Battery Load Tester
What are your battery load tester options?
If you own a car or motorcycle, a boat or an airplane or even large, heavy construction equipment, then you need to have a battery load tester available at all times. Having a proven system will give you an accurate reading you can rely on. Simply put, You need to know if you can use the battery you have or if you should replace it with a new one.
Battery load testers come in all shapes and sizes and depending on the size and level of volts you are testing will depend on what size you will need. There is one proven UPS battery tester No matter what type of ups system you are looking to test, there is now a solution you can count on. For the batteries of 3-140 AHR the SOC will provide readings that are the same as full discharge. For any of the larger type, unsealed, a hydrometer should be adequate to attain specific gravity. The VRLA or the sealed lead acid VRLA SLA, VLA, AGM and the like are more complicated and thus harder to get an accurate reading and specific gravity is just not an option.
You want to use a device for health analysis of your battery that contains a specific load application. Put simply, the load applied will be commensurate with the batteries power ability. If you do not use a load specific device when you load your battery, you may experience false positive readings on weak batteries and this could lead to many problems down the road. A proven battery tester that applies a precise load and compensates for temperature variance will make all the difference in the world. Many of the battery load devices without this feature will pass a weak battery, because they are not exercising the batteries potential during the test. Many other testers will only asses the voltage and not even apply a predetermined load. If there is any voltage whatsoever the tester will give a false positive and false sense of security to say the least.
You want a device that is sturdy, rugged and will last in the field. A durable metal and the newer plastics available today can withstand most of the torture technicians and mechanics put their equipment through. However you always get that one guy that tosses the thing off the roof. Not much you can do about that. Almost all standard equipment manufactured today is also water proof or at least water resistant. Depending on your selection you may have a panel range to perform adjustments of 900 CCA to 1200 CA and up to 125 degrees in temperature to adjust the temperature controls. As an alternative the settings may be in AHR or Ampere Hours. All of this is dependent on which brand and style you decide to purchase and for what battery you are going to be testing.
If you purchase and use a battery load tester that gives you a pass/fail reading or a gauge that has a dial and a pointer, there is just too much unforeseen room for error. Make sure your choice is one with manual adjustments for load, temperature compensation and the appropriate ampere hour or cold cranking amp setting. Without the manual setting of these variables, there is just too much room for mechanical error. This is the recommended industry standard battery load tester
