Customer Ratings & Reviews

These batteries are such a lifesaver! The batteries that were used before would die while in use, causing a disturbance. These hold their charge through the entire time they are being used!

I was looking for a rechargeable 9 volts battery, it works very well. No need to recharge it for more than a week of daily use.

Got tired of constantly having to buy 9v batteries for my fire detectors so it is nice that I can quickly charge it and it lasts for a long time.

used this as a replacement for backup for my Rainbird Sprinkler system. Was not sure it was going to work but after a recent power outage everything worked fine and I am set for another 5 years.

This is either my 2nd or 3rd purchase of the Energizer - Recharge Universal Rechargeable 9V Battery. I continue to purchase product because it's fairly reliable and is sold for a fair price

Bought these batteries to swap out the ones in my paintball gun. Last as long if not longer than your standard batteries and they are recharchable so I don't have to buy new batteries every week.

Great value for the money! Saves a lot - when you recharge if you use it in any electronic devices constantly

Works fine and fits the need I had. Fair price for the right product

Great battery, have not charged yet since initial use, lasts longer than regular rayovac battery in wireless microphones in my opinion.

Seems to hold charge longer than the generics. Works as expected.

I used these batteries at church. They makes the job much easier. We’ve saved hundreds of dollars instead of using regular batteries.

Great batteries. Last long and efficient. Good buy

Batteries working well. Lasting well with no problems.

I got tired of buying batteries over and over again, so the rechargeable ones are a life saver. They cost a little more at first but in the long run, it's worth it.

This 9V battery is rechargable and highly recommended! The price is right and the battery is reliable.

I use this battery in a tool at our automotive shop. It seems to hold a charge pretty good and has paid for itself.

This battery is currently in use with others of a different manufacturer. It appears at this time to be outlasting the others in time between charges.

This is one of the best batteries I seen for the 9 v rechargeable ones having used alkaline for a long time.

I bought these batteries because I was sick of spending money on batteries so I bought these batteries so I can just recharge them.

This product lasts longer when charged. I use it for my guitar.
