Review: Great meterxz - The HRM-10 works quite well to check batteries. To utilize it to its fullest, the batteries should be checked when new or referenced to a new battery of the same type. A second use for the HRM-10 is to use it as a milli-ohm meter. Even with no battery connected, it will measure resistance in the milli-ohm range. It's great to check connections or check very low resistances.
Review: Great meter - The meter works great. I had no problem checking the voltage on my batteries but checking the resistance is very difficult with the leads that came with it. The leads are not the problem, it's holding the battery still while making sure you have the proper contact. I highly recommend that you buy the version that has the cell holder with it. It makes a huge difference.

## Questions & Answers

**Q: Why can the measurement of internal resistance be a good or bad sign for a battery?**
A: The battery will be damaged during use, the capacity will decrease and the internal resistance will increase. The lower the internal resistance of the battery, the better the performance and the higher the load capacity.

**Q: Does the battery need to be fully charged for measurement?**
A: The internal resistance of a battery is usually different when it is fully charged and when it is low. When the battery is fully charged, the internal resistance is usually lower. When the battery is low, the internal resistance is usually higher.

**Q: Why are the measurements unstable?**
A: There is poor contact between the test clip and the battery, or there is a strong background noise.

**Q: Why is the measured internal resistance higher than the battery internal resistance?**
A: The internal resistance of a large capacity battery is very low. The internal resistance of the battery electrode or wire is often higher than the internal resistance of the battery.The clamp needs to be in the correct position to get accurate data.

### ⭐⭐⭐⭐ Accurate battery tester
*by D***1 on October 11, 2025*

Excellent battery tester. I also use it to for resistance testing but I get mixed results- like trying to identify the gauge of a jumper cable. Apparently this type of connection (4 wire Kelvin) has trouble with stranded wire. I'm still trying to figure this out. Again, for battery testing it works great. Voltage accuracy is spot on. The fact that it has resolution down to micro ohms is fantastic when working with a battery with less than 1 milli ohm per cell. (SMC-SRD)
