SmartBlinky Tray Monitor

The SmartBlinky Tray Monitor is cost-effective as it can detect and alert you when there is electrolyte in the battery tray, so it can be removed before the damage is done, instead of purchasing a tray replacement.

It's easy to use as it has bright red and green LED lights and features low power consumption, over-voltage protection, and it fits all lead-acid, flooded cells.
