I put the cells with a Garmin Oregon 400t a (an outdoor navigation device).
For these high power consumers the Lithium AA batteries are ideally suited. The voltage curve during discharging is excellent straight - this means that the equipment is supplied over the entire useful life always with the same voltage, so this does not fall continuously.
A further advantage of the battery is the voltage of the cell by about 1.5 V.
Rechargeable batteries have a voltage of 1.2 V - here the useful voltage falls below quickly with electronic equipment.
The capacity can I describe to you only comparative in connection with my Navi:
- Alkaline manganese batteries last only a few hours with continuing reports that the screen brightness can not be maintained.
- Batteries (Nickel Metal Hydride 2000mA Lidl AA Mignon) hold something twice as long, and at the end of the device gets off abruptly. In addition, strong discharge during storage or Nichtnutzung- a charger must always be there.
- Lithium AA batteries can be about 5x as long as 2000mA battery use without any error messages. After turning off the unit, I have found a cell recovery and they can still be use for a while further. At Battery low storages have possibly. Be made immediately, since the voltage drops off rapidly now (compared with battery but there is enough time). Further, no discharge when not in use.
Conclusion:
++ Excellent high capacity for a battery
++ Excellent constant voltage across the entire discharge area
++ Durability: 12 years
++ Very well made
- Quite expensive
