1. Schumacher BT-100 Battery Load Tester

Schumacher BT-100 Battery Load Tester

Using an analog indicator, this battery load tester has a 100-amp load test capability that makes it suitable for 12V car batteries. This means that it is also suitable for batteries with a lesser voltage, such as 6V batteries, testing for up to 50 amps. Accurate measurement is assured with a needle that points to pre-indicated amperage points once the tester is connected to the battery with the two clamps fitted onto it. Apart from testing a battery’s load, the Schumacher BT-100 also tests the battery’s condition and starter motor draw. The tester can also be used to perform a complete charging system diagnosis. Its steel case, with a baked-enamel finish, is strong enough to protect the shock-resistant meter, all elements that serve as proof of the tester’s overall quality and durability. The battery clamps firmly grip where they should, the handle is rubber insulated, and with a top-mounted rocker switch, using this handy device is also very easy.

Pros

  • Multiple testing capabilities
  • Complete diagnosis capability
  • Easy to use

Cons

Measurement accuracy not highest

Summary

Because of its mechanical reading method, measuring to a decimal point isn’t possible, but there is plenty more to take from a device that excels in every other feature expected from a car battery tester. Suitable for most car batteries, its design also takes steps to make it easier for users with little to no experience.

 

 

2. Associated Equipment 6031 Battery Tester

Measuring 6.3” x 6.4”, this relatively compact battery tester comes in handy when needed, as is evidenced by its size and functions. Once its two battery clamps are fixed in place, this AC tester can check for defective alternator diodes, including taking a GM trio test, the results of which can easily be read on the analog display that can show up to 125 amps. This tester also checks starter current and AC/regulator output voltage, suitable for 6V and 12V car batteries. The recessed meter ensures accurate readings, as well as helping protect against damages that may be incurred when in use.

Pros

  • Compact
  • Strong clamps
  • Multi-functional
  • High amp testing capability

Cons

No handle and hard to stand alone

Summary

Giving just how small this device, its capability to handle high voltages and amperage is surprising, and it does this in a way that makes life easier for the user.

 

 

 

3. Pulse Tech Xtreme Charge Quick Battery Tester

 

With indicator lights such as “good” and “bad,” testing your car battery’s condition could not be made easier, helped by the fact that the hand-held battery tester measures only 7.2” x 1.6” and weighs a mere 1.6 oz. It is made to test 12V batteries and alternators, the results of which are displayed in 4 stages along equally divided percentage lines, from 0% to 100%. A unique feature of the Pulse Tech battery tester is the leave-on charging cable set that allows for remote battery testing. Other than just how easy it is to use, the battery tester ensures that testing is done as quickly as possible, not to mention all the safety measures the design offers.

Pros

  • Small and light
  • Easy to use
  • Removable NEG probe tip
  • Good or bad alternator output LED indicators

Cons

Does not measure amp and voltage

Summary

Suited for a quick check of your battery’s condition, this tester sacrifices precise numbers for a convenience that many will appreciate, especially those on the go or those who just need to keep a regular check on a battery they do not entirely trust.

 

 

4. Sunpro Actron CP7612 Battery Load Tester

Sunpro Actron CP7612 Battery Load Tester

The Sunpro Actron battery tester has a typical design, except that the analog display is fitted at the bottom of the chrome-plated steel piece, rather than the top. By connecting the two clamps it comes with, users are able to perform a voltage test on both 6V and 12V batteries, as well as a 15-second battery load testing. The color-coded scale has a voltage range from 0-16, and is clear enough to read properly when testing the 100-amp load-testing capability. Made from a rather heavy-duty material, the tester is resistant to a lot of conditions that would otherwise wear it down, making it highly durable.

Pros

  • Chrome coating
  • Easy to read display
  • Large clips
  • Suitable for 6V and 12V batteries

Cons

Lacking safety measurements

Summary

Though not all it could be, the Sunpro Actron is definitely one of the better analog battery load testers available, and that evidence not just by what it can do, which is plenty, but how well it does it. A great pick for those who want to delve just past the “good” and “bad” in search of more precise numbers and a more specific overall reading of their battery’s condition.

 

 

5. OTC Digital Battery Load Tester

OTC Digital Battery Load Tester

When it comes to accuracy, no battery load tester can be more precise than a digital one, and that is exactly what the OTC battery load tester claims to be. This 130-amp device displays voltage readings of both 6V and 12V batteries with its digital display that is both accurate and easy to read. Its other functions include testing the state of charge, an alternator ripple test, and starting and charging system tests. Features such as an alternator test lead, ripple detection light, and its 0-16 volt range only add to what is an already multi-functional device. Other than its various functions, what makes this device special is in just how compact and easy to handle it is, fit with an easy-to-grip handle, and its light weight also goes a long way in helping users.

Pros
