"We used all the last box at our old home. And when we moved, I knew what batteries to get for the smoke detector."
"These 9V lithium's are my go to 9V for everything and they last much longer than any other battery hands down. Battery junction always has fresh ample stock whenever I need them!"
"Successfully used these to get 10 year life in smoke detectors. Tried a different brand and didn't make 5 years. Won't make that mistake again. Order 2 packs for both houses. Battery Junction had good prices and service."
"I use these in my fire alarms and they last for years."
"We use this in our Wireless microphones at church and have found them to be great at holding their power over multiple weeks. We use Shure Wireless OTE mics and have been very happy."
"These last considerably longer it seems then other brands. I bought a 10 pack and they have lasted considerably longer than 12 packs of other brands I have bought."
"I order these batteries in large quantities for my office quite frequently and have had no problems or issues with the product itself or the delivery. The batteries work great and it’s a great value for ordering higher quantities. I only go through this website now for my battery and other purchases."
"After one of our detectors (we have 8) started chirping at 1:00 AM, all I could do was cover my head with a pillow and wait for morning. We also have 10 foot ceilings so I was not about to start digging out the ladder and trying to locate the offending unit at that hour of the morning. After my morning coffee I found the problem unit, replaced the battery and decided never again (or a least for a long time) so I bought this 10 pack and installed in each unit. On some of the units it was a bit snug but all went in and I can relax for (I hope) 10 years or so. Good product at a great price."
"just started using em, good price will see in 6 to 12 months use lithium in test eq vom meters ect that may not get used alot"
"Recently ordered batteries for all our rental properties so not sure about longevity. Price is good, shipping is slow."
