I would definitely purchase them again.

These 9V lithium batteries (1200mAh) have been a great upgrade compared to standard alkaline batteries. I purchased them primarily for my smoke detectors, and I immediately noticed the difference in performance and reliability. The 10-year shelf life is a big advantage, especially for emergency devices like smoke alarms. It gives peace of mind knowing the batteries won't lose charge sitting in storage. Installation was simple, and they fit perfectly without any connection issues. What I appreciate most is the long-lasting power. Unlike regular 9V batteries that seem to drain quickly, these lithium batteries maintain consistent voltage over time. I've also tested them in a laser infrared thermometer and a multimeter, and both devices performed accurately without fluctuation. The packaging was secure, and the batteries arrived fresh and ready to use. For safety equipment and professional tools, reliability matters — and these deliver. They may cost slightly more than standard batteries, but the longer lifespan and dependable performance make them well worth it.

Good quality, non-rechargeable lithium batteries

These 9V batteries worked exactly as expected and arrived well packaged. I used them in smoke detectors and a few household devices, and they powered everything on right away. Shelf life seems good, with no leak or dead batteries out of the box. They provide study performance for everyday, low drain electronics. For the quantity and price, this pack is a great value. I gladly buy these again to have on hand for use around the house.

I bought the Enegitech 9V Lithium Batteries for my smoke detectors and a couple of small devices around the house, and they've been excellent so far. The 1200mAh power capacity is impressive, and the batteries stay strong without draining quickly like some cheaper brands I've tried. I really like that they have a 10-year shelf life, which makes them perfect to keep on hand for emergencies or backup replacements. They're lightweight, fit perfectly in all my devices, and provide consistent power. I've used them in a smoke detector, a multimeter, and a handheld thermometer, and they've worked flawlessly in each one. For a 4-pack, the value is great—especially considering they're lithium and not standard alkaline. If you need dependable 9V batteries for safety devices or tools, these are definitely worth purchasing.
