Nut upsuser - Jan 2008 - How to lower float charge voltage of an APC Smart UPS

Dear Sir,

 

Please tell me if u have any method to increase the charging current of
APC smart 1000/1400VA with and without external battery bank option. I
am using externally 40 and 80 Amp lead acid batteries but charging time
is too long. Please help me ASAP. 

 

 

Regards,

You would have to ask APC for that. Since the original batteries that go
into this system are only 12Ah, I can imagine that charging time will be
(very) long when empty when using the build in charger. I'm fairly certain
that this can't be done through a command that is sent to the UPS, so this
probably requires additional hardware (if it can be done at all, safely).
I expect that adding an extrenal charger might/will interfere with the
internal charging circuits, so I really doubt if this is an optimal
solution. Several vendors have systems where additional battery modules
can be added that come with their own (integrated) chargers.

Best regards, Arjen
