The only exceptions are the buzzer and OLED display. The positions of the components and wiring are similar to my actual board. To understand the schematic easily, I have drawn it on a perforated board also. Please do not attempt this if you are a novice. This tutorial was written for those who have knowledge of rechargeable lithium-ion technology. I cannot be held responsible for any loss of property, damage, or loss of life if it comes to that. Note: Please dispose of the bad batteries properly.ĭisclaimer: Please note that you are working with a Li-Ion battery which is highly explosive and dangerous. I hope this little tester will be useful, so I am sharing it with you all. But for the time being, I am happy with it. In the future, I will try to implement those things. The accuracy of the tester won’t be 100% perfect, but it does give reasonable results that can be used and compared with other batteries, so you can easily identify good cells in an old battery pack.ĭuring my work, I realized, that there are a lot of things that can be improved. This version is a really simple one, which is based on Ohms Law. If you enjoy my work here on Instructables, consider joining my Patreon, it will be a great help for me to make more interesting projects in the future.Ī few weeks ago, I have started the project from the basics. So I really wanted a way to measure each cell's exact capacity instead of their voltages.
#BATTERY TESTER HOW TO#
Earlier in one of my Power Bank Instructable, I told, you how to identify good cells by measuring their voltages, but this method is not at all reliable. It is very difficult to identify the good cells in the battery pack.
This makes it easy to make out the information it provides. The battery tester also comes with a display which is extra-large. They are uniquely designed and will provide you with a positive grip. What made me take note of this battery load tester were its clamps. Speed and accuracy are benefits that put it ahead of the competition. The best thing about it is that it will only take you 10 seconds to achieve.
This is the go-to solution if you want results which are reliable and accurate. This battery load tester is ergonomic and happens to be heavy duty. It is something that should not be neglected, in order for us to experience comfort. OTC 3181 130 Amp Heavy-Duty Battery Load TesterĮrgonomics are important, regardless of the product we are using.
Make sure it is easy for you to understand and use. It is important to know what purposes you intend to use it for, before settling for one.Įase of operation: Ensure that the battery load tester you buy won’t give you a hard time. Purpose: some battery load testers can perform a variety of functions. You may end up not able to use it if you are not keen. The kind of battery: It’s important that you get the right kind of battery tester for the right kind of battery.
