Winter and Phone Batteries

Very low temperatures can reduce your battery to ½ or less of your normal use time. Keep your phone warm to keep your battery level up. If it gets cold and battery charge goes down, making the phone warm again will not bring up the charge level.

Battery Cost

Here is the cost and value of various batteries.

Battery Facts

A major site compared 40 batteries using fast drain and slow drain technology. Its findings mimicked other findings from a number of other tests. 

The resulting data yielded some interesting results. First, highest price is not highest value, and second, zinc batteries, although usually the cheapest are poor value as they drain faster than alkaline and lithium batteries. Brand name has no relation to quality, but are usually higher priced.

Bottom line is that buying the cheapest non-brand-name alkaline battery is almost always the best value. Lithium batteries last the longest, but are almost always not the cheapest. In the tests, Ikea alkaline batteries blew away the competition for best value.

Think about how often you change batteries for every day use items, such as TV remote, computer mouse, clock, smoke detectors, flashlights, etc., it is usually once every year or two, or even longer.

My advice - if you need long stable battery life (such as for a good camera), pay more and buy lithium. If you want the best value and do not mind changing batteries a bit more often, buy the cheapest alkaline you can find.
