Battery D-Size Alkaline Philips

Alkaline batteries are disposable batteries with zinc and manganese dioxide as electrodes. The alkaline electrolyte used is either potassium or sodium hydroxide. These batteries have a steady voltage offering better energy density and leakage resistance than carbon zinc batteries.

The alkaline batteries come in various sizes ranging from AAA to AA, C, D, 9 V and others. AAA and AA are suited for low-drain applications whereas AA is used for high-drain applications. C, D and 9 V are suited for high-drain applications as well. Others include micro alkaline button cells, coin cells, AAA and the like. AA is the most widely used alkaline battery cell size, while the AAA size is the fastest growing. Size C, D and 9 V are used for specific applications which have steady demand. However, other sizes such as micro alkaline coin cells and button cells are used in few industrial and medical applications.

All of these configurations are likely to be used on gadgets immediately after purchase, which make them suitable for use even during emergency situations. Additionally, long shelf life offered by these batteries (ranging from three to four years) makes them suitable for storage.

Alkaline batteries are environment-friendly, which are anticipated to be disposed as trash and do not require active collection and recycling. Moreover, those made currently by almost all the major manufactures are mercury-free and hence, do not pose any environmental pollution or hazard on disposal.
