What voltage do these hold? I know many are 8.4v and lower. I need 9v or higher. Thanks

This battery is rated for actual 9V *please note, this is non-rechargeable. NiMH 9V (rechargeable) or other rechargeable can be rated 8.4V or less.

I have a 9v battery 6clr61. the battery being shown just says 9v. how do i know if this will work in my electronic device?

YES, this 9V Lithium battery can be used to replace your previous 9V Alkaline (6LR61) batteries without issue.

Smoke Detector Life Span.... not so much a question for the battery but for your old devices...?

Smoke detector life is 8 to 10 years

can I use these batteries instead of the regular 9volt in my power recliner that has a battery backup?

While we are not fully familiar with that specific model, we can offer some quick suggestions to determine what type(s) of battery pack is compatible with your model by: 1) Checking with the manufacturer or manual. 2) Check against your original (old) battery that came with the device. The battery information that users would need to look for will be to match chemistry, voltage, and battery dimension. If this matches then it will generally work. Additionally, we understand that some customers may want to upgrade their original battery to a Lithium battery - before doing so we'd like to caution and advise users to first check with the device manufacturer if it can support Lithium batteries, otherwise you may risk damaging the device. If you are still unsure, and have some minimal information, or even a photo of the original (old) battery, please reach out to our Tenergy Support team, and we'll try our best to assist.
