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.

Of course, we accept batteries for proper environmental management.
