12V Battery Meter Lead-Acid Battery Indicator Fuel Gauge Ba-ttery Monitor and Tester for Motorcycle Golf Carts Car Marine ATV with 5 Segments LED Indicator

It works excellent

I actually really like this. It’s inexpensive and works great. Easy to mount to a battery box and gives an accurate state of charge. (I have a cheap lead acid battery bank of 2 batteries that are 12v). Recommend if you’re only looking for state of charge on the cheap.

Very small unit but seems to work well. Wire is very small and difficult to attach a clip for the battery connection.

Shows my battery life on my boat battery. Does as it should.

Much too small for practical use on a dashboard or some such. I was deceived by the pictures. This is way too small.

I use my meter for my marine battery. I Used trolling motor all day and meter still showed 100%, when I put on charger it showed 50%. Inaccurate reading which could be a difference on getting off the lake Ben needed.

I camp a lot without electricity and depend on my rechargeable Marine battery. Since I don't have a battery gauge inside the RV its been great being able to check my levels with this simple tester which stays attached to my RVs batter and rest on top of the battery cover.

This meter works great! It takes the guess work out of how much charge is left in my battery. I use it with a trolling motor and was surprised to see how much charge I still had in the battery after two hours use. I have always been cautious when out in the boat after trolling for a couple of hours. I thought I’d better call it day fearing I was getting low on the battery and not wanting to have to paddle back in. Now with this meter I hook it on the battery and check it periodically. It’s given me more fish time! Definitely recommend it.

very good
