Hello all,
We have an issue with a battery brand I have not heard of and can't find anywhere on the web. It is an UltraTech 12120 battery (12V, 12AH). I suspect it may be Chinese, but I'm not sure.
The problem is when the system runs off of battery power for 4 hours and AC voltage is reapplied to charge the battery from a power supply, there is an initial charge current of 5A.
The spec sheet states 3A max and it takes about 2 hours for it to decline to that level.
Why the high initial charge current? Are we dealing with a cheap battery perhaps? Does anyone have any experience with this brand of battery?
Thank you for lending your expertise.
