If you’re anything like me, you know what it’s like for your car battery to fail. Sometimes this is just a minor inconvenience; sometimes it can be a major safety risk. I actually got stuck in the middle of nowhere a couple months ago due a dead car battery.  I’ve learned my lesson!  That’s why I feel it is so important to be proactive with maintaining your car’s battery. This can be daunting, though, especially if you’re new to the DIY car maintenance world. Fortunately, Kaiweets has a great solution to this problem, so I figured I’d share my review of the car battery tester I’m currently using: the Kaiweets KVB01.

Our Review of the Kaiweets KVB01 Battery Tester

The first thing that caught my attention is the compact size of the Kaiweets KVB01. It’s small enough to fit into your glove box or armrest, making it easy to hold on to. The free fabric carrying case adds an extra layer of protection, ensuring your tester stays in top-notch condition. Also in the box are some easy-to-follow instructions, but you won’t need them after the first use; this tester is easy to use!

This battery tester’s digital screen makes it really easy to understand the condition of your battery. I ran the cold cranking amps (CCA) test, and it showed a bunch of useful info, including how charged it was (54%), the health of the battery (63%), the volts, the cold cranking amps, and the resistance. This info was really easy to follow along with, thanks in part to the clear display. I also ran a load test, and the screen helpfully walked me through how to rev the engine to run the test properly.

Speaking of the load test, I was worried that I might need to call up a friend to read the tester while I revved the engine. I was pleasantly surprised by how generous the cord length was! I could easily use the tester even while I sat in the driver’s seat. This is a huge time saver, and it makes it way easier to test your car battery.

Is it accurate?

Great question. We’re happy to report a resounding yes! The 2014 Kia Soul, the car I used with this tester, has had battery problems for years. Sure enough, it looks like my battery is at 63% health, which is normal but getting a little low. Probably time to start shopping for a new one soon.


Here are some pictures from my test:

Overall, I really enjoyed reviewing this battery tester. If you are in the market for a car battery tester, I can confidently recommend this unit.  If your car has had battery issues in the past or if it sits long periods of time without being used (especially in colder climates), it is a good idea to keep a battery tester on hand.

Where to Buy the Kaiweets KVB01 Battery Tester

Like most things nowadays, you can find this on Amazon, BUT we actually found a sweet 15% Off  coupon code and found that it was much cheaper to buy it directly from the manufacturer.  You can CLICK HERE to view the product on their site and use this discount code for 15% off!: SCA15 

I don’t know about you, but I’m looking forward to staying proactive with my car’s battery and avoiding getting stuck on the side of the road again!  I hope you found my review to be helpful.

Until next time,
