Save time and avoid costly permanent damage to your batteries with SmartBlinky Pro. Our leading electrolyte level indicator is simple to install and easy to use, providing a clear visual and audible alert so that you know when to fill your batteries, avoiding costly battery dryout.
An audible alarm alerts management when a battery has not been maintained, and for how many days, further enhancing the SmartBlinky’s ability to prevent costly damage to batteries.


SmartDELAY - The SmartDELAY optimises battery filling whilst preventing boil-over. The electrolyte level in a battery can rise and fall several times a day, with SmartDELAY the SmartBlinky’s LED only turns red once the electrolyte level has been low for over 24 hours, reducing the risk of incorrect topping and reducing the topping frequency.

SmartBEEP - The SmartBlinky Pro has a unique beeper that will help you identify a battery that needs water even if you can’t see it. The frequency of the beep indicates for how many days the electrolyte has been low. If the battery is concealed you will still know it needs water and management will be alerted if maintenance is not being carried out.
