Are these batteries actually 9 volts output minimum?

Not quite. The claim is that they will improve after the first few charges. I get anywhere between 8.5 to 8.7 volts on full charge. So far they seem to last just as long as any other brand in my motion detectors.

I have not actually put a meter to them; We use them for wireless microphones in a church setting with no problem.

I've never measured. Li much better than NiCad. Runs wireless microphone very well.

Only if fully charged. Will drop below 9V when weak like other rechargeables. I bought 4 of these Li-ion batteries for our church wireless Shure mics. Firstly they must be charged by Li-ion battery chargers, not the regular Ni-MH chargers. Secondly, 2 out of 4 died on us after less than 2 months of use. Not sure why. On the bright side, the sellers were excellent. They replaced the batteries for us even after 2 months of use.

These batteries are rated at 10 amps. If you plan on going under .5 ohms of resistance these are not for you. Otherwise they are a great cell.

I checked several of the batteries when I received them and they were 1.626 - 1.627 volts.

These are 12 volt 35ah batteries. (Volts x amps = watts) So 12vx35ah = 420 watts max capacity per battery and 840w for the pair. If you want your batteries to last, do not discharge below 50% -- Therefore, with (2) batteries at 420 watts each, there is a usable 420w if you want your batteries to last a reasonable amount of time (500 cycles) - Your application may already have a low voltage limiter which won't let you drain below 11.9-12 volts which is about 50%

Usually this kind of batteries come charged with 40% or less, I think this was the case but I'm not certain

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.

I was pretty sure it took a 9v, I just opened mine to confirm. 9 volt. Take care...

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

If by "minimum charge" you mean you should not use it below 3 volts per cell (total 9volts) then yes. Dropping it below that will shorten the lifespan of the battery. You , of course, could run it completely dead but that would be bad for it. It is a three cell battery which actually charges to 12.6 volts total on most chargers and in use you don't normally go below 3.5v/cell or 10.5 volts total. Was this helpful?

It's a 9 volt battery so when it's fully charged the voltage should be 9 volts.

don. i purchased and received 36 volt batteries. extremely satisfied with their performance. clblanc.

ah they are 10amp 3.7 volts but not sure about the minimum load. It is the same battery that is sold in the vape shops, just cost less here.

I would say no, rechargeable batteries are slightly less voltage. I t would check but not as accurately.

Maybe, but these batteries are falsely labely and have varying outputs, nothing like what is stated. Plus these batteries are not protected and can possibly burst. I should warn you that the charges can catch fire easily too. These are imitation batteries. They should be around 10$ for 1 quality battery.

I do not recommend these batteries. They deliver more than 3.6 volts under load and more than 4.00 in open load. They are unpredictable, they do not hold charge after a few cicles, and if you use two of them like in series, one will hold charge longer than the other. I don't know why they sell them as 3.00 volts. Bad bad :-(

i am not an electrician but with one 9 volt battery at the relay, i would think its somewhat less than that.

I charge them all the time. I'm sure it may take longer than lower output batteries but I have not measured the difference.
