Product InformationCoin Manganese Dioxide Lithium Batteries are being used in a broad range of applications, from quarts watches and clocks, a backup power sources for memories requiring long-term reliability over 10 years to IoT equipment, and car keyless entry systems.Lithium metal, used for the anode in Coin Manganese Dioxide Lithium Batteries, has the largest electric capacity per unit weight (3.86 Ah/g) among all the materials usable for the anode. Thus, batteries with a high energy density can be produced.Also, by using different active materials for the cathode, batteries with diverse characteristics can be made. Sony has commercialized the Coin Manganese Dioxide Lithium Batteries, which uses manganese dioxide for the active cathode material for superior stability.Lightweight, High Voltage and High Energy DensityThe battery voltage is 3V, almost double that of normal alkaline or manganese batteries. This means that the number of batteries required for equipment can be halved for maximum space saving and weight reduction.Excellent Discharge CharacteristicsVoltage characteristics remain stable even for a long period of discharge, greatly improving the reliability of equipment that uses the battery. Such equipment is also maintenance-free (battery replacement is seldom required).Outstanding Temperature CharacteristicsSony's original organic electrolyte provides superb characteristics over a wide range of temperature from low to high. (-30 to +70 degrees C)Excellent Leakage ResistanceThe newly developed battery construction and electrolyte ensure maximum leakage resistance over a long span of time.Excellent Long-Term ReliabilityCarefully selected active materials are used for the active material as well as for the electrolyte. These materials are sealed by Sony's innovative technology to minimize battery self-discharge. The annual self-discharge rate at room temperature and normal humidity is less than 1% of the nominal capacity.-----Principles of Lithium Manganese Dioxide BatterySpecially processed manganese dioxide (MnO2) is used for the active cathode material, and high-voltage, high-activity lithium metal for the active anode material. The electrolyte is lithium salt molten into an organic solution to ensure easy transmission of high voltage and high energy to the exterior.With open circuit voltage of approx. 3V, the battery voltage is extremely stable and impedance remains low and stable during discharge.Storage at 60C for 120 days is the equivalent of storage at room temperature for 6 years.Excellent long-term storage reliability.After storage, discharge voltage/discharge time show little decrease and are stable.

The battery was exactly what I ordered, and the delivery was early.

3 V Battery

walmart.com

The pictures indicate one pack of two as they show 2 side by side.  This is only a pack of 1!
It did arrive a week earlier than stated!

Not as pictured! Arrived quickly

Should have read reviews. I thought it was a 2 pack, but it was 1.

Only 1 battery!!!

I wish I had read the other reviews.  Picture shows 2 batteries.  It is only 1.  Pretty misleading, but I guess I should have known better...

The Picture is Wrong

These batteries didn't even last a couple weeks it was terrible. I've never had batteries last such a little time!

These batteries didn't even last a couple weeks it

Very misleading.  It looks like you get two batteries but you don't you get one. The wording says Battery but the photo shows two.  Frustrating.

Buyer beware there is only 1 battery in each pack

description and picture say two pieces. only one arrived. again Walmart screws up.
