Weather stations that can be used by people at home are quite useful weather instruments to monitor one’s immediate environment. These tools have the ability to provide information that the weather man can’t. There are many different types of weather instruments that offer excellent utility and accurate information for a range of activities, including sports, research, professional photography, adventure travel, and agriculture etc. A weather station at your house can be quite useful especially on the months of fall and winter, during which time the weather can be quite unpredictable. Weather during summer is pretty much predictable, but winter months especially in colder regions of the United States of America and Canada can be quite dangerous.
Unfortunately, even if you buy one of the best brands of home weather stations, it’s the batteries that often pose a problem. The colder the weather, the worse their performance. When compared with car batteries, that give specific warnings regarding battery performance during various seasons, batteries used in these weather instruments are conspicuous due to lack of this information. Since batteries form an important part of the station system, it’s important to not just be able to choose the right battery but also understand the difference between the different types.
Alkaline Batteries: These batteries are good for weather station sensor located outside your home during mild summers to cold winters. However, as it gets colder, below freezing point, the chemicals in the battery start to have a problem and become weak and may stop working altogether. However, new alkaline batteries may still work up to 0 degree Celsius. If your battery is weak, bring it indoors to warm it up and use them again.
NiMh Rechargeable Batteries: If you stay in a really cold region where temperatures during winter months, often fall to below 0 degrees, its best to buy NiMh rechargeable batteries. These batteries work up to -10 degree C levels, however, you will have to recharge them on a more frequent basis to keep your weather station working.
Lithium AA Batteries: A new entrant in the market, these Lithium AA size batteries are excellent for cold weather. They work even in temperatures as low as -30 degrees. However, unlike NiMh cells, these batteries can’t be recharged and must not be used in the NiMh AA recharger.
In case you have a portable weather station that works with remote sensors and has a LCD display, it is possible that even when you use Li batteries the display tends to freeze below 0 degree. The reason for this is because LCDs are incapable of operation in very cold conditions. However, keep the weather meter inside exposing it to outside environment only when you need to check the weather and just trust the device! In any case, weather stations display the data on the screen indoors and will indicate a problem, if it does exist.

Cell Phone Battery

Cell phone batteries and cell phone chargers
Cell phones have changed the way people live their lives. They can stay in touch and get things done without missing a beat. The amount of time people use of their cell phones continues to increase. As people are using cell phones as a business and home phone, it is necessary that they can withstand all the use. Without very powerful batteries, cell phones would not last very long against this increasing rate. If you own a cell phone, which you probably do, you can already understand the importance of a powerful battery and an effective charger. People don’t have time to wait for a battery to charge. That’s why cell phone batteries and cell phone chargers have come a long way to increase life and charging time.
Every so often, a new cell phone battery must be purchased. This usually happens when the cell phone battery life has been drained due to improper charging. However, new lithium ion batteries do not typically have this problem.
When purchasing an additional cell phone battery, the battery must be selected from the manufacturer, as the battery types differ greatly by brand and cell phone model. They are essentially the same type of battery, but design and technology of different cell phones require differently designed and developed batteries. Some batteries have more power if the cell phone runs more applications and programs than simply calling and storing numbers.
Cell phone charges are also different depending on brand and model. There are usually many options for cell phone chargers. Standard cell phone chargers are plug in, inexpensive, but do not charge very rapidly. Travel chargers that plug into a vehicles AC adapter are slightly more expensive, but charge cell phones very rapidly and are extremely convenient on the go. Desktop chargers are useful if you have an extra cell phone battery. They can charge the cell phone and the additional battery at the same time. That way you are always guaranteed a fully charged battery.
Cell phone batteries and chargers are constantly being developed to have longer life and be more powerful. Batteries will soon be introduced that charge to full capacity in minutes and last ten times longer than current batteries. As with most technology, it can change in the blink of an eye, but usually for the better.
