## Long description

The CTEK 40-133 Battery Tester is a compact tool for checking 12V lead-acid batteries. It combines an easy-to-read charge indicator with a quick-connector solution that simplifies testing when battery terminals are hard to reach. The tester is supplied with an M6 eyelet terminal and a 55 cm cable for remote connection and includes a 15A fuse. The product comes with a 2-year warranty.
Advantages
The integrated indicator provides a clear visual display of battery charge level, enabling fast assessment of battery condition. Eyelet terminals (M6) allow permanent or semi-permanent fitting to the battery so the tester can be used without direct access to the battery posts. The 55 cm cable gives flexibility in positioning the indicator for easy viewing, and the included 15A fuse offers basic circuit protection.
Suitable for
 Testing 12V lead-acid batteries in cars, motorcycles, and small vehicles
 Situations where battery terminals are difficult to access
 Workshop or home use for quick battery checks
Key specifications

 Fuse rating: 15 A
 Designed for: 12V lead-acid batteries

How to use
Fit the M6 eyelet terminals to the battery posts and secure them according to the battery manufacturer’s guidance. Position the indicator where it is easy to read and route the 55 cm cable safely to avoid moving parts or hot surfaces. Turn on the indicator or follow the device’s startup procedure to read the battery charge level and status. Interpret the display to determine whether the battery requires charging, further testing, or replacement.
Usage recommendations
Use the eyelet connections to keep the tester ready for repeated checks. Inspect the cable and fuse before each use, and replace the 15A fuse with the same rating if blown. Avoid exposing the tester to excessive moisture or extreme temperatures; follow basic safety practices when working with vehicle batteries, including removing metallic jewelry and wearing eye protection when necessary.
