TOPDON AL500B OBD2 Code Reader, OBD2 Scanner with Full OBD2 Functions and Battery Tester with 12V Battery Tests, 12V 24V Cranking and Charging Tests, Free Software Update

Highly recommend this code reader and battery tester.It arrived in a neat case with all the cables needed and "idiot-proof" instructions. It is small enough to be able to keep in the glove box of the car at all times.The first time out, I used it to investigate an ABS light. It told me which side the faulty sensor was on and reset the fault without any fuss.Good sturdy build without a hefty price tag.Would be handy to check faults before taking to a mechanic to give an idea of problem or for taking along to view potential car purchases.

I have purchased several products now from TOPDON as their products I find are of great quality and reliability and this is another that ticks the boxes. The great feature of this reader is its able to multi task.1. Code reader easy to use and navigate only had 2 weeks so haven't used in anger yet. I have 1 car with a fault Seat Leon which unfortunately could not connect but may just need a software update will contact TOPDON for advice as I have another cheaper reader from the same company and this reads no issue.My other car Subaru connected no issues but no faults to fix or read unfortunately.Then you simply unplug amd plug in the battery clips.2. Battery testing capability this is great works a treat with several easy to use options from specialist batteries to your standard lead acid batteries.I will update this review once I hear back from TOPDON or get round to updating.

Really well manufactured piece of equipment, it comes complete with its own excellent case, from the moment I took it out of the box I knew this was a well made quality item. I found it very easy to use, self explanatory once hooked up to the car, it even features a light within the plug so you can see where the car socket is and makes connecting up easier on some cars. The battery tester works well too, all in all a very handy piece of equipment, essential nowadays with all modern cares with engine and all other systems that require codes to be read. I thoroughly recommend this OBD2 Scanner and Battery Tester

Works well as a batterybyester and most of your code reading but not quite great as a code reader. Good enough to check what your engine is error on but it really excellent as a battery tester.

I was a little sceptical about this product but it actually does a good job. I bought it to see codes and be able to clear them. Simple to use and works as described.

Really good fast delivery service. The TopDon AL500B OBD scanner & battery tester was bought after reading several reviews as how good the product was, after watching a you tube video explaining how to use it and the different test that can done. For the price that seemed good for that particular model which also includes the method of testing a car battery. The scanner has got all the relevant cables and a manual on plugging in and setting up to test etc in your car. It also has a nice well made pouch to keep it in, haven't used it yet as getting to grips as still reading the manual but will give another update later. By the way a manual can be downloaded from the net and saved and printed on a PC.

There are a few issues with this product in my view.1) There is no adjustment for the screen brightness and it is difficult to read it outside, in daylight (and this is important because most of the time, you will probably want to test your battery outside, whilst it is fitted in your car).2) The lack of an internal battery means that as soon as you disconnect from your car battery, it dies. It would be better to be able to keep the current data 'live' for as long as you need it and that would require an internal power source.3) The Topdon website is not the easiest to find things on and to locate the PC software (to perform a software upgrade) was a faff.4) Once I had found the PC software and installed it, it would not 'see' my product. I contacted Topdon for help and I received a quick reply; but the issue is unresolved - so I cannot update it.5) It doesn't appear to be designed to test new car batteries and seems to provide erratic and unexpected readings. When I spoke to Bosch (who made my car battery), they sent me a data sheet that explains that battery testers of this kind do not produce the necessary load current to meet the requisite EN standard, or take into account other factors such as temperature compensation or battery cycling, for example.6) Have recently had a series of errors show-up on my dashboard (CTBA, ASB, low tyre pressure warnings and others) but the TOPDON does not see any of them. This product does not seem to work for any of the tasks I need it for. Such a shame, I really hoped it would be helpful.

Found it useful for 2 of my cars but was disappointed that it failed to work on my TD5. I paid the extra to get a reader that would wipe ABS codes as they are the plague of Land Rovers and checked before that it eould be compatible.
