5-Pack Cotchear 12V 27A Alkaline Batteries - Long Lasting 12 Volt 27A/21-23/E23A Replacement Batteries for Key Fobs, Garage Door Openers & Electronic Devices

Leak-proof Technology is Upgraded Again Stainless 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 Discharge The 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 Durable Using 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 Batteries Capacity Manganese 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 Current Alkaline 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. Durability Alkaline 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 Batteries More Durable Long Storage Life The Shell is Not Easy to Corrode Large Current, Suitable for High-power Electrical Appliances High Cost-effective Mercury Free and Pollution-free No added mercury or other harmful substances, healthy and environm entally friendly. Keep away from fire Do not throw the battery in ti fire, do not recharge Keep the battery in a dark, cool and dry place. Do not use different kinds of cell together.
