Is the actual voltage of these a full 9 volts or 8.4?

I just finished recharging one of these batteries and my VOM says it has 8.23v.

they aren't full 9 volts. all of the devices i use them in work fine on their voltage. i just checked 1 of my spares that has ben sitting since feb and after 6 months it has 8.23 volts on a volt meter and on a battery checker it's meter is is as high in green as it goes. For us these last longer than any others we used rechargeable or none that's why we had one that's ben sitting 6 months

Yes, this is correct. When fully charged the batteries measure 8.4 V. When the batteries discharge halfway their voltage also gradually drops to 7.2 V. At empty, these batteries are about 6 V. To charge them back to full, you need to bring their voltage back to 8.4 V, hence the 8.4 V charger.

Why would you convert 12v to 9v? The lights are produced to operate on 12v. If you are asking if they will operate on a little 9v battery as from a smoke alarm, poorly.... blink a few times and lights out, can test a minute to see if they work ok? If using a brick battery with a few amps or so, they will work ok....or at least the strips have for me, but poorly compared to giving the full 12v+ they are made for. Best I can offer from the question is give the strips the 12v+, and at least 2a per strip needed to work as expected.

6.8 volt. Do not accept or buy any other brand for replacement. ONLY use Sony. This is an excellent battery.

They're really 6 Ohms. Kinda ambidextrous. Since it is equally in between 4 and 8, it can be used for either application.

Not sure because there is a circuit board attached to them, but the plug is 110V.

The package says 1.2 volts, but mine are at 1.31 at a 90% charge. I just checked them with a digital multimeter.

They require DC voltage. They are rated for 12V. They come pre-wired for connection to an AC/DC converter. I wired them to a 9V battery and they work fine.

They are 36V. I have 4 batteries operating on a couple of tools so there are always charged spares.

These are multi voltage units. Do you have the correct voltage setting? Sounds like you don't.

The wattage listing on these is not correct at all. They are ok for replacing factory speakers, but if you put 800 to them they would pop in a second.

I use these with 3 volts (2 AAA batteries) and a 150 ohm resistor. To use 9 volts you need to use a ~450 ohm resistor , but, yes, they will work fine with a 9v battery.

they are small hearing aid looking battery. Not sure of the voltage. It uses 3 batteries at the same time

My ones are 120V, ordered from USA. They're pretty good, but are not bivolt. A converter should solve your problem.

They were 2015, not sure about the voltage, fit size 10 hearing aid which is a miniature size. I send them overseas otherwise I could check the box for you.

It have 8 individual 9v port plus one 18v output, one strip to change polarity if needed, not sure of output amperage

I belive they are a 8 ohm. But I wouldn't buy them the poorly constructed. You have an issue where the bracket and speaker are bolted by the knob. The internal nut that is glued on the in side breaks loose when you tighten the knob and the only way to fix it is to pull the screen offand reatreattached the screw with stronger glue. My buddy bought a pair also a week later and had same issue.
