Description: DC 12V Lead ACID Batteries Indicator Battery Capacity LED Tester Digital Voltmeter

Batteries are awesome tools that let us take our electricity with us, so as to powerElectronicsand even electrical appliances without the need for a power grid or alternative electrical supply. However,Batteriesaren’t always easy to work with, and you sometimes need tools to be able to measure the remaining capacity, the voltage output, as well as the voltage input – in order to properly maintain good battery health for longevity.

Features:

• With a shell, easy to use stand-alone or embedded in the panel on the product.
• Display Mode: Battery +Percentage
• Black wire connect negative electrode
• Red wire connect positive
• Dimension: 47x27x22mm

Usage: Connected the display panel positive and negative terminals to the tested battery positive and negative side, then the digital tube will show the battery level

Battery capacity display parameter:

• Battery voltage >11.2V, 1 Grid Light
• Battery voltage >12V, 2 Grids Light
• Battery voltage >12.5V, 3 Grids Light
• Battery voltage >13.3V, 4 Grids Light
• when battery voltage <11.2V ,the 4 grids all off,it means you need to charge the battery right now

• With a shell, easy to use stand-alone or embedded in the panel on the product.
