Hi all.
I have a battery bank of 32 75Ah AGM batteries configured in a 24V system. I'm quite baffled to read in the spec sheet that charging temperature is 0~40°C while discharging temp is -15~50°C.
How sensitive are they really below zero? Can I trickle charge them to keep them topped up or would they be damaged? I have sent an e-mail to the manufacturer but got no reply. Attached is the data sheet.
I do have some other AGM UPS batteries that specify charging down to -15. Seems strange to me that the chemistry would be so different. Just wondering if someone knows something I don't know about this.
