Anyone else use the tongue method when testing 9 volt batteries? When I was a kid, someone taught me that you can test a 9 volt battery by touching it to your tongue. You'll feel a charge if there is any juice left in the battery. Been doing it ever since. That might explain a few things. lol
Here you see 20ea of the NiMh modules from a Toyota Prius made into a 14.4vdc nominal battery. The Ah of this pack if brand new would be around 65Ah. Being these are used from a 2002 Prius, I don't know the exact Ah left in them, but they seem to be holding a good charge at the moment.
Learn, Why we can't have large NiMh batteries for Electric Vehicles or anything else for that matter:
Search - "Patent encumbrance of large automotive NiMH batteries"
Send the link to your state's represenatives. Voice how this technology needs to be released for continued development. My worry is something like this might happen with the new Lithium Battery technology.
The above link, is why I don't suggest doing business with GM, Texaco, or Chevron, as they all had a hand in suppressing the development of EV's.
There's a button on the back of the MB-21 grip to check battery power from the six (!) AA batteries the F4 takes.
Wanted to see what the "Internal Resistance" of the reconfigured Toyota Prius battery modules worked out to be.
This digital analyzer shows the pack to be at 16.3vdc, with an internal resistance of 16.02milli-ohms.

Did some testing of the batteries in my external flash to see if they needed charging.
From time to time terminals appear that give the bell and one of those that in our opinion achieves it in this 2021 is the VIVO V21 5G. We have tested what this device offers in the autonomy section, and the truth is that the results are much better than anyone might think.
When verifying that t...

Battery board that connects to the Arduino Controller board.
Two of these can be connected to each controller allowing 8x 18650 batteries to be tested independently.
Each board has 4x identical channels. For each channel:
CHG input is a 4.2V reference from the control board which sets the max terminal voltage of the cell. The 'A' op-amp regulates the voltage to the battery by adjusting the gate drive of the MOSFET. The series resistor provides a crude current limit during charging.
The 0 Ohm resistor allows the PCB layout to be easily customised to allow the op-amp inverting input to be connected at the battery terminal rather than into a generic power plane.
The PNP transistor turns on when the base-emitter voltage is 0.65V. This is true until the current through the upper series resistor is less than ~ 60mA. When the current drops to this point the PNP turns off causing the SENSE voltage to drop to 0V.
DISCHR connection is the logic high output from the control board that enables the constant current discharge circuit. When the logic input is low the discharger is disabled. When the logic input is high the 'B' op-amp regulates the voltage across the lower series resistor to be ~1V. 1V across the series resistor sets the current through the resistor to be a constant 100mA. The potentiometer allows trimming of the current.
The Arduino times how long it takes for the battery voltage to fall to the end of discharge voltage. The time (in hours) x constant current (in mA) gives the battery capacity (in mAh).
Supposed 'genuine' Canon LP-E6 from eBay HK seller.
This battery was supplied in a Canon box and had all the appropriate markings to suggest it was genuine. The test results show otherwise.
Blue trace shows the battery voltage during discharge from full. Discharge is a constant current.
Red trace shows the cumulative capacity extracted from the battery. The maximum value of the red trace shows the total capacity extracted from the battery over the discharge test.
It can be seen that this 'genuine' Canon LP-E6 provided a capacity of just over 1270 mAh or 70% of the quoted capacity on the label. Compare that to the results from the real genuine battery that came with the camera.
The plot shows the result of 4x separate discharge tests. The results are within 3 mAh of each other.
Arduino based multi battery tester. Can test up to 8x lithium ion 18650 batteries independently.
U5 and U6 are serial to parallel converters connected to the SPI port of the Arduino. U2 is a parallel to serial converter connected to the same SPI port.
U5 controls enabling the charger for each battery, U6 controls the constant current discharge circuit for each. Both charger and discharger are located on the battery board.
U2 Reads the Sense inputs from each battery. The sense input is a flag to say when the charging current is below a certain threshold, indicating charging is complete.
U3 and U4 each contain 4x independent analogue switches which are used to connect the 4.2V reference through to the respective charger circuit for a particular battery. On the battery board the reference input to the charger has a weak pull-down resistor. When the switch is opened the charger is set to 0V, disabling the charger for that channel.
Each battery board has 4x channels. Two of these battery boards can be connected to the control board. These connect via J2 and J3. The DETECT pin is grounded on the battery board and using a pull-up on the Arduino input allows the board connection to be detected.
The LCD is 3.3V, so all signals are level shifted by the resistive divider network.
U7 is a precision 2.5V reference source, which is buffered and amplified by U8. The potentiometer is used to adjust the 4.2V reference output. This output is switched using the analogue switches to control the chargers for each battery and also is supplied to the ADC reference input on the Arduino.
Arduino will detect a battery being connected by the ADC registering a voltage. This triggers a charging cycle to begin. That continues until end of charge is detected by a logic low on the SENSE input.
Once charging is finished the battery is rested for a few minutes before a timed, constant current discharge cycle is begun. The discharge current and time to end of discharge allow the capacity of the battery to be calculated. This is displayed on the LCD and logged for download over USB to the PC.
Once the discharge is completed the cell is part charged to prevent it being left fully discharged.
Once the detected voltage drops to 0V the Arduino resets that channel and the whole process can start again when the next battery is connected.
This battery was sold as a compatible clone with a claimed capacity of 2100mAh, 16% more than the genuine, original Canon part.
The results show it is terrible. Measured capacity was under 600mAh or 33% of the real thing and 29% of the claimed amount.
Hardware improvements aren’t the only route to better batteries. Test systems can also help to evaluate the overall system design and optimize its performance. See what else can help develop better battery modules and packs.
