Battery to extreme temperatures

Lithium AA Batteries - for extreme conditions

Delivers the power down to -55 º C degrees

Sometimes it is extremely cold. Even at minus degrees starting crystals in LCD displays become sluggish and difficult to see.

Good, fully Alkaline batteries can easily -20 º C, up to -30 º C. But then, when the batteries are getting discharged, or the temperature drops even more, then it will be difficult. That is when the lithium battery keep running .. They have a number of characteristics which may make them worth the money. Lithium batteries can be stored a long time. The loss during storage in 20 º C only 1% of
capacity per year. At the lower storage temperature less.

  • Lithium manganese dioxide
  • Working range from minus -55 º C to + 85 º C
  • NOTE! Do not be exposed to temperatures above 100 º C

Battery Replacement

There are several types of batteries to choose from. Read more facts about the batteries are working.

How long will the batteries?

  • Factories indicates always operating, which is longer but based on about 20 ° C. All sensors, we can sell Swedish winters, and with good alkaline batteries is the least one year.
When should I change the battery?
  • We recommend that you replace each year in late autumn. So before the batteries are totally exhausted. The reason is that they are new batteries in top shape for winter pressures. And you are not the batteries run out so that you lose data and have to change the middle of winter.
  • If you have any problems before the year has passed, check on the display if it indicates that the batteries are weak .. Some sensors are more sensitive than others for low battery voltage. Temperature Sensor is one such. The show often "OFL"

Why should I only use alkaline batteries?

  • Alkaline batteries are of good quality can chill well. What is absolutely necessary if located where it is cold.
  • Rechargeable batteries are not only inferior properties when it gets cold. The voltage is not sufficient in most systems. (1.2 V to 1,5-1,6 V)
  • At extremely low temperatures (below -30 ° C) is a special lithium battery used instead.
  • Has an energy content that makes you not need to change so often.
  • The risk of the leakage is small when the battery is changed before it is fully completed. (Ie when the device says that the battery is exhausted or a sensor stops working.)
Why it does not work when I changed the battery?
  • Most common error is that you do not immediately after you change the batteries in a sensor re-started the main unit. It must do so for that when you change the batteries in the sensor to receive the signal a new code. The main unit does not recognize it unless you ask it to listen for new sensors / transducers. This whole procedure is to your head unit should not take signals from your neighbor's donors. Some units have a button function to search for sensors again. Then you can use this function.
  • Another common mistake is that you get the batteries when they are new does not have full capacity. Note: a standard volt meter will not disclose this error. The voltage must be measured under load. If it does not work, try again with a couple of other batteries in order to exclude this.
  • Another fairly common error is that the standby batteries wrong. Check carefully arrows or symbols that indicate the plus and minus for each battery. Often 's sitting on the lot. But not always! Depending on how long and they were UPSIDE so has batteries, and perhaps unconscious equipment has suffered. Instead of 4.5 volts, it has been -1.5 V.
  • Hybrid batteries of different type / age / new / use is not good.
How can we do?
  1. Get fresh alkaline batteries. Watch the date stamp when you buy the battery. There should be at least 4-5 years. Otherwise, they are an old residue lot and there was a reason why they were so cheap. By this we mean not the most expensive is best. But the newest is often best, regardless of price.
  2. Replace the batteries in the first donor.
  3. Change the batteries in the main unit or restart immediately. (If you only have the batteries as backup for power cuts, they must not be changed, but the main unit must always be restarted if there is a search function.)
  4. It is now clear.

Facts about Batteries

There are several types of batteries to choose from. But in addition, they are fitted properly for it to work
NOTE! Especially


1 Not Rechargeable batteries

1.1 Alkaline Batteries.

Is usually used when one wants to have long operating tex. in fire, free styles and flash units to cameras. Alkaline batteries are a safe way to avoid leakage.
The alkaline battery works in the temperature range: -30 ° C to +70 ° C.
At the load voltage remains constant at 1.5 V and then rapidly decline towards the end.

1.2 Alkaline Batteries and the environment

Mature alkaline batteries are environmentally hazardous. Modern cells are labeled green alt. that there is no mercury in the battery (0% Hg). The alkaline battery is currently the most widely used battery type for use in most consumer products and is now completely free from the addition of the heavy metals mercury and cadmium. They shall also be returned when they are discarded.

Appropriate in most donors and the main units in which these take only a little power but for a long time. They can directly replace quality batteries from other manufacturers with the above size designation.

1.3 High Power batteries

New alkaline battery types of "högeffektsbatterier" (Ultra) type has been developed to meet the high load demands required by digital equipment such as digital cameras, CD / MD player and the radio-controlled cars, hallogenlampor mm.
Unnecessary in most donors and the main units in which these take only a little power but for a long time.

2 Rechargeable Batteries

2.1 Nickel Metal Hydride (NiMH) - NOTE! NOT recommended!

Life of the battery is determined mostly by how it treated. Overheating due to high out-or recharging the power to shorten the life dramatically.
If a rechargeable battery is unloaded for a long time, it will be destroyed. When, for certain rechargeable batteries mentioned "memory effect", it means that the battery, if not been fully discharged when it used, learn a new and lower level of capacity. To avoid this, battery types of this memory effect discharged fully at least every 3rd, 4th time.

2.2 Nickel Cadmium (NiCd) - NOTE! NOT recommended!

Older type of rechargeable battery.
Nickel Cadmium has the advantage that it can withstand very high power outlet for a short time, and is therefore suitable for power tools and in the hobby sector of electric model cars and airplanes. The number of charges varies depending on how the cell has been handled. 500-1000 times. is normal if you do not have fast charged cell (hence exposed to temperatures exceeding 50).
Nickel Cadmium cells have a nominal voltage of 1.2 V per cell. In order to avoid memory effect should load from the cells completely (about 1V/cell) regularly.

2.2.1 Standard Charging

Maximum laddström 0.1 x battery capacity in 14 hours.

2.2.2 Continuous maintenance charging

Laddström between 0.02 to 0.05 x capacity.

2.2.3 Fast Charge

0.3 x capacity for 5 hours.
Maximum snabbladningsström
1 x capacity in 1.5 hours.

2.2.4 Self-Discharge

ca. 20% / month.

2.2.5 Nickel Cadmium and the Environment

Nickel-cadmium is hazardous and should therefore always be returned!

2.3 Nickel Metal Hydride

Nickel Metal Hydride is an environmentally friendly alternative to nickel-cadmium.
NiMH battery has higher capacity than the equivalent NiCd battery. The number of charges varies depending on how the cell can be. 500-1000 times. is normal.
NiMH can withstand the rapid charging, but it is extra important that the charging is temperature controlled. The battery is damaged at temperatures above 40 ° C. NiMh has negligible memory effect.

2.3.1 Standard Charging

10% of capacity.

2.3.2 Self-Discharge

Expect approx. 40% / month.

2.4 Lithium-Ion (Li-ion)

Lithium-Ion battery is preferable where the need for high capacity, small volume and low weight plays a role. A Lithium-Ion battery has a cell voltage of 3.6 V and fitted with an electronic monitoring that protects the cell against too high up and discharge current.
This Battery is most often used in devices where the maximum capacity to get seats in the minimum surface and minimum weight.
Since Lithium-Ion battery is higher capacity and therefore need not be recharged as often as NiCd and NiMh batteries can therefore be seen as at least as long-lived and even longer. The number of devices is approximately 500 times.

2.4.1 Charging

Lithium-Ion battery can withstand quick charge (approximately 2h).
Since Lithium-Ion battery has no "memory effect" does not need to be reconditioned.

2.5 Lead-acid batteries

Common in tex. backup alarm installations, toys and where high power sockets may be needed for less. The tension in a blyackumulator is at 2V per cell.
Standard Charging: Blybatteriet be charged with constant voltage. A 12V battery is charging appropriate by 14.4 V for a limited period, or by 13.8 V for the continuous maintenance charge.
Appropriate laddström can be calculated to a maximum of 1 / 3 of the battery capacity, eg 12V 6.5 Ah is loaded with a maximum 6.5 / 3 = 2.16 A.

2.5.1 Fast Charge

Charge the battery with higher power (fast load) shortened the life and the capacity drops.

2.5.2 Lead-acid batteries and the Environment

Shall always be returned when the end of life. Please note that the battery acid is highly corrosive.

2.5.3 Return of environmentally hazardous batteries

The risk of environmentally hazardous batteries discarded with the ordinary waste is great because we can not always distinguish between those that are environmentally hazardous and not. To avoid data accidentally released into the environment has been, therefore, since January 1, 1998 been law to submit all types of batteries and products containing batteries.

3 Where are the batteries made?

All the shops that sell batteries have the obligation to accept old batteries, especially nickel-cadmium batteries. Many HOUSE can leave batteries in garbage collector. Check how you do with those who get your. On the environmental stations and recycling, you can also leave your batteries.
