Note:
Please make sure the battery is inserted correctly for
its polarity as the system needs its initial power from
this backup battery to start up the system before the
solar panel charges up the accumulator and supply
system power afterward.
when in high altitude areas, during wintertime, the
sunshine time is short, and the system needs to be
powered from this backup battery, we recommend
Lithium batteries to be used for cold weather climates.
Please avoid alkaline batteries, especially when the
internal heater is to be activated during cold and wet
weather conditions as when the heater is activated, the
trapped heat inside will warm up internally, and
alkaline batteries are extremely susceptible to leakage
when the temperature is over certain limits.
Alkaline batteries can be used also, avoid rechargeabl
e battery type of NiMh or NiCd.
