Most people are familiar with cold-induced battery issues. More than one worker has had to call in on a winter day because the car won't start. But in reality, heat is even worse for a truck's battery. Extreme heat causes water to evaporate from the battery's electrolyte.
What kind of batteries work best in the cold?
In general, alkaline batteries perform very poorly in cold weather. Panasonic's CR123A lithium batteries (PDF) have an operating temperature range of -40° to + 70°C (-40° to 158°F), while Energizer's Ultimate Lithium L91 AA batteries (PDF) have a similar operating temperature range of -40° to 60°C (-40° to 140°F).
Batteries are affected by humidity and temperature. If they are too hot or cold, they will exhibit behavior that is incongruent to their normal specifications. Extreme heat can lead to battery corrosion that shortens the average car battery life.
As Duracell's website says: “Alkaline batteries can be safely disposed of with normal household waste.” Energizer confirms that regular batteries are fine to toss in the trash, but says rechargeable batteries should be recycled according to US federal guidelines.
If your control still works with a nw battery then this is probably NOT what happened. It is EXTREMELY unusual for an AAA cell to "explode" in use. If a non rechargeable battery is charged it MAY explode. This would be rare and it is unlikely your remote allowed charging.
Is the summer heat draining your car battery? OKLAHOMA CITY – Summer heat can drain your car battery in record time. “Any extreme temperature, cold or hot, can be really detrimental to a car's charging system, particularly the battery,” said Jeff Beck, of Beck's Auto.
Cold weather is especially hard on car batteries. According to AAA's Automotive Research Center, at 0°F, a car's battery loses about 60 percent of its strength and at 32°F it loses 35 percent. During cold temperatures starting an engine can take up to twice as much current as needed under normal conditions.
The more light the object absorbs, the more heat absorbed since light is energy. If you consider it a color, black absorbs the most heat. A black object absorbs all wavelengths of light and reflects none. Objects that are white, on the other hand, reflect all wavelengths of light and therefore absorb the least heat.
“When most motorists think of dead batteries that cause starting failure, they think of severe winter weather, but summer heat is the real culprit,” says Rich White, executive director of the Car Care Council. “Many battery problems start long before the temperatures drop. Heat, more than cold, shortens battery life.”
Batteries are a function of chemical reactions. In cold weather the chemicals can not react as fast as in warm. In fact keeping a battery cold will extend the life of the battery, by slowing the chemical discharge. A cold battery may still be good but will not have the same the power as a warm one.
A: Cold weather is often fingered as the culprit when car batteries die, but actually warm temperatures do the most damage to them. A cold battery has reduced cranking power, and cold temperatures thicken motor oil, making it harder to turn the engine over.
If only blue light is shone onto a red shirt, the shirt would appear black, because the blue would be absorbed and there would be no red light to be reflected. White objects appear white because they reflect all colours. Black objects absorb all colours so no light is reflected.
When all that body heat hits the white clothing covering it, it gets reflected right back towards the body. When we wear white, we cook ourselves. The best color to keep cool in the heat, it turns out, is to wear black. Black absorbs everything coming in from the sun, sure.
When choosing clothing to protect against the sun's harmful ultraviolet rays, people should consider blue or red colors rather than yellow. A new study shows that these darker colors, when applied to cotton fabrics, tend to have better UV absorption.
When we wear white, we cook ourselves. The best color to keep cool in the heat, it turns out, is to wear black. Black absorbs everything coming in from the sun, sure. But black also absorbs energy from the body instead of reflecting it back.
White, silver, and other light colors are coolest, reflecting about 60 percent of sunlight but there are dark "cool" colors that can also stay cooler than traditional dark colors.
When a color (colored fabric) absorbs light, it turns the light into thermal energy (heat). The more light a color absorbs, the more thermal energy it produces. Black fabric absorbs all colors of light and is therefore warmer than white fabric which reflects all colors.
When a light ray (of any color) hits a mirror, it reflects as another light ray. But for a white nonreflective surface, it is scattered in all directions. From the perception side, a eye gathers incoming light rays to form image on the retina.
The outer layer of fabric does get hotter because the black color absorbs more heat. And that heat doesn't get transmitted to the skin because of the thick fabric. But thin black clothing transmits that heat to the skin, making a person hotter.
A black object, like a t-shirt, looks black because it absorbs all the wavelengths in white light and reflects none. Instead, as the light is absorbed, it gets converted to other forms of energy, usually heat, and then emitted by the shirt.
