Ref basic ion cube just purchased. I am using a 12 volt 16ah gel cel to
power cube. Spec indicate a default charge rate of 1.5 amp but actually
measuring charge current to 2600 ma battery (new) with Fuke 87 meter
equals 860 ma charge rate. Battery read 7.29 at 1 amp load before starting
charge. Will the 13.8 volt power supply you suggest get the charge current
to 1.5 amp? Does the charge rate fall off as battery is charged, thus
maybe closer to 1.5 amp with fully discharged battery?
On a single battery your 12 Volt Gel cell should be getting the Job
done.
The charge rate does fall off as the battery reaches fully charged, however
this does not happen unit the battery reaches a voltage of about 8.4
Volts. This depend on the length of charge leashes and how much equipment
you have between the battery and the Charger, (switch, charge jacks and so
on).
We would like it if you give us a call Mon-Wed so we can ask you some more
questions. Some information that would be useful is when you did your amp
test what was the VDC of that battery at that time? What is the Voltage of
your power supply.
