Water when needed, not when guessed

Right Time, Right Water Level, Longer Battery Life

A significant problem with battery maintenance is determining when to top off batteries with water. Without indication, operators often need to devise watering schedules or conduct periodic inspections to maintain the batteries. 

The Blinky watering monitors dramatically improve battery maintenance by intelligently alerting personnel when a battery needs water,  and when it does not. These monitors enable watering on a labour-saving, “as-needed” basis, rather than a hit-or-miss schedule. Watering too frequently can cause electrolyte boilovers, which reduce battery capacity by three percent for each occurrence. A lack of water in batteries results in a low electrolyte level, which can eventually cause permanent damage to the cells. 

The Blinky watering monitors help ensure your battery fleet's electrolyte levels are always within the optimal range.

Why Battery Watering Monitor Matters

Extend Battery Life

Under-watering causes permanent cell damage, while over-watering leads to costly electrolyte boilovers. A watering monitor ensures precise maintenance, protecting your investment and maximising battery lifespan.

Enhance Productivity

Manual checks and rigid schedules waste time and resources. With clear, visible alerts, watering happens only when needed, streamlining workflow, cutting downtime, and freeing operators for higher-value tasks.

Maximise ROI

By extending battery life, reducing errors, and lowering maintenance costs, watering monitors deliver measurable savings. The result is a faster return on investment and consistently reliable battery performance.
