great I put these in my smoke detectors and they last for a long time! May 26, 2012
Just doesn't stop! A couple of weeks ago we lost power for several hours. A friend brought me a battery powered clock radio so that I would have something to listen to, but it was brand new and needed a 9v battery. So I went on the hunt looking for one and finally found one in a toy I hadn't seen in ages. I just knew that Energizer battery would not have any juice. Well was I proven wrong! Not only was the battery in excellent condition, but it had enough power to provide me with music throughout the night. May 25, 2012
This product is dependable Changing batteries in smoke detectors is important to me. I want a battery I can trust to do the work it is intended for. Energizer does the trick! Recommend Highly!!! May 20, 2012

Answer: 
Thanks for your question. Below is the answer from from our technical team.

Capacity = 625 mAh under a 25 mA load to 0.8 volts per cell. There is no direct conversion for mAh to joules. However there is a conversion of watt hours to joules (10,000 joules = 2.7778 watt hours). The watt hours can roughly be calculated by multiplying the amp hour capacity by the average voltage during the discharge.

Answer: 
The battery capacity may be influenced by both temperature and discharge rates during use. However, setting those variances aside for the sake of example, you should multiply the 9 volts times the mAh to establish the milliwatt-hours. The sum will equal watt-seconds or Joules.

Answer: 
Hi Lucy, thank you for this great question, I would be happy to assist you. There is not a maximum current specification for alkaline batteries. The time desired and the minimum voltage required at the high current will impact if the battery will meet the user’s needs. For example, if only a few second pulse is required, the battery can deliver significantly more current than if hours of service is needed. A discharge curve for our 522 9 volt alkaline battery could be around 100 mA for continuous drain. Please feel free to contact us with any additional questions or concerns on this at 1-800-383-7323.

Answer: 
Thank you for this great question, I would be happy to assist you. When it comes to smoke alarms and our Energizer 9v batteries, we normally recommend changing them over every 6 months. Though that is just a recommendation, you can leave it in longer without changing it, as long as you keep an eye on the use by date the battery should last for many years.

Thank you for taking the time to contact Energizer
