Customer Ratings & Reviews

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!

Excellent product last a long time happy about this purchase

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.

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

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

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

Needed new batteries for my car's FOB and was able to order online from Best Buy and received them in 2 days. The price was good and I was able to use my Best Buy Reward Points for the purchase.

These batteries last a very long time, definitely impressed

Pretty good batteries, we use them for key fobs and garage door openers.

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.

Works great for my car key. Good quality batteries. They last a long time.

Worked well and took care of the needs. If you need 2025 batteries, these work well.

These batteries were purchased for my key fobs and were not only charged ABOVE 3V but also were LESS EXPENSIVE than the average battery from other brands, which was not expected as it is a name brand.

Energizer batteries are always our go to. They lasts long and never had any issue.

Great long life battery for remote. Quality item, fair price. Used curbside pickup that went extremely well at Stillwater store.

Great price for multiple batteries! So glad I found these in stock!

Works great. Long battery life and easy to use. Good price.
