Customer Ratings & Reviews

These batteries last awhile and then charge very quickly.

These batteries I live by. I use the 9v for my metal detector and they've never left me hanging. They last multiple days before I need to recharge them, and overall the batteries can last for years with proper care.

I love Energizer Rechargeable Batteries. Buy them once, and then always have them on hand for your smoke detectors, etc. They are a great value. And, Best Buy is one of the few places that keeps them in stock.

This was one of the few purchases ive made that continues to save me money. When you consider the costs of disposable 9 volts how could one consider not buying one of these.

If you use these batteries a lot, you will save quite a bit of money. If you don't use/change them very frequently, then traditional batteries may be a better option.

the battery is great for my baseball radio at the game

this battery is a great value especially on clearance can't go wrong and you could always trust Energizer

9 volt rechargeable battery seem to hold a charge longer than any of the regular batteries I have had in my guitar. The time it takes to recharge is fairly quick.

I use this batteries for my guitar every weekend and had these batteries for a while and have had no problems, I would buy these again when needed and can say they are great!

Love the idea of rechargeable batteries. They work great and other rechargeable purchases have lasted me quite some time!

The battery charges quickly and lasts for very long time

i use a microphone--it demands a 9 volt battery--these batteries last about 2 years lots cheaper than replacing a 9 volt battery after 2 uses

Great rechargeable battery. Last a long time. Good price.

Holds a charge for longer than I thought it would, which is nice because I use it for a couple hours over a period of several times a day.

each and every time it is charged, it works for the same period. So, it retains and discharges charge at the same rate for last 2 months.

rechargeable batteries are getting better all of the time with technology, these batteries work better than expected with a longer life

Must buy it’s really use full. I got mines on a special.

This is the best way to save on battery costs. I go through an entire charge each week, so these rechargeables come in handy!

This is the only brand I purchase anymore the others just don't seem to last or recharge as well.

Works perfectly fine for the wireless mics we use them in. Last the whole time as well, which is about 2 hours
