13 best battery load testers

A battery load tester is a diagnostic tool used to assess the condition and performance of automotive and other types of batteries. It provides valuable information about the battery's ability to hold a charge, its voltage under load, and its overall health. Here's what you need to know about battery load testers:

  1. Battery Testing: The primary function of a battery load tester is to assess the condition of a battery. It accomplishes this by applying a controlled electrical load to the battery, simulating the demands placed on it during vehicle start-up and operation.

  2. Voltage Measurement: Load testers measure the voltage of the battery under load. This means they evaluate the battery's performance when it's delivering power, which can reveal issues that might not be evident when the battery is at rest.

  3. Cranking Amps (CA) and Cold Cranking Amps (CCA): Load testers often display the battery's cranking amps or cold cranking amps rating, which indicates the battery's ability to deliver a burst of power during engine start-up. This information helps determine if the battery is suitable for a specific vehicle.

  4. Voltage Drop: The tester checks for voltage drop during the load test. A significant voltage drop under load can indicate a weak or failing battery.

  5. Pass/Fail Indicator: Many battery load testers have a simple pass/fail indicator, making it easy for users to determine whether the battery is in good condition or needs replacement.

  6. Testing Different Battery Types: Battery load testers can be used to test various types of batteries, including lead-acid, AGM (Absorbent Glass Mat), and gel batteries commonly found in automotive applications.

  7. Maintenance and Preventive Checks: Load testing can be part of routine battery maintenance and preventive checks.It helps identify battery issues before they cause starting or electrical problems in a vehicle.

  8. Diagnosing Starting Issues: If a vehicle is experiencing starting problems, a battery load tester can help pinpoint whether the issue lies with the battery or other components in the electrical system.

  9. Safety: Battery load testers are designed with safety features to protect the user and the vehicle. They typically have built-in circuit protection and other safety mechanisms.

  10. Portable and Easy to Use: Most battery load testers are portable and easy to use, making them suitable for automotive professionals, DIY enthusiasts, and roadside assistance personnel.

  11. Regular Testing: It's a good practice to periodically test the battery's condition, especially in extreme weather conditions or after the battery has been in use for a few years. This helps ensure reliable vehicle starting and electrical performance.

Battery load testers are valuable tools for assessing the health and performance of automotive batteries. Regular testing with a load tester can help identify battery issues early, potentially preventing unexpected breakdowns and extending the life of the battery.

User questions & answers

Question: Will this test my alternator
Answer: No. It will only test a battery
Question: will this work on 8 volt golf cart batteries
Answer: Hi Cabo, It might as it has scales for 6 or 12 volt. It would read a little high on the 6 volt scale when checking 8 volt. I can't promise it will work though.
Question: As this tester puts a 130 Amp load on the battery being tested, is that too much load for testing small batteries such as motorcycle & lawn tractors
Answer: Hi R.W., this tester will certainly tell you if smaller batteries are in good shape but it is kind of over kill as it works by resistance testing. Kind of like plugging a toaster onto your battery. It will draw a lot of juice off the battery in just one test with smaller batteries so if they are weak you will know it fast and they will likely need a recharge afterward. I use it for 4 and 8 D size batteries for starting large diesel engines. I would suggest a lighter amp load tester for what you are doing. Something around a 50 amp range.Hope this [email protected]
Question: does this work on a 12 V 8D diesel truck battery
Answer: This will work on all batteries 12 volts and less A carbon pile tester would be a better choice for the larger 8D battery

Question: Is the switch momentary or does it stay on
Answer: The switch is just to test the load on the battery it is spring loaded and stays in the off position .
Question: Is this made in america
Answer: i'm sorry to say, this is not made in america. that was the first question i had when i went to replace my old one.ther are only a few that are made in usa and they are more than $300. so they got us over a barrel, you buy this one for under $50 or the next one up is $300. that's what they mean when america does make anything anymore. we do make stuff, but its huge money and priced right out of the market. the us govt needs to step in, tax the crap out of this south east asia stuff so the price would be $150, then the us companies could compete cause they could sell alot more at a lower price. but the us companies dont see those kind of sales numbers, so its hard to compete in a free trade market. so, all in all, the answer is no.
Question: This is the same unit they sell at harbor freight for 20 bucks right down to the switch, do your self a favor and buy the schumacher instead. tom

Question: Will this work on 8 volt golf cart batteries
Answer: Yes
Question: Se puede comprobar la carga de una beteria de ups de 12 v 7amph o una bateria de 6v 5 Amph
Answer: Entiendo que este equipo está diseñado para probar baterías de uso automotriz. Aunque el fabricante no detalla la magnitud de la resistencia usada para la prueba, es de suponer que es lo suficientemente grande para emular el arranque de un automóvil. Tal resistencia exigirá demasiado de una batería de bajo amperaje, y por tanto siempre aparecerá como debil en la prueba. Yo usaría un simple probador o tester para esas baterías de pocos amperios.
Question: volt golf cart battery tester

Cranking Test

The cranking test is used to test and analyze the actual required cranking current and cranking voltage to check the starting motor works properly or not. The test result displays cranking time, voltage, and status. If the stating malfunction may cause an increased starting loaded torque; or rotor friction of the starting motor generates increasing friction of the starting motor itself

Charging Test

Charging test is used to check and analyze the charging system (generator, rectifier, rectifier diode, etc.) status, displays load voltage, unloaded voltage, ripple status, charging system status, thus to find out whether the output voltage of the generator is normal, the rectifier diode works properly or not, which avoids damaging the battery and shortening its life greatly due to overcharging or incomplete charging.
