Battery Type Identification and Testing Slots
The tester features multiple dedicated slots and a test probe for various battery types. Refer to the diagram below to identify the correct testing location for your battery.

Figure 4: Battery Type Testing Slots. This detailed diagram illustrates where each specific battery type should be placed or connected for accurate testing.
Testing Procedure
To test a battery:
- Identify the correct slot or contact points for your battery type using Figure 4.
- Ensure the battery terminals are clean and free of debris.
- Place the battery firmly into the designated slot or press it against the contact points, observing correct polarity (+ and -). For batteries requiring the test probe, connect the probe to the battery's positive terminal and the negative terminal to the corresponding contact on the tester.
- The LCD display will show the battery's energy content in percentage and its voltage.

Maintenance
Cleaning
To ensure accurate readings and prolong the life of your tester, keep it clean. Wipe the exterior with a soft, dry cloth. Periodically clean the metal contact surfaces with a cotton swab lightly dampened with rubbing alcohol to remove any residue that might affect conductivity.
Storage
Store the Ansmann Energy Check LCD in a cool, dry place away from direct sunlight and extreme temperatures. If the tester will not be used for an extended period, it is recommended to remove the 9V battery to prevent leakage.
Troubleshooting
- Tester does not power on:
Check if the 9V battery is correctly inserted with the proper polarity. Ensure the 9V battery itself has sufficient charge. Replace if necessary.
- Inaccurate or inconsistent readings:
Ensure the battery being tested is making firm and clean contact with the tester's terminals. Clean the battery terminals and the tester's contact points if there is any visible dirt or corrosion. Ensure the battery is placed in the correct slot for its type.
- Display shows 'LO' or 'ERR':
This may indicate a very low battery charge or an incompatible battery type. Verify the battery type is supported by the tester.
