Features

  • [12V Battery Tester] The BT300P is a quick and accurate battery tester that offers printed diagnostic receipts. Know everything about the health of 12V batteries, the 12V & 24V starter motors cranking status, and 12V & 24V vehicle electronic systems charging condition. This is TOPDONs newly developed battery tester that ensures your batteries are always working at an optimum level.
  • [Wider Application] This device works on a wide variety of 12V automotive lead-acid batteries, such as 100~2000CCA regular flooded, AGM flat plate, AGM spiral, Gel, and EFB. It detects the failure of the starting and charging systems in 12V & 24V cars, motorcycles, trucks, RVs, ATVs, SUVs, boats, yachts, and even lawnmowers. Most vehicle issues caused by a defective battery can be fixed with the BT 300P.
  • [Fast & Accurate Test Results] Featuring TOPDONs latest conductive battery testing technology, this modern battery tester can identify the exact reason why your battery failed in only 3 seconds. Research shows that its results provide an accuracy of 99.5% - more precise than competing battery testing equipment.
  • [User-Oriented Battery Load Tester] Its 2.4 color screen shows crystal-clear readings at any lighting condition. Intuitively placed buttons allow you to toggle menus with ease. With the built-in thermal printer, you wont have to worry about running out of ink. No ribbons, cartridges, or other supplies are needed for its use. Standard thermal paper is the only refillable supply required to print your test results.
  • [Extra-Safe Operation] With spark-free copper clamps, PVC-coated wiring, and built-in automatic protection against reverse polarity, the BT300P provides the extra safety you need when battery testing. Its insulated ABS shell prevents current leaks and can withstand damage. With an extra-long 31.5 cable, this car battery tester is even more convenient to use.

    • Easy to use.
I liked how easy it is to use and how it prompts you on what to test next. Seems accurate to me. Also like that you can print a report out. The printer did not jam and worked great.

    • Good for its intended use
Bought them for my shop so we can test every car. Right of the bat had a few battery tester come apart which felt a bit disappointment but did get a chunk of them. The others kept working for a good year until they eventually gave out as well. Good for not a high volume shop since its not to durable. Aside from that its easy to use and print ... show more

    • Great product and price
I purchased this product due to the winter stress on batteries in my vehicle and work vehicle. I wanted something dependable and easy to use and yet affordable. I was amazed at the simplicity and yet professional grade of this item. I am very highly satisfied with it and I brought my printout and the tester to the local auto store to prove my battery was defective and needed warranty replace. They had one obviously but it was quickly handled and replaced with no hassle thanks to this product. I was also able to rightfully test my other batteries in my other vehicles and plan to have them replaced as well due to the status of knowing before I even drive out of my way to the store. So awesome and professional and the price is very reasonable and I highly recommend this product. The replacement printer paper is also very affordable and should last you a long time. It comes with 3 rolls one of which is installed already in the unit. I purchased an extra 12 roll set at a combined reduced price from Amazon. It delivered on time and I love it. Thank you Topdon and Amazon. ... show more

    • Topdon is a go to but...
So i recently starting purchasing topdon tools . i got the new diag900 lite scanner and i love what it can do for the price. Its limited with features but does the job when needed. Next i purchased the battery tester that i could use with scanner ( Btmobile pro) and i was happy to start using this with the scanner but it doesnt work with that scanner for some reason so they wanted me to go to the BTmobile pro S . I didnt want to spend ($150) . So i returned the BT mobile pro and next i purchased this BT300p . When i received it i was loving design but then first time used the paper jammed on me 3 times and i didnt like that. So i went on amazon to search though the reviews and confirmed that few other people were having the same issues. So i returned this one also. So right now topdon isnt my go to for battery testers. Right now going to a different brand. Updated info: top don has been in contact with me about this battery tester and they will be checking into it. I really like that companies care what customer think about there products. So I will be working with top don to fix this issue with battery tester ... show more

    • Excellent Tool
Pretty cool battery tester. It's fast, easy to use, a single press of a printer after reports. It's great and all but the printer can be a issue because it gets stuck underneath and it won't print all the way. It's best to pull the paper out a bit for a opening so it can print out easy. So yeah, best tool ever! ... show more
