Battery:
I am using a battery pack for my project that has SB540, Schottky rectifier, connected across the battery cells' poles. This is to protect against reverse polarity connection, I assume.
The battery pack consists of two primary cells, Tadiran SL-2780, connected in series (7.2V output). Each cell has its own diode. Therefore, two diodes exist in battery pack. Battery chemistry is lithium thionyl chloride inorganic electrolyte.
What is the question?
My project is running very low on power as mostly it is in deep sleep mode and consumes about 7uA.
Q1. Considering this little consumption, and the chance of connecting the battery in wrong polarity is almost zero, is it a good idea to remove the diodes to prolong battery lifetime?
Q2. Do diodes, in this configuration, use energy and dissipate as heat? (we know that ideal theories do not apply in reality and all diodes have leakage in reverse.) I would like to prevent any energy loss, even small ones in uA range.
BTW, I have already seen this topic.
