357/LR44 battery question

#1 Post by kimi » 09 Mar 2022, 22:30

Can someone tell me how the silver oxide 357 size button cell batteries compare to LR44 button cell alkalines in terms of run time? (For instance, in a Pelican L1). Is there a difference between silver oxide and alkaline in terms of run-time? When I swapped out the LR44s in my L1 for the 357s, I saw a noticeable improvement in brightness...but at $2.00 a pop for the 357s versus 50 cents for the LR44s, an increase in run-time would be nice, too! Any assistance would be really helpful...

The 357 cell chemistry is 'silver' based; rated 1.55 V (nominal)195 mAh vs the LR44 alkaline chemistry, rated 1.5 V (nominal) 110 mAh.

The silver (Zn/Ag O) has a very flat discharge rate vs a sloping rate of alkaline.
