A battery load tester measures the residual current of a battery. This is probably not the most accurate way for sure kinds of batteries. For instance, LiMnO2(Lithium Manganese) batteries, like CR2, have a fairly consistent discharge rate, though not as high as the peak discharge rates seen with NiCad and lithium batteries. (This is because, unlike NiCad, Lithium has higher lithium contents than the other two.) Therefore, the battery's maximum capacity at full discharge is almost the same at full charging as it was at half charge.
This can result in serious short-circuits in your vehicle, short trips to the repair shop, and personal injury. These symptoms are usually only realized if you use your car or truck on a regular basis or are involved in an accident. And, often this only happens to people using expensive brand new heavy duty automotive batteries. But even new cars can suffer from electrical problems. Overheating of the engine can create thermal damage that affects internal components. Overheating of the battery can create internal short-circuits.
It is important to make sure your vehicle battery is properly maintained. Properly testing them helps prevent electrical problems. There are many different kinds of battery load testers. Here is a look at some of them:
Interchanging Batteries in Your Car Starting System - Sometimes the electrical charging system for your car or truck is changed, and that changes the battery charge system as well. If you have your vehicle charged by a different type of alternator, it may be necessary to change the batteries as well. If you have a secondary starting system, the alternator can be changed by wiring it up with a new battery. This kind of battery load tester allows you to do this.
Battery Load Testers for 12Volt AC - Most 12Volt AC vehicle batteries are sold in package sizes of either AA or triple A. In addition, most are sold with a charger that needs to be connected to an outlet. This charger gives the user the ability to visually check the battery load capacity and charge rate. This kind of battery load tester allows you to view details like voltage and wattage. It also has an alarm that signals when the charge has reached the maximum limit.
AC Voltage Stabilizer - An AC voltage stabilizer is designed to keep the battery from having to rapidly charge and to prevent the alternator from being burned out. It is usually located on the circuit breaker box side of the charging system. To use this kind of load tester, you must have an ohm meter. To test the stability of this product, you should place the device in an open area.
AC Voltage Stabilizer testers - The AC voltage stabilizer is built differently than other testers. It does not require any leads or wires. The device uses high tech resistance tests to test the alternator and the lead acid batteries for stability. These devices often times have a time limit so that if it detects a fluctuation, it will tell you to replace the unit immediately. This is one of the most reliable testers on the market.
The above mentioned testing devices are all available in different styles. Each has its own benefits as well as drawbacks. If you are looking for a quick and easy way to test your batteries and your equipment then you definitely want to consider buying a battery load tester. These products are a must have in every electronics shop. You can buy them online at great prices.
Some of these battery load testers have a LCD screen that will let you know what the test results are. If there is a drop in output or if you are seeing a fluctuation in power, this is a good indication that your battery is suffering from a condition. Once you purchase a product like this you will never have to worry about dropping dead batteries again. No more mystery as to why your equipment is giving you dead batteries.
Another great feature of the battery load tester that we talked about previously is that it works just like a circuit breaker. If the voltage at the starter motor drops below a certain point, the circuit breaker will trip, supplying electricity to your lights and other items that are draining your battery. If you test your equipment regularly then this is not going to happen. When this happens you need to replace the battery quickly.
The best battery load testers are those that allow you to test multiple batteries all at once. With this capability you can keep up with your inventory by knowing exactly what battery's are low and what ones are charging. This can help you make smart decisions as to what to charge in order to get the most out of your equipment. If you have multi-battery tester make sure you buy the one that is capable of monitoring multiple batteries simultaneously.
