Will 1.2 V batteries work instead of 1.5 V?

Q : Can I use 1.2 V rechargeable batteries in devices that usually take 1.5 V throw away batteries? Yes, most definitely. Using 1.2 V rechargeable batteries will have no effect on the use of the equipment. In fact an alkaline battery only benefits from 1.5 V voltage at the beginning of its discharge.

At what voltage is a NiMH battery empty?

4 Answers. NiMH cells start at about 1.5 V right when fully charged, drop to about 1.2 V most of their discharge life, and are pretty much empty at 900 mV. Stopping there is usually safe.

How do you rejuvenate NiMH batteries?

Here’s what you need to do:

  1. Step 1 – Charge the NiMH batteries fully. Remove the batteries from the device and put them in a charger.
  2. Step 2 – Discharge the NiMH batteries fully. After the battery gets completely charged, it’s time to completely discharge the battery.
  3. Step 3 – Repeat the two steps again.

How do you revive old NiMH batteries?

Old NiMh cells internally have crystalization that forms between the positive and negative plates. In order to revive the cell you have to shock the battery and break the short that the crystalization creates. There used to be some chargers that had a dead cell revival mode if you can find one.

Why there are no 1.5 V rechargeable batteries?

The NiMH cells will be providing 1.2 volts throughout it’s cycle use while alkaline cells go from 1.6v to 0.9 volts. Alkaline cells have a variable voltage which hardly makes them 1.5 volt batteries when they don’t hold 1.5 volts for 80\% of it’s cycle life.

What is the charging voltage of the NiMH battery?

I found the charging voltage range 1.4V to 1.6V in Wikipedia in reference to Panasonic NiMH manual and handbook. But upon checking the handbook, it did not mention specifically about the charging voltage.

What is the difference between alkaline batteries and NiMH batteries?

The main difference is that an alkaline battery starts at 1.5 volts and gradually drops to less than 1.0 volts. NiMH batteries stay at about 1.2 volts for almost 80\% of their discharge cycle.

What is the voltage of a Ni-Cd cell?

The open-circuit voltage is 1.4 volts, dropping to 1.2 volts during discharge. Ni–Cd cells have a nominal cell potential of 1.2 volts (V). …a Ni–Cd cell’s terminal voltage only changes a little as it discharges.

What is the nominal voltage of a rechargeable battery?

Not all rechargeable batteries have a nominal voltage of 1.2V; it is specific to a few chemistries that happen to be popular. According to Wikipedia, the following rechargeable battery chemistries have cell voltages of 1.2V:
