Getting started

Warning – Batteries

  • When inserting batteries, note the correct polarity (+ and – markings) and insert the batteries accordingly. Failure to do so could result in the batteries leaking or exploding.
  • Only use batteries (or rechargeable batteries) that match the specified type.
  • Before you insert the batteries, clean the battery contacts and the polar contacts.
  • Do not allow children to change batteries without supervision.
  • Do not mix old and new batteries or batteries of a different type or make.
  • Remove the batteries from products that are not being used for an extended period (unless these are being kept ready for an emergency).
  • Do not short-circuit batteries.
  • Do not charge batteries.
  • Do not throw batteries in a fire.
  • Keep batteries out of the reach of children.
  • Never open, damage or swallow batteries or allow them to enter the environment. They can contain toxic, environmentally harmful heavy metals.
  • Immediately remove and dispose of dead batteries from the product.
  • Avoid storing, charging or using the device in extreme temperatures and extremely low atmospheric pressure (for example, at high altitudes).Remove the cover of the battery compartment at the rear and insert an AAA battery in the correct direction. The tester is then immediately ready for use.


Only one battery/rechargeable battery can be tested at a time. The voltage remaining in the battery is shown in the LCD display.

  1. Select the test slot in accordance with the size of the battery or use the corresponding shapes of the housing. The corresponding battery type names are imprinted on the housing. Insert button cells with the positive pole facing upwards.
  2. Ensure that the polarity is correct and the contact is secure. Do not insert batteries at an angle. Button cells must touch the side test contact.
  3. The LCD bar graph shows the residual voltage value of the battery tested.


I—-1 to 5—-IBatteries: Dead – replaceRechargeable batteries: Already deep-discharged – charge immediately. You should avoid discharging the rechargeable batteries this far.

I—————I—– 6 to 11——-IBatteries: Weak, little power left. Only usable in certain circumstances in consumers with low power requirements e.g. clocks etc.Rechargeable batteries: Recharging point reached – recharge as soon as possible.

I—————I——————–l——-12 to 18——-IBatteries: Ok, energy remaining is sufficientRechargeable batteries: Due to the lower cell voltage, rechargeable batteries only reach 13/14 bars when fully charged.

Indicator drops quickly: Battery/rechargeable battery is defective and should no longer be used, e.g. high internal resistance during testing.

Do not use leaking/damaged batteries. Remove the test battery from the device after testing – do not perform continuous battery life testing.
