Using a car battery tester doesn’t require you to have a degree in mechanics, but sometimes you might prefer an easier approach. If that’s your case, the INNOVA 3721 might be the best car battery tester for you. It’s much easier to use than a classic tester, right from the comfort of your car. Simply plug it into the vehicle’s cigarette lighter or power receptacle and wait for a few seconds. But battery health doesn’t change like this, it goes down over time, as the battery gets older and weaker. Can you improve automotive battery health?

Turning ON/OFF any electrical accessories in the vehicle during the test will affect the accuracy of the test result. Steps Some battery voltmeters can be very inexpensive, but they tell you only the voltage – that’s not enough information for you to judge battery health. State of Health (SoH) If the battery voltage is low, it can be topped up with a battery charger or by driving, assuming as your alternator is working as normal. DO NOT place the tester near the engine or exhaust pipe to avoid damage by high temperatures, when the car engine is running. Topdon’s battery testers have an advanced formula which uses the currently measured value for CCA, and compares it to the battery’s rated CCA value (its CCA rating when new). This results in the State of Health (SoH) advice, letting you know whether you’re okay to continue with the battery or if you need a new one. What types of batteries do these testers work with?

Keep hair, hands, and clothing as well as tester leads and cords away from moving blades and belts.

A: It works on 12V regular flooded, AGM Flat plate, AGM Spiral, GEL and Deep Cycle batteries, with CCA between 100 to 2000. The reason batteries lose power and die sooner than they should is sulfation (the build up of lead sulfate on the battery plates). A: Yes. It offers peace of mind with extra-safe Reverse Polarity and Sparkproof protection, and easy operations even if you're new to battery testing. Cold Cranking Amps, specified by SAE & BCI, most frequently used value for starting battery at 0°F (-18°C)The battery test will show the currently level of charge of the battery, the voltage. Your battery’s internal resistance. And the state of health of the battery, showing the current CCA value. Why is its functionality the best on the market? By the way, in another article we’ve written in-depth on Topdon’s battery tester range. Where is the best place to get it? It came onto the market in 2020 so longevity is still quite unknown. All signs look good though, Topdon are a solid manufacturer. This warranty does not apply to damages caused by improper use, accident, flood, lightning, or if the product was altered or repaired by anyone other than the Manufacturer Service Center.

Battery voltage goes up and down day by day, according to how well the battery is charged. So a high voltage doesn’t necessarily mean the battery is healthy, it just means it’s well charged at that particular moment. It’s simple to use. You have the option to choose between testing a battery in or out of the car, not something we’ve seen before.Their support is also pretty good, you can get in touch with them if there’s any problems or questions, and you’ll get a response. What information do these battery testers give me about my vehicle?
