Watson 9V 250mAh Battery Reviews
Great!

I’m a big fan of rechargeable battery because it helps reduce waste compared to regular 9V batteries, plus it eliminates the risk of leaking—something that's often a concern with non-rechargeable batteries. To put it to the test, I used the Watson battery with a Polsen PMA-2B Stereo Personal In-Ear Monitor Amplifier (also available on BH, if you need it). The manual states that a 9V battery should power this unit for about 9 hours. The Watson battery lasted almost 8 hours, which is still very impressive and more than sufficient for most uses. That said, I haven’t tried a regular alkaline 9V battery in the unit, so it’s possible that the unit might consume more power than what was originally tested in a lab. When charging the Watson batteries with the newly released Watson USBC charger, I was happy to see that they didn’t get hot, which is a nice safety feature, insuring longevity in the cells. I personally avoid buying regular 9V batteries due to the waste factor, and for power-hungry devices like this, I find that these Watson rechargeable batteries perform really well. [I have received this product in exchange for my honest review].
Excellent battery

I use these 9V batteries for electronics projects with older ICs and transistors which require 9V. A previous set of these batteries lasted several years, recharging them hundreds of times, saving money and reducing electronics waste. While 9V power supplies are abundant, a stable 9V battery source is often the best since not all 9 V power supplies are of the same quality in terms of noise and stability.

How do you charge this battery? Does it come with a 9V charger?
No, it doesn't.
I have a great charger from Energizer that charges AA, AAA, C, D, and 9V batteries that i use for it.

This is NiMH and described as 9V. NiMH is 1.2V per cell nominally, so with 8 cells would be 9.6V nominal. With 7 it would be 8.4. (Both of these voltages are supported by my Maha charger.) How many cells does this have?
This battery has 8 cells.

question for B&H staff: is this able to power Rode NT3 mic (BH #RONT3)?
The RODE NT3 3/4" Cardioid Condenser Microphone use 9V batteries, therefore the Watson 9V Rechargeable NiMH Battery (250mAh) will be compatible with this microphone.
