1.Do Alkaline-manganese batteries last longer than carbon batteries?
Yes, often at least twice as long. For continuous discharge applications (such as cassette players, digital cameras) use alkaline-manganese batteries. For discontinuous discharge devices (remote controls, transistor radios, flashlights) zinc carbon may be preferable.
2.Can alkalines be re-charged?
Although some alkalines can be recharged. charging primary batteries is uneconomical and can be a serious safety risk. It is better to purchase rechargeable batteries if one wants to re-use batteries.
3.What are the Primary batteries available in the market? Primary batteries are sometimes called "throw-away" batteries because they will be discarded when they are flat, as they cannot be recharged for reuse. Common types of primary batteries include alkaline, zinc carbon, lithium, silver oxide and zinc air batteries.
4.Do warm and cold temperatures affect batteries? Extreme heat or cold reduces battery performance. Avoid putting battery-powered devices in very warm places. In addition, refrigeration is not necessary or recommended. Store batteries at room temperature in dry environment
