Customer Ratings & Reviews

Excellent product last a long time happy about this purchase

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.

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.

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

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

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

Very reliable batteries with a long shelf life and usage life

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

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

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.

Put these in my car key. Usually last at least a year, and that works for me!

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

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

Works great on my key fob and battery last long. Great price , will definitely purchase again.

Like buying these batteries in bulk? I like having these products delivered to our front door.

Very economic choices for the the many different uses it has, i used on my cars key fob and it gives excellent life vs price

Grateat product and people working there. I gt helped the whole trip

These batteries work the best for my keyless entry and starting a vehicle. Laughs about six months. Before you have to change batteries. Great value for the money

Works ok. Only writing this for a chance of a 400 dollar goft card
