy to see and to use: A bright flashing green LED means the electrolyte level is OK; no light means it is time to water the cells.
  • Protects your battery investment: The BasicBlinky helps protect against battery dry-out, a major failure mode for industrial batteries.
  • Installation Forgiveness:  This new feature provides for more tolerance of installation errors, reducing the risk of damaging the monitors during installation.  If the unit is installed incorrectly within the forgiveness zone the LED will not come on but the unit is not permanently damaged and can be corrected.
  • Improves operator safety: There is no longer any need for maintenance staff to peer into vent wells to check levels.
  • Fits almost all batteries: Blinky monitors are available with many standard probe lengths, and can also be easily trimmed to any custom length.
  • Engineered to be even tougher: The new streamlined BasicBlinky body is now even stronger and built to withstand the harsh environment of industrial battery applications. Its materials are resistant to corrosion and its low profile protects it against damage from battery cables and other hazards. It is designed to last for the life of the battery.
  • Inexpensive and cost effective: Over a battery’s lifetime, the BasicBlinky saves a surprising amount of time – or labor cost – and delivers a rapid return on investment. The cost of a single BasicBlinky is a very small addition to the purchase price of an industrial battery; but it allows watering on a labor-saving “as-needed” basis instead of a “hit or miss schedule” basis. This is even more important with batteries that require less frequent water additions.
  • Battery friendly probe: The probe is lead so there is never a fear of poisoning the lead acid battery into which it is placed.
  • UL Classified:  The BasicBlinky battery watering monitor is UL Classified so that you can be assured of its safety.
  • Satisfaction guaranteed: The BasicBlinky is covered by a one-year limited warranty.
