Excellent. Very user friendly. Sturdy with heavy duty insulated battery clamps. I was a motor mechanic for 26 years and have used all kinds of testers in my job. This is one of the most user friendly. It is lightweight yet robust. Does all the tests and provides all the information you need for the battery, charging and starting circuits. As with all testers, they are a guide as to what may or may not be wrong. However it takes away guessing as to what is happening. Very useful addition to have alongside a multimeter and a bit of knowledge.

We have two cars and the stop start is not coming on unless we do very long drives. There is often a warning on the dash of both cars that the battery levels are low. Just to be certain we needed to replace the batteries I purchased this Topdon BT200 car battery tester. Delivery was very quick and I received a message giving not only the date of arrival but also the time (before 1 p.m.) pretty good. The packaging was very good and I’ll use the box the keep the tester in as its well made and has lots of foam padding shaped to the tester. First impressions were that this device is well made and good quality with a nice feel to it. The instructions were very clear and so simple that after using it once everything is pretty straight forward without have to read them again.The clamps are strong and wide enough to grip the battery terminals and have plenty of cable to find an earth point on the engine. The colour screen is very clear and the menu system straightforward. I found that sometimes when testing the battery it displayed ‘replace’ but when tested again 47% so I repeated and found that the battery was around 50%which probably means the connections were not secure on the first try. The charging test, cranking, state of charge and state of health all provided enough information to indicated both batteries needed to be replaced soon. As they are both around 5 years old they’ve done well. The tester also told me that the alternators were fine. I’m very pleased with this device and at £43.50 feel it’s good value for money. Highly recommended.

I needed an accurate tool to test the batteries and charging systems on several vehicles and this does the job perfectly. It's not expensive for what it does. It's intuitive and simple to use but a basic understanding of car batteries will help you get the most out of it. You get a small instruction book written in about 50 languages. It's good, but you need a magnifying glass to read it. I downloaded a copy to read on the phone. It feels solid and robust and has good quality clamps and decent cables. The colour screen is large enough and very easy to read, even in direct sunlight. I was thinking of getting the BT100 originally but this is well worth the relatively small extra cost. I'll test my batteries regularly, especially during the winter months. My only slight criticism is the length of the cables. Whilst doing the charging test you need to hold the engine at 2500 rpm for 5 seconds. Longer cables might allow you to to see the screen whilst doing that. It's a great tool to have, especially if you've got a decent smart charger.

Easy to use and works really well.

Did the job I wanted it to do.

I bought to test lots of batteries etc. Very easy to use, you clamp on and type in the specifications of your battery and then test. The unit uses power from the battery to work. It remembers previous setting. It seems to give consistent readings when you move from battery to battery and back again. Feels well made and is chunky with clonky buttons so perfect for a workshop or lobbed into the back of a van.

Excellent little machine. Easy to use. Bought in deal otherwise wouldn't have purchased it for the full asking price before discount.

Très bon testeur de batterie, simple à utiliser et fiable. Les mesures sont précises pour les batteries 12V et 24V et l'appareil donne un diagnostic clair en quelques secondes. Compact et pratique à ranger dans la voiture. Je recommande pour vérifier rapidement l'état de sa batterie.

Not for normal purpose only can use in Workshop

Un buen analizador de baterías. No necesitas mas. Muy sencillo de utilizar. Conectas los cables a la batería, introduces el tipo y amperaje de la batería y te dice su estado. Así de sencillo. Es preciso en el diagnostico, comprobado por mecánicos y arroja el mismo resultado que los equipos profesionales. Ha sido de mucha utilidad para diagnosticar a tiempo unas baterías antes de que fallen del todo, a mí y y a compañeros, y te deje tirado sin poder arrancar. También me ha servido para averiguar por que mi moto me estaba dando problemas eléctricos, y era por la batería en mal estado, aunque aún arrancaba bien, no arrojaba suficiente potencia para el encendido y centralita y me estaba volviendo loco. La única pega es que no trae un estuche propio para guardarlo. Muy sencillo de utilizar, fiable y practico. Indispensable herramienta para el vehículo.

Very handy tool. Very happy with my purchase

Gut gemachtes Messgerät. Es gehen an jede Polklemme 2 Leitungen ran, jeweils eine dicke für den hohen Laststrom während der Messung, sowie eine dünne Leitung für die laststromfreie Messung der Spannung direkt an den Batteriepolen. Sie sind sogar so weit gegangen, die dicke Leitung an die untere Kluppe der Zange anzuschließen und die dünne an die obere. Nennt sich in der Elektrotechnik Kelvin-Messschaltung, Stichwort "Sense-Leitungen". Nur durch diese Verschaltung ist es tatsächlich möglich, während der starken Strombelastung die die Batteriespannung direkt an den Polen messen zu können. Gut gemacht! Hatte bisher eher auf die billigen, aber auch guten, grobschlächtigen Messgeräte mit Drehspulinstrument und dickem "Tauchsieder" im Metallgehäuse gesetzt. Das Topdon BT200 kann nicht die entsprechenden hohen Ströme aufnehmen, arbeitet aber dennoch nachvollziehbar korrekt, wertet gut aus und das extrem einfach zu bedienen. Was zu beachten ist: 1. nach jedem Abtrennen von der Batterie muss vor dem nächsten Anschließen ein paar Sekunden gewartet werden, damit das Gerät einen sauberen Neustart macht. Schließt man zu schnell wieder an, bleibt der Bildschirm dunkel. 2. tatsächlich an den Batteriepolen messen und nicht an den Fremdstartanschlüssen im Motorraum, da damit der Strommess-Shunt moderner Fahrzeuge und ggfs. zu lange Kabel die Messung verfälschen würden. Gutes Gerät, elektrisch sinnvoll aufgebaut, liegt gut in der Hand. Passt.
