How to use a multimeter to measure the voltage of a silver oxide battery
Our common button type small white bright battery, where the authentic battery inside the material is silver oxide, where the fake are replaced by lithium ion, you can not identify. There are also although the real thing, but some of them are dealers hands of the old goods, close to or has expired the battery to your watch or erhu calibrator will not stand up to use.
1, silver oxide battery experience:
Where measured 1.5V or 3V button battery, charged once, the watch can also work for several months.
How to charge, higher than the battery 1V, too high hot flow liquid bulge on the waste. A little bit of heat to work, the shell is cold for not into the electricity. I have an electronic watch, take it out to charge after the downtime, can also be used for two years, when it comes to the monthly charging on the throw, where the dead button battery voltage at 1.2V can be charged after available, with an old mobile phone charger, cut off the plug, series with two-plate tube step-down voltage according to the need to be higher than the original battery of 0.5V charging button battery. Use a clothes drying wooden clamp to hold two threads to charge.
2, what type of button battery multimeter to measure the voltage?
＊Don't use a digital meter to measure ⚠️ Why?
Digital meter picks up the weak signal amplification data, measurement of the battery only weak current power supply, on the internal resistance is large, the battery has been scrapped, the presentation of the voltage value is still close to the co-operation, in fact, it has been unable to carry the watch micro-current work, so the voltage is also considered to be a false information, the measurement is not in line with the use of the measurement.
Pointer multimeter measurement of button battery, flow through the head of the micro-filament of the working current is much larger than the watch's power consumption, in this case the amount of battery power are real, mounted on the table will not be reduced to the measured voltage data. Where up to 1.2V battery, loaded into the watch does not turn, because the pointer watch without a certain power is unable to run.
