BBU not charging the battery

(905 Views)

REPLACE BATTERY light of BBU came on.  Replaced with new battery but light came on again after about 45 days.  Figured new battery was also bad.  Charged it and light again came on after about 45 days.  Battery reads more than 14V.  Put meter on leads inside BBU that hook to battery and reading is less than .5V.  Seems to me that BBU is not supplying the trickle of charge to the battery that it should.  Is BBU faulty?
