Battery charge indicator informs us about the state of the battery with 4 LEDs. Each of them presents a specific range of the current battery voltage. The big advantage is its dimensions: 22x17mm and weight: 1.8g. This meter can save the user a lot of nerves related to immobilization of the car due to a discharged battery, as well as save money by informing when the battery should be recharged, thus extending its life. Short-distance driving means that the battery is not recharged sufficiently while driving, which results in a significant reduction in its service life. In order to keep the battery in the best condition, it should be recharged when the voltage drops below 12V. Technical data Display range: below 12V: 1 red LED 12V - 12.5V: 2 LEDs 12.5 - 12.9V: 3 LEDs above 13V: 4 LEDs dimensions: 22x17mm weight: 1.8g https://elecena.pl/product/22620986/12v-battery-charge-indicator-xd-82b 2023-02-23 https://elecena.pl/product/22620986/12v-battery-charge-indicator-xd-82b 2025-10-29
