🔋 12V Lead Acid Battery Capacity Tester LCD Meter - Blue with SMAKN Acid Battery Indicator Review

Three stars only because it is difficult to attach. No number of holes cut will ensure a good fit. I had to use black tape around the edges hoping it would look a little more professional. Instead, he just made the installation crappy.

You can use a voltmeter and memorize the graphs for a FULL 12V battery, or you can press the easy button and get this GEM! I've had this since 2015 and it's been in use the whole time! It looks and works just like the day I got it!

This thing is very bright and easy to read. I have a few minor issues with it, but overall I'm happy with it. A few things to keep in mind: 1-ears can break very easily and the screws they give you are very small. I plan to glue :) 2- there is no OFF button. It's also easy to decide whether to install one in series. That's it. Overall I am very happy with this display.

Stunning display. Please note that it is designed for a 12V battery, e.g. B. a car battery. If you want to use it with a lower voltage battery, the bar on the display won't show accurately, as will the %. There is a button on the back that allows you to see the scale and voltage. The voltage matches your battery exactly (not sure how small the battery is, I use an 11v battery and it works fine)

I used this in my own "backup box" which includes a 35Ah deep cycle AGM battery, a 400W inverter, a 12V cigarette lighter outlet and 4 USB has connections. While it won't show you the voltage, it's handy for quickly viewing the status of your battery. I'm thinking of putting one in my truck as I like to sit with the stereo on. Great for custom builds like mine or something like a golf cart or power chair. Looks good when installed due to the viewing area so only the screen is visible.

Great product at a great price. I really like this product! I use it to control my robot's NiMh battery (as shown below). BTW: 1) When it is on, pressing the button on the bottom changes the mode from % to volts 2) Pressing the button on the bottom When turning on the power, you enter the programming mode / calibration. Some of the things I can do in this mode range) Turn the backlight on/off b) Recalibrate the device to show what the current voltage is, like a new 100% full calibration. I…

Bought because I wanted to use it for my car. Run a 14 gauge positive and negative wire through my firewall to the battery. worked then when i tried to start the car it sounded like a fuse had blown but it wasn't like i had no battery power to the fuse box at all until i could figure out what to do with it. There's a button that changes the readings from percentages to volts, but the button is on the back of the board, so that's a big disadvantage if you're planning on installing this thing…

Seems to work well enough for my needs, but there are a few minor things I want to mention. 1) The color of the front panel is not black (like the photo). It's more of a cardboard color and doesn't feel like a protective sticker that you can easily remove. So it's not as "beautiful" as I was hoping. 2) The front panel is not overlapped except for the left and right screw holes. So if you cut out a space in a back box to mount a gauge, it doesn't look professional. 3) Just note that a voltage…

This is a cute little meter that does the job it was designed for - it shows the percentage of battery remaining and nothing else. If you want to know the voltage, you will need a voltmeter instead of or in addition to this device. I was looking for a digital readout voltmeter and found some nice little gauges. The gauge is clearly designed for installation from the back of the panel. If you try to install from the front, the "bezel" won't be big enough to cover the edges of your cutout. The…
