What is a Car Battery Tester
A car battery tester is a special measuring tool designed for testing the charge level of car batteries. To put it simply, this device allows you to check whether the power of a battery is enough for proper performance. A good car battery tester will help you avoid possible problems with the ignition system and other connected issues.
If you've got a vehicle, car inverters and car jacks will definitely be useful accessories for you! In addition, to have a possibility to charge a car battery on your own, select and purchase the right car battery charger!
What Features to Compare
Firstly, you should pay attention to the Type of a tester and its Compatibility with the battery installed in your car. Basically, there are several types of testers that work differently while testing the condition of a battery. A load tester, for example, passes electrical current from the battery through a conductive material inside the tester and delivers test results depending on the voltage drop. A conductance tester tests the resistance across the plates inside the battery. The main advantage of conductance testers is that they allow checking even discharged batteries. In view of the fact that batteries for vehicles come with different nominal voltage, you should select a car battery tester which is right for you. For example, a tester designed for testing 6V batteries won't cope with 12V ones. At the same time, testers for 12V batteries are also suitable for 6V accumulators. So, check the type of a car battery your car is equipped with in advance.
It's also important to determine the type of Data Output you want to obtain since this feature is responsible for the device usability. Some car battery testers have a digital display while others feature an analog one. An analog display can contain certain colored sections with scales for different measurements such as voltage and CCA level. To simplify usage, some battery testers come with indicators showing the charge level of a battery and whether it requires recharging.
Finally, don't overlook Special Features of a car battery tester. Without any doubt, safety should be the top priority, so, be sure to read and follow all safety and handling instructions on the car battery tester before use. Advantageous design, a comfortable handle, weight of the tool can significantly contribute to the ease of use. It's also crucial to pay attention to the type of clamps, they should have dielectric properties and ensure easy connection with battery posts.
OTC 130 Amp Heavy-Duty Battery Load Tester
Choice of Professionals
It's not always enough to have a car battery tester that provides a quick test of your car battery condition, its ease of use also matters. The OTC 130 Amp Heavy-Duty Battery Load Tester is definitely an ideal solution here. The device offers maximal comfort—a well-insulated handle with a power on/off switch ensures great convenience during the measurements. 130 amp load capacity guarantees accurate results for both 6V and 12V batteries. The management is simple enough, all you need to do is connect the load tester to the battery and turn a power switch to the ON position. The accurate reading will be shown on a clearly printed scale with two zones, one of them is intended for 6V batteries while another is for 12V ones. It'll take only 10 seconds to carry out the measurements! It's worthwhile to add that the clamps feature copper contacts for good electrical contact with the car battery posts. Once the testing is complete, the clamps can be fixed on the housing using two special side tabs.
Peculiarities of Deep Cycle Batteries
Deep cycle batteries typically have a high discharge rate and deliver power for a very long time. Unlike starter batteries intended to provide short, high-current bursts for cranking the engine, deep cycle batteries can be used as an additional vehicle battery. Such batteries discharge between 45% and 75% of their capacity, depending on a manufacturer and technical characteristics. Although deep cycle batteries can be discharged to 20% of their charge, we'd recommend you to keep the average cycle at about 45% discharge. It's noteworthy that modern deep cycle batteries can be recycled 98% by volume and 99.5% by weight. All lead plates, a plastic case, sulfuric acid, and other metals are 100% recycled, the only part of a battery that can't be recycled is paper separators.

How to Use a Load Tester to Test Your Car Battery
1. If you decide to check the battery power level via a load tester, firstly, make sure that the ignition is switched off. Then, you need to disconnect the battery's cables. (Note that before disconnecting a battery you need to plug a battery keeper into a cigarette lighter socket to hold the computer codes.)
2. Don't test a battery when it is connected to a battery charger.
3. Before connecting the load tester make sure that the battery posts are clean and free of corrosion.
4. All load testers get hot during use so it's necessary to allow them to cool down between tests. Do not forget that you shouldn't hold the load test button down for more than 15 seconds. Otherwise, you risk making the tester inoperable.Comply with safety regulations and operating instructions to ensure a long service life of a tester.

Did You Know?
Even when car batteries aren't used, they lose their charge. Therefore, if you're going to leave a car battery unused, don't expect it to be completely charged after some time. Interesting enough, at low temperatures batteries save their charge better, so it's reasonable to store them in a cold place. The point is that most modern cars are equipped with on-board computers and different equipment which consumes energy. It's worthwhile to add that all settings should be stored before replacing the battery.
