Gn 5Pcs 12V 27A Alkaline Battery 12 Volt Batteries 21/23 E23A

 Before making any purchase kindly ensure the battery is compatible with your watch/device. Not all watch batteries are the same. You can confirm the model number from your current/previous battery, if it contains any of the model numbers shown below then it will fit.  Thanks for your understanding!
Leak-proof Technology is Upgraded AgainStainless Steel Anti-corrosion Shell, Adding Insulating Anti-leakage Film, Effectively Reducing the Damage to Components Caused by Liquid Leakage Inside the Battery
Safe Structure, Stable DischargeThe built-in spring sheet can effectively prevent the battery cell from being damaged when the battery is sealed, and ensure the good contact of the battery cell and stabilize the output current.
High Quality Stainless Steel Shell, More Secure and DurableUsing anti-corrosion stainless steel, the steel surface is hard and not easy to be damaged; anti-corrosion, anti-deformation, anti-explosion and anti-leakage, providing a longer service life
Features of Alkaline BatteriesCapacityManganese dioxide used as cathode has high purity and density, and the internal parts are smaller in volume, which helps to increase capacity, which is 3 to 5 times more capacity than carbon batteries
Electric CurrentAlkaline batteries have larger capacity can output larger current because the electrode area is increased, and there are more substances that can produce chemical reactions at the same time.
DurabilityAlkaline batteries have extremely high depolarization efficiency, so they can continuously supply large currents, while carbon-zinc batteries must be used intermittently. Alkaline batteries still maintain an output capacity of nearly 1.5V after a period of use
Advantages of Alkaline BatteriesMore DurableLong Storage LifeThe Shell is Not Easy to CorrodeLarge Current, Suitable for High-power Electrical AppliancesHigh Cost-effective

Mercury Free and Pollution-freeNo added mercury or other harmful substances, healthy and environmentally friendly.
Keep away from fireDo not throw the battery in to fire, do not rechargeKeep the battery in a dark, cool and dry place.Do not use different kinds of cell together.Insert the battery in the right direction and avoid short-circuit.
