Product Description
Why You Need A Car Battery Tester?
On a cold morning when you are rushing to work, but the car failed to start? The cause of this may be a flat battery. When your battery runs down and can’t start your vehicle, it’s important to determine if it’s drained and needs to be recharged, or it’s too weak to hold a charge.

Battery Health TestAccurate and speedy. Once you connect this 12V battery tester to battery terminals, you’ll get the readings of CCA values/ratings, voltages, internal resistance, state of health (SOH), and state of charge (SOC) in 3 seconds, with concise results like “GOOD, BAD, REPLACE, or RECHARGE” for quick checkups. |
Cranking TestIf your car battery is 4 or more years old, this battery tester helps predict if the battery will fail to start the vehicle. The BT50 will show you the cranking time in milliseconds, and record the lowest voltage that the battery is able to maintain while the starting motor is working. If the result is < 9 volts, you need a battery replacement. |
Charging TestIf you find the engine has difficulty continually running while traveling, switch this load tester to the charge testing mode with the vehicle running. If the battery and alternator are good, the result should be between 14.2~14.5 volts. Lower than this means your alternator or parts of the charging system need to be investigated. |

Data ReviewThis car battery tester gets answers fast. It can automatically record the most recent test result. This way you’ll easily get the previous data to avoid the retest from the scratch and keep the battery health logs or share the information with others. |
3 Safety FeaturesSafety risks are minimized during use thanks to the Spark-Proof Connection – saving you from the possibility of a fire; Reverse Polarity Protection - prevents damage if the battery clamps are connected to the wrong terminals; Overheat Protection - automatically shut the tester off when reaching the temperature limit. |
User-OrientedThis 12V car battery monitor requires minimal instruction due to the intuitive interface. The 4-button keypad makes for easy navigation. The large, backlit 2” LCD shows crisp data even under direct sunlight. Its compact size makes it ideal to keep in the glove box or in the tool box. |
Easy Steps. Ready and Go!
This car battery tester is ready to work right out of the box. It’s simple, straightforward, and requires no setup. Operating is a breeze:
1. Turn off the ignition, accessories, and loads.
2. Make sure the battery terminals are clean.
3. Correctly connect the clamps to the battery terminals (Red “+” to Positive; Black “–” to Negative).
4. The BT50 will power up once it gets connected to the battery you’re testing and is ready to function.
Notice: If the battery voltage is lower than 8V, the BT50 stops the test and displays a message indicating low voltage. Please charge the battery and test again.
The battery monitor will show you one of the following results in minutes:
- GOOD BATTERY: The battery is in good condition.
- GOOD, CHARGING: The battery is good but has a low current; it needs to get recharged.
- REPLACE: The battery is almost dead, or there is a poor connection between the battery and the tester. Replace the battery or test it again. An out-of-vehicle test is recommended for a second test.
- RETEST AFTER CHARGING: Fully charge the battery and retest it. If the same reading occurs after the battery is fully charged, replace it.
- BAD CELL, REPLACE: The battery is broken, interiorly damaged, or has short circuit. Replace the battery.
