Customer Ratings & Reviews

[Employee of bestbuy] When my dad’s car key battery died, these Energizer 2025 batteries were a total lifesaver! They were easy to install and worked perfectly right away. It’s great having a 4-pack, so we have extras on hand for the future. Definitely reliable and long-lasting, which is exactly what you want for something like this. Highly recommend for anyone who needs dependable coin batteries!

Full battery capacity with more years expiration date

These batteries are so incredible. I am just speechless. Like I am so humbled by the privilege to own, not one, but TWO. TWO of these technologically super advanced mega power producers. I feel we should replace all the nuclear power plants in the world with just a few of these babies. What a time to be alive. Glory be to God.

Needed replacement batteries for our Samsung 3D glasses. Perfect fit. Also is the same size our kitchen food scale uses. Thank you Best Buy! Totally what we were looking for.

Excellent product last a long time happy about this purchase

These are the Best 2025BP-4 Batteries I have used! Highly recommend

Needed these for some candles we put in our window. They work great.

Needed new batteries for my car fob and these worked out perfectly!

Great for car key battery Hope will ladt long. Will update as i use.

Very reliable batteries with a long shelf life and usage life

Compatible with the liftmaster garage opener. I googled recommended battery sizes for the device which suggested 3V 2032; took a chance and bought these ones since it was the previous battery in the device. My garage key wasn't opening the garage from a distance or up close, even after the button was pushed several times. Changed out the battery and it works like new. Way cheaper to buy batteries than a new garage opener.

These are reliable, strong, and long lasting very happy with my purchase

[Employee of bestbuy] Good batteries. Fit as expected. Performing well. Device's range has improved due to power provided by the batteries.

Battery works great in my key fob! The old battery died and this one was full of energy and allowed me to unlock my car again! Wow, amazing!

Energizer batteries fit as they should and worked well

Works and reliable. Had no problems. Used it for remote control, no issues.

Quality brand, battery last long, just bought it for my keyfab

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.

Good set of batteries, works as it should! Hoping they will last a long time as advertised
