Choosing Batteries For the weather stations for home

Weather instruments, for instance weather stations for home or professional handheld weather meters, are useful tools for monitoring your immediate environment. They might provide information that your particular local weather man (meteorologist) can’t. Aside from the handhelds, which usually are used all year long for professional, sports, and research applications, home weather stations usually are most popular inside fall & cold months of winter when the climate is most active. To be honest, the weather reports is often rather boring over the summer months. But, within the inland northwest issues with weather stations that hamper their performance in the winter months, and the issues be a little more obvious the farther north you are going into the norther U . s . and Canada.

Precisely what is this issue?

Batteries.

The colder it gets, the worse they perform.

Most car batteries (flooded lead acid & deep cycle) offer specifications regarding performance degradation because temperature changes. Unfortunately We’ve yet to view such information furnished by manufacturers for NiMh rechargeable AA batteries and other types. So, I believed I would write this quick article to give you some numbers to recollect…

Alkaline Batteries… Think freezing

You can anticipate these to manage to provide capability your outside weather stations for home sensors into about 30 degrees Fahrenheit (0 Celcius). The chemistry sets out to have problems below this temperature, and unless your batteries are new to angling, you may see weak batteries fail altogether (but they may work again indoors if they warm-up a bit, so don’t necessarily throw them out!)

NiMh Rechargeables… Below freezing

These batteries can get below freezing, approximately into 15F (-10C). But, but they will function, they may lose some capacity, so anticipate to recharge them with greater frequency than normal to hold them working.

Lithium AA’s… The most suitable choice

These are the relatively Lithium AA camera batteries by Energizer & others. Lithium is one of reliable chemistry in cold temperatures, getting down just -20F (-30C). Remember that these are certainly not rechargeable like other lithium cells, and will NOT be used in a NiMh AA charger.

Another note…

In the matter of portable hand-held weather instruments, and home weather stations with remote sensors which feature LCD displays, you will learn that even if you might be using lithium batteries, the display goes blank just under freezing. For the reason that the LCD becomes inoperable in freezing temperatures. Don’t worry though. Either maintain your meter close to you and soon you need to take against each other for a measurement, or perhaps trust that this device is registering data even if you can’t understand the display. Home weather stations displays the remote sensor data on his or her indoor screen, and that means you will know if you find a problem.

That about covers it. Aren’t getting frustrated using your weather station performance until you’ve tried a collection of lithium batteries. Particularly if are in the cold weather by November!
