This battery tester comes from TOPDON and has a strange name ArtiBattery101 but i use AB101 for short. It offers three tests for car batteries, battery test, cranking test, and charging test but is limited to 12V lead acid batteries. Compared with the Kingbolen BM550 which I reviewed earlier, see • 123 - Kingbolen BM550 ... , I definitely prefer the AB101 for testing my car batteries, relegating the BM550 for testing all kinds of other batteries.

Highly detailed discussion, thank you

Very good comparison. Appreciate you efforts

EFB is a sort of middle-ground between FLA and AGM and is intended to survive in modern cars that stop and restart their engine at every stop. They have lower internal resistance than FLA and offer more discharge cycles, but do not perform as well as AGM. EFB can be thought of as a budget-class AGM, but you won't think it's a bargain as car batteries have become insanely expensive.

Very interesting. I've owned this Topdon tester for about 2 years now..found it to be reliable.

@etow8034 Год назад

It depends on the firmware version. There has been at least 2-3 firmware versions since the AB101 was released. The first version you had the option to select if the battery was out or inside of the car, then the newer firmware eliminated that step and the algorithms was able to compensate for that difference automatically.

@etow8034 Год назад

The Topdon BT50 is the new replacement for the AB101. Both are very similar.

Could you compare voltage drop during start of the engine between those two testers an bm you have connected in a crest mode?

@TheHWcave Год назад

You can't really do this with the BM550. It only shows the voltage when doing its (load) test. Someone would have to crank and someone else press the button on the BM550. Since the engine will probably starts during the test, the result would be very random and pretty meaningless. The BM550 can only do a load test before or after the engine is running (so you can check if its charging) but not while the engine is starting.

@@TheHWcave 13:16 which voltage topdon shows? My Konnwei kw 650 can show voltage drop and time spent for start, of course i do not have helper near. The idea is to understand how correct figures from those tester in comparison with brymen.

@etow8034 Год назад

You miss the point with these testers. The "algorithm" is written for automotive size batteries and the size and resistance of the plates in them. These capacitance/resistance testers were developed in the early 90's by Motorola and Midtronics to help quickly check automotive batteries on the car assembly lines and telephone companies to check their back-up batteries remotely without perform a destructive and potentially dangerous load test that could damage the battery.

@TheHWcave Год назад

A tester measures the internal battery resistance and voltage. Those are the only real physical properties one can measure short term on a battery (long term you can measure capacity too). The measured properties are then "interpreted" by each tester using proprietary algorithms based on different battery types. As explained in the BM550 video, there are different kinds of internal resistance, depending whether a DC or AC test is used. If using the same method (AC or DC), the resistance and voltage values on the same battery are really the only things that ought to be directly comparable between testers. This is what I was trying to establish.

@etow8034 Год назад

@@TheHWcave Originally these testers were specifically calibrated for one brand of batteries, the resistance of the clamps and the plates were all taken into account and had to be calibrated and certified at the manufacturer like Midtronics in order to get the most accurate reading, but now 30 years later after their patents have expired 3rd party manufacturers like Topdon have written proprietary algorithms so that these testers can be used with relatively accuracy on different brands and sizes of car batteries.

@@etow8034 Thanks. It is interesting to learn about the history of these testers. It is truly amazing how much testing power and accuracy one can nowadays get for very little money. I wondered what those units 30 years ago would have cost and how big they were. Midtronics has a nice website with a timeline going back to their 1994 model which still used an analog meter. But in 1997 it was already digital
