Do batteries work better in the cold?
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.
One of the common laws of chemistry is that reactions generally speed up when they get warm and slow down when they get cold. Such is the life of a battery. The problem is not with storing batteries in the cold, but rather trying to use them when they are cold.
- 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.
- But if a car battery is discharged because of damage to cells, poor connections or a charging system that isn't doing its job, the battery could start freezing at the same temperature as water at 32 degrees Fahrenheit. "A 100 percent fully charged battery will not freeze until approximately minus 76 degrees Fahrenheit.
- When the active material in the plates can no longer sustain a discharge current, a battery "dies". Normally a car (or starting) battery "ages" as the active positive plate material sheds (or flakes off) due to the normal expansion and contraction that occurs during the discharge and charge cycles.
In general, alkaline batteries perform very poorly in cold weather. As alkaline batteries are engineered with a water-based electrolyte, cold near-freezing point temperatures can lead to reduced ion mobility which slows down the chemical reactions that provide electrical battery power.
- 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.
- The outer cases of VHS, Betamax and audio cassette tapes are indeed plastic, and at least theoretically recyclable. But you can't just chuck the whole thing into a recycling bin. The inner tape is made of a phthalate-laden form of the plastic polyethylene, often sold under the trade name Mylar, which is not recyclable.
- Click the "use Windows Defender" link in the Settings app to access Windows Defender, and then click over to the History tab. Click "View details" to view detected malware. You can see the name of the malware and when it was found and quarantined.
Be aware that freezing temperatures can do a number on your car battery. During cold temperatures starting an engine can take up to twice as much current as needed under normal conditions. It is advisable to have your battery tested, as well as your starting and charging systems prior to the deep cold of winter.
- First of all, adding larger fuel injectors WILL NOT CREATE EXTRA HORSE POWER! There is a common misconception that the larger the fuel injector, the more power they create. Fuel injectors do not create horsepower, they support horsepower. The larger the flow rate, the more horsepower they are able to support.
- Larger injectors will not give you more HP. Going to a larger fuel injector is needed if you greatly increase the amount of air your motor is pulling into it. Ask your tuner what Duty cycle your injectors are running at Wide Open Throttle. Duty cycle is basically how hard your injectors are working.
- Clean the fuel system from the gas tank by adding a premium formula fuel system cleaner. Fuel injector cleaning or carburetor cleaning, intake valves, and combustion chambers with fuel system cleaner. Use fuel system cleaner to purge water from the fuel system. Lubricate valves, cylinders, injectors, and rings.
