These are great rechargeables for holding a charge and powering your 9v devices. Great way to save money on 9v's each year when replacing smoke alarm batteries, etc. However the problem I've had is when I go to remove the batteries to recharge them. So far out of 6 batteries, I've had 2 which have the positive end just pop off. (it doesn't reattach). I'm currently in the process of getting them replaced with Tenergy, but do not use these for life saving devices, or if you do such as me with smoke alarms be very careful when you remove them from a device. We'll see how good the rest are when I go to remove them a year from now. :)

Tenergy customer support will not replace items ordered through amazon. So once past your 30 day return period your out of luck with these batteries. So be very careful when unplugging them when they come due for their first 6 month recharge, etc. Else you might as well plan on having some fall apart. I would have hoped Tenergy CS would have handled it better.

I'm sure in my 57 years that I've used hundreds of nine volt batteries--both single use alkaline and rechargeables. This Tenergy 200 mAh battery is the first one that I've ever had that the positive terminal post snapped off on the very first use! And that was from taking it out of the charger!
I can't review the battery any further. I can not put it in any device since it has no terminal. I'll stick with my previous brand, Maha Powerex, which have given me no trouble in the three years I have been using them.

I have a clock radio that uses a 9v battery for backup in case of power failures. When the power goes out the clock display shuts off to save power but the battery allows it to still keep time and if your alarm is set it will go off as usual. The clock has a low-battery warning light to let you know when to replace (or in my case recharge) the battery.

I was using one of the first old style NiMH 9v batteries that was not low self-discharge that had a 150mah capacity and I think around 7.2v output. When it was fully charged and I put it into the clock radio it would take literally 3 or 4 seconds for the low battery light to come on. Obviously the battery didn't have a voltage above the threshold of the warning light so it came on immediately and stayed on. The battery did have enough power to run the clock if we lost power which was good, but it was annoying that I didn't have any way to know when the battery was drained. I found out through trial and error that the battery would only last about two or three months due to it self-discharging over that time. And that was without any power outages.

So I went with this new low self-discharge 9V battery to see what would happen and couldn't be happier. It has a higher voltage so now the low battery light stays off (at least so far). I ordered these along with the Tenergy TN141 2 Bay 9V Smart Charger for NiMH 9V Rechargeable Batteries and gave the battery a quick charge to top it off before use. It has been about a month now and I just picked up the

Most 9V rechargeable batteries I've bought in years past were actually rated 8.25V and only 150 mAh (Radio Shack). I personally won't buy anything but pre-charged rechargeable batteries anymore. They hold their charge respectably for a change and I can actually use them in my flashlights. I've had great results from other brands of this technology and these are no exception. These arrived already holding a full 9V charge and are rated at 200 mAh. (Straight off the charger from this manufacturer (Tenergy V3969A1) I've seen as high as 9.4 volts.) I see this as a great benefit since it will help my wireless microphones perform to full specifications before loosing performance based on dropping voltage (Condenser microphones). I want about Ten hours of run time which these appear to be able to handle (I have yet to push mine that long to know for sure. Only 8 hours but still had over 8.5V under load). I'm glad I purchased these on sale (2 pack for $6.99) A great value at that price! I hope these will be available in the future when I need some more!

I bought these batteries for my Taylor acoustic guitar. Unfortunately, they won't fit in the battery holder since they are slightly larger than standard 9v batteries. They may be useful for other items, but they won't work in my guitar.

5/2014: Here's a video from Taylor guitar on modifying your 9v battery cradle to accept larger batteries; I have not tried this yet. Taylor does not recommend rechargeable batteries, but say to do this if you want to try them. Also, I have read that the new lithium polymer rechargeables may be the way to go for rechargeable 9v batteries in guitars. Again, haven't personally tried them, just info. Just be sure to use the correct charger with them.

2 of them broke after a few weeks. The plus contact just came off.

I had them lying on my desk and when I finally had time to call the company, they told me they only had a 90 warranty / replacement policy.

I wanted to outfit all my irrigation controllers with those, but since they do not warrant their product and she also said "it's ok", when I told her I could not buy her product in the future due to them not taking responsibility for their products, I would buy these with caution...
