Customer Ratings & Reviews

Found these batteries here at the lowest price around. They were in stock and available for same day pickup. Great batteries for my key fob.

They work well and last. They are batteries that work they are expected to. They fit the item I was buying them for.

Wow, a request from Best Buy to review a Li-MnO2 battery... The C (Li) R (round) 2025 (20 mm diameter, 2.5 mm height) 3V (volts) battery has functioned exceptionally well during the two week period following the demise of its predecessor. It has neither suffered from the deleterious effects of rapid-discharge nor detonated. Li (lithium) metal (or an intercalation compound--Li is "captured" between the basal planes of graphite "LiC8") = anode (current enters, e^-1 leaves) MnO2 (manganese (IV) oxide) = cathode (e^-1 enters, current leaves) ***This is not to be confused with Thunderdome, i.e., two men enter, one man leave, even though many electrons flow prior to hearing the clap of thunder*** The Li cell is filled with an organic (Li metal reacts readily with water) solvent that: 1) does not react with Li metal (Li metal also readily reacts with, for example, carboxylic acids and alcohols: such a reaction in a sealed system would produce very energetic catastrophic failures as a result of a combination of pressure and the reactivity of H2 with O2), and, 2) allows for the dissolution of LiClO4 (lithium perchlorate). Its redox chem is rather straightforward in which; lithium is oxidized (0 to +1) and manganese is reduced (IV to III). Li <---> Li^+1 + e^-1 MnO2 + Li^+1 + e^-1 <--> LiMnO2 ------------------------------------------------- Li + MnO2 <--> LiMnO2 Oh, I only bought a four (4) pack because single (1) packs were not in stock. Thanks Best Buy! Now I have three (3) spare Li-MnO2 CR2025 3V batteries.

I got these batteries for my car remote entry module and has worked reliably since. previously the remote would occasionally fail to unlock, but since it worked most of the time I thought the battery was good. not good enough though. if you have this problem try a new battery.

My go to battery with long life, reliability and competitive price.

Long lasting batteries at a good price. They did the job that they are made for.

Use for the TV remote. Handy that this is a 4 pack as you never know when the TV remote is low. Price is affordable.

Reasonably priced, work as advertised. Great Value.

It's pretty straightforward--these are good quality batteries from a known brand. You get what you pay for here.

Very high quality works well for Casio watches. Great value.

Just what I was looking for. Great price. Long lasting would highly recommend.

Excellent quality,reliability is best in the market. I can always depend on Energizer yhat have been powering my cars for years and will continue in future generations.

My car remote battery died. These were recommended and they withstood the test of time for a couple of months now. The only knock against them would be the packaging. Not sure why they have to be in such a package that is so hard to get them out.

These are very good batteries and needed for trusting in long use

Batteries were a great value, and high quality! Needed them for a thermometer I keep in my house, but it was hard for me to find the batteries elsewhere...As soon as I got this pack I popped one into the thermometer and it came back to life. I have a feeling these new batteries will last a while!

Had some old keyfobs for my car that stopped working and realized they needed new CR2025 batteries, and these were the only ones available at Bestbuy. Popped them in and the keyfobs were good as new again, and I fully expect them to last a long time given Energizer's reputation as a trustworthy battery brand.

High quality and dependable product with reasonable price. Last longer than most other products such as Duracell and Maxwell

great name brand product easy to use and last a very long time

I love the fact it comes in a pack that save me years of replacement and saving money.
