May 2025 Current-ly testing the BT100W Battery tester - not shocked its good!
Positive results! (Pun intended)
Over the last few months I've been trying out the TOPDON BT100W Battery tester. Spoiler alert - it's great, but it can give 'iffy' results if you don't connect it correctly so one to be careful of!
So here it is, the BT100W:
Now what I like most about this is the fact it connects to your phone or device via bluetooth which is great for 2 main reasons:
Number 1 you can connect it to the battery and operate the tester from inside the car so you can start the engine and test cranking voltage, turn on consumers and test charging voltage under load etc which just makes life so much easier.
and Number 2 you can screenshot the results and then have a digital record of the test which you can send on to a customer or attach to a report etc and no wasted ink or printer paper so brilliant for the environment!
.
and here are some examples of the screenshots you can save from the tests I've done...
firstly battery test result followed by cranking test then charging test
I've switched from using my VW main dealer battery tester which printed out test results to this one and it's a part of the reason I recently won the 2025 Environmental award at the Car an Aftermarket Trader awards so thanks TOPDON!!
and even managed to make it into the newspaper too!
Here's the beginning and end screenshots of the digital version of the article:
