Charger 1Ah Battery Temp
#1
Hi All,

Me again, trying to absorve as much as I can....

Im charging a battery at 1Amh (Theorically) maybe is getting a bit less than that, and Im getting Temp readings with my temp gun of 47C degrees = 116.6F degrees

What is the acceptable max degrees per cell... allowed .. cell is a Samsung ICR....26F


Thanks is advanced.

You are charging with 1A. A= current. Ah = Capacity.

How are you charging it? In an Opus? I wouldnt state 47C is overly warm but its for sure in the top end.
How much capacity do that cell have left?

You still dont charge with "Ah/mAh". Its A or mA....

I dont think the temperature is an issue as long as they perform capacity wise.
