Even a freshly charged NiMH should report well below 100% (I haven't tried yet). But they're going to report odd figures because the devices are designed to use alkalines. And of course you can use them for a low-drain item like this. Now fully charged NiMH batteries are going to be above 1.2V also. Of course the voltage will be lower while the battery is being drained, but that's not too relevant here because these controllers are very low draw. The left one is nearly dead at 10% and reads 1.29V. The HMD is reporting the right one at 40% and it is reading 1.41V. I pulled the two original batteries from my controllers right now to check them. They very slowly degrade through 1.5V and towards 1.4V.Īn alkaline battery that reads 1.2V is ready for the trash bin. Go get yourself some to save money and reduce e-waste.īrand new 1.5V alkaline batteries are actually normally around 1.6V or so. TL DR: 1.2v rechargeable batteries are perfectly usable with Quest controllers. That's because battery life estimates are usually crude approximations based on discharge curves and are often calibrated for non-rechargeable batteries. Devices intended to operate from alkaline cells are designed function until the voltage per cell drops to about 0.9 volt or lower (at 500 mA for AA cells), so no you aren't undervolting your controllers if you use rechargeable batteries.Īside: When using rechargeable batteries, you might notice that battery life will show about 80% until they suddenly drop to 0%. While there are some devices that are only specifically designed to work with alkaline batteries, the vast majority of electronics will work just as well with 1.2v NiMH cells. Once alkaline batteries discharge to 50% capacity, it will usually be delivering a lower voltage than a NiMH battery. NiMH batteries stay at about 1.2 volts for most of their discharge cycle. The main difference is that an alkaline battery starts at 1.5 volts and gradually drops to less than 1.0 volts. Here are several graphs comparing the voltage output of different batteries as they discharge at different loads: Īs you can see, alkaline batteries actually average about 1.2 volts over their discharge cycle. ![]() 1.5v and 1.2v are nominal voltages, which is basically a value assigned to a circuit or system to designate its voltage class. The voltage drops as the battery discharges, and it also drops due to internal resistance as the load increases. In actuality, a cell doesn’t deliver a constant voltage. The common misconception is that alkaline cells deliver 1.5v and NiMH cells deliver 1.2v. I've seen several myths being posted about this around here and I thought I would try and clear some things up.
