Displays the current charge level of a 12 V battery in 5 stages using 3 LEDs. This makes it easy to monitor the battery and helps prevent deep discharge. It also checks whether the battery is in good working order and whether it is accepting the full charging voltage from the charger. (When the battery monitor is connected to the battery during the charging process.) The battery monitor is designed to monitor a battery in a closed, active circuit. Standby current consumption: less than 4.9 mA. Technical Specifications Operating Voltage 10.4-15.5 V DC Current Consumption Average < 4.9 mA Display 3 LEDs for: Full (green), Low (yellow), Empty (red) Measuring range (Tolerance: max. 5%) - Red < 10.4 V - Yellow/Red 10.5 - 10.8 V - Yellow 10.9 - 12.2 V - Yellow/Green 12.3-12.6 V - Green > 12.7 V Dimensions approx. 40 x 40 x 13 mm (without mounting tabs) https://elecena.pl/product/18323533/m188-battery-guard-12-v 2021-05-04 https://elecena.pl/product/18323533/m188-battery-guard-12-v 2022-10-11 https://elecena.pl/product/18323533/m188-battery-guard-12-v 2022-10-20 https://elecena.pl/product/18323533/m188-battery-guard-12-v 2023-04-29 https://elecena.pl/product/18323533/m188-battery-guard-12-v 2023-10-04 https://elecena.pl/product/18323533/m188-battery-guard-12-v 2025-02-07
