For your weather unit it should do the job fine. In your case the current cunsumption will be very small, also alkaline have a decent energy density. Whereas for lithium-ion the capacity is barely affected by a change of temperature of 20☌ to 0☌. A solar-powered charger for rechargeable AA cells Panasonic Eneloop 1.2 volt NiMH rechargeable cells in AA and AAA. Note, just as you stated, that discharging any type of battery in the cold will negatively impact its capacity, but the effect are much higher on alkaline.įrom Energizer datasheet we can observe that for a 250mA discharge, you loose half the capacity in an alkaline at 0☌ compared to its capacity at 20☌. Higher voltage batteries such as lithium based battery (nominal 3.6-3.7 V) might definitely damage the unit. KEINE Hochleistungsbatterien oder wiederaufladbare Batterien verwenden. Verwenden Sie bei kaltem Wetter Standard-Alkali- oder Lithiumbatterien für den Außensensor. I think you should use only regular AA non-rechargeable batteries (1.5 V nominal). Kratax 1.5V Rechargeable Lithium AA Batteries, 12 Pack AA Li-ion Batteries with 2H Smart Fast Charge, 3500mWh High-Capacity, 1600 Cycles, Long-Lasting, Constant Output for Household Office Devices. Usually.Įg after a long period of use if there was a much colder than usual day the Lithium cells may still operate whjen the Alkaline one would not.īut using Alkaline and replacing periodically will probably be cheaper overall and just as good.Įxample of performance of Lithium AA cell.ġ7 page datasheet & application manual here You can finally get rid of your big and bulky battery chargers as the fast-charging USB Rechargeable Lithium AA Battery can be charged directly via USB Type-C. In the case of your weather station and given the likely minimum temperature range I'd expect the Alkaline cells to be entirely acceptable. They are useful in niche applications where their special characteristics may be of value or ecen essential, but in most cases AA Alkaline cells work almost as well and are much better value for money. They have a similar terminal voltage, higher energy content, flatter discharge curve, better low temperature operation and, usually, a much higher proce than Alkaline cells. Lithium primary (non-rechargeable) cells are available in a number of chemistries and the ones they mention are a direct replacement for AA-Alkaline ones. Lithium-Ion and "Lithium" are NOT the same. RUIHU AA Batteries, 32 Pack Lithium Iron Double A Batteries, 1.5V 3000mAh Longer Lasting AA Lithium Batteries for Flashlight, Toys, Remote Control, Non-Rechargeable (Lithium AA-32 Count) 4.2 (390) 5199 (1.62/Count) FREE delivery Wed, Apr 12.
