I have been wanting to try a battery tester for a while now, with four cars at home - three of which are used infrequently and on/off trickle chargers, I decided to give the BT200 a try and see how the various batteries were doing, what kind of condition they were in, and how the results compared before and after trickle charging. First up was our "daily" fitted with a Stop-Start EFB battery. This is a few years old so was interested to see what sort of health it was in. I hooked up the BT200 and it sprang to life. CCA (Cold Cranking Amps) is the test of choice so I chose to do the battery test, CCA, set the amps value (which can be found on the battery itself) and away the test went, coming back at 95% healthy and 100% charged. Not bad. Interesting as the Stop-Start function no longer works in the car and I always assumed it was because the battery was getting old...not so it would seem! A new EFB battery is around £150 so I won't be forking out for one any more knowing the battery is still in fine fettle! Onto the next car. The battery is tucked deep into the side of the boot space and very difficult to access the terminals with limited space. The croc clips on the BT200 are pretty chunky so the problem was exacerbated somewhat. I struggled to get a good connection onto the battery, and as a result the first report came back with very strange voltage readings and a 4% rating for the battery health. After fiddling with the connections a bit more I got the correct reading - 36% healthy with 0% charge - which seemed about right as the car hasn't been used for a few days and hasn't been hooked up to the trickle charger. At this point I hooked up the car to my CTEK trickle charger to test the result the next day, which I did - and the result came back with a 100% charged, 100% healthy battery! Excellent and interesting to see the change after charging. The last car to try has a relatively new battery (3-4 months old, however the car has not been driven at all in this time, and sits on a trickle charger). I was expecting this to give a perfect result - and was surprised to see just 63% health and 0% charged! Confused, I checked the charger only to find it was disconnected at the plug, I have no idea how long for! So I plugged it back in, and ran the test again the following day to find it back to 100%/100% health, excellent and again very interesting to see the change. Again though, the battery on this car is in a deep well with limited space and as before I struggled to get the chunky clips in place, having to do several tests and re-attachments before I got the correct reading. So in summary, a very neat, compact device that works well when properly attached. If you get poor results from a battery that you think is ok, do check the connections and runs additional tests just to make sure you are getting the correct results. I should stress this wasn't an issue on my main car as the battery was easy to get to with plenty of room around the clips to attach them properly. The manual does also specify that the connection should be good and the terminals clean to ensure you get accurate results. I guess I was just a little surprised at how sensitive the device was. My only disappointment is that the manual - although it looks pretty big - is only small (with multiple languages) and doesn't really go into any details of the other tests - what they are for and how they work etc. I will mainly use this for the more common CCA test, but it would be interesting to find out what the other tests are for and how I can use them. Other than that a great piece of kit, well made, nice clear backlit LCD display, and simple responsive menus. Highly recommended if you are after simple-to-use tester that doesn't cost a fortune.

This is a great product. I’ve used it on all my cars very easy to use and the information it provides is very easy to understand. Read more

excellent performance and quality... Read more

Nu testat på flertalet bilar och den stämmer till 95%, är mycket imponerad. Dessutom slipper man krångla med interna batterier då enheten tar sin ström direkt ifrån källan man kopplat in. Önskar jag hade köpt en tidigare då det varit till mycket nytta. Read more
