Precise 4-point battery internal resistance tester up to 100 volts YR-1035+
The YR1035+ is a 4-point precise measuring device for measuring the voltage and internal resistance of lithium (Li-Ion, LiFePO4, LiMn, LiPo), NiMH & NiCd and lead batteries as single cells or battery packs up to a maximum of 100V. The measurement and long-term monitoring of the internal resistance allows a convenient quality check of new batteries and also simple documentation of ageing during long-term use. You can use the battery tester to check freshly delivered batteries and sort out inferior batteries.
Measuring the internal resistance helps when assembling battery packs or when “marrying” batteries for use in parallel or series connection. Counterfeit batteries can often be recognised by their excessive internal resistance. The measurements are quick and reproducible.
Four-point measurement method: This method is based on the four-wire method and was developed to eliminate the influence of contact resistance. It is based on two quasi-separate circuits.
Suitable battery holders: XS10-4
Suitable crocodile clips: K-XS1-4

To achieve the best measurement results, we recommend the following:
Clean the battery contacts, charge the battery, leave for an hour to return to room temperature and then test several times. Touch the battery as little as possible to minimise the temperature rise from your body heat.
