TOPDONCar Battery Tester BT300P-A, 12V 24V Battery Tester with Printer, with Battery Test, Cranking Charging Test for 100-2000CCA Batteries, Carrying Bag, 3 Rolls of Printing Paper Included

The first impression of this tester is really good, it comes well packaged in a nicely designed box, which feels good quality and looks the part too.On opening, I found it’s all in a very nice zip case which is also very good quality, and a very nice touch. It looks good in my roll cab. The case holds the tester well and keep it organised, and as an added bonus, comes with some extra rolls of paper for the printer.To use, it’s pretty self explanatory if I’m honest, it’s easy to navigate the menus and doesn’t take much figuring out. Just clamp it on and go. I love the fact that it’s backlit, I’ve had testers in the past which aren’t and they can be difficult to read in bad light.Things I like:- Packaging and Presentation- The storage case/bag- Feels like a good quality item in your hand- Easy to use, and seems to deliver accurate results when compared with other testers and my multi-meter- Backlit display- Good quality clamps, though they could be better as I’ll explain below.Things I dislike:- Battery clamps could go a step further if they were more needle nose, I find it difficult to squeeze them onto some terminals.- Printer paper tears off a little short and often gets stuck and crumples inside the unit. A trivial con really, but can be irritating. Can be overcome if your careful how you tear it off, but could be better to avoid this if the lid had more of an internal guide.Summary:A nice unit to have and to use, I’ll have it for a long time. I find it to be accurate enough, and it all stores away nicely in its bag when not in use. I’d recommend it if you have need to tear more than the odd battery.When the weather gets better and I’ve used it some more, I’ll endeavour to do a video showing it’s use and features in more depth.

Great little tester. Works really well, and easy to use

Bought after seeing it on a video. Easy to use. Needs 2 people for the charging test, noticed that on the video too. Otherwise, quick and easy and hopefully, correct results.

I needed this to read the battery before going to an MOT due to an electrical issue I tested with this device and then took it to Halfords to have it read on there machine and the reading was exactly the same as on this and saved me money knowing full well it was not the battery that was the causality.Nice and simple to use and very easy screen to read as long as you know how to read car batteries and the different Models/Amps.Good build quality, Good clear easy to read screen and a well built device.

Really accurate & saves time by diagnosing crank amps. Tells you basically if the voltage is good which you think is a good battery, but diagnoses that internals are knackered & cranking amps are shot & battery needs replacing.Good news if the battery crank amps are ok it will tell you so & will tell you you you just need to charge battery. Can check if alternator is charging battery also. Good little unit really clear & simple to use.

Good value battery tester which just didn’t perform as well as expected.Returned this one and bought the Ancel battery tester instead.

I liked everything about this. Multiple functions available in the menu and very easy to use.Quality product.

works really well, well packaged. Comes in a nice box with a really neat carry case for the actual charger. It's pretty easy to use to be honest as well... quite intuitive which is good... seems to work very well... handy as hell being able to print off your results as well .. I like that it tests the vehicles ability to recharge the battery and its cranking power...Defo impressed with the seller and the product. Great contact and very quick to get sent out and delivered to me.Would absolutely use them again for more products and glad I have this tester
