How to Measure Silver Oxide Battery Voltage with a Multimeter
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 use two years, when it comes to the monthly charge on the throw, where the dead button battery voltage at 1.2V can be charged after available, with an old cell 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 clamps to clip the 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 is still close to the voltage value, the actual it can not carry the watch micro-current work, so the voltage is also counted as a false information, the measurement is not consistent with the use.
Pointer multimeter measurement of button battery, flow through the head of the micro-filament 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.
3, how to measure the multimeter button battery?
a. Insert the red pen into the lower left "10" jack,
b. Insert the black pen into the left lower "one" COM jack,
c. Turn the dial of the pointer multimeter to DC,
d. Measure the soybean-sized watch battery, the arrow pointing to 2.5V
e. Measure the battery of a 2-cent coin, point the arrow to 10V,
f. Battery flat large surface in the next, with a red pen touch, black pen touch the center of the small disc, the center of the circle around the groove, is the positive and negative insulating compartment, the pen's metal head must not slip into the groove caused by a short-circuit discharge.
g. Look at the needle readings, the right end of the table head up and down three readings, the top down for 250, 50, 10, you will 250 this reading 100 times smaller, the amount of 1.5V battery when the 250 as 2.5V range.
h. Measurement of 3V button battery, look at the table directly on the 10 range!
Learn to use the multimeter, to first learn how to read from the head of the table, range selected large, the reading is too small, range selected small pointer will hit the top of the broken head.
