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!

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.

I need to get these batteries for a teeth, whitener that I have, and i'm surprised that they even carried them, because I couldn't find them anywhere else period they take two batteries, and every time I open the back of the machine one of the batteries would pop out and I would lose it so I went and I bought a four pack at best.Buy and I haven't had a problem since.

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.

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.

I think for the price should be cheaper for only two in the pack, but if you need these batteries its well worth the price to keep you on your remote jurney or that old watch running.
