What we found

  • 11 batteries are explicitly documented as NOT to be charged with it.
  • 6 specifications are published for it, each with the source it was read from.
  • No matching recall was found in the records this catalogue holds from 7 regulators.

Assembled from the evidence on this page. Every figure and count below is shown with the source it was read from.

Other findings

Bulk charge voltage
14.4 V in Bulk, entered only from a discharged battery

“If the output current reaches its maximum (normally caused by a discharged battery), this will cause the converter to go into Bulk Mode, which means the target output voltage will change to 14.4 VDC and a timer will start.”

Bulk mode duration
Bulk ends at about 5 A of draw, or after 4 hours

“Bulk Mode will be maintained until the current draw drops to approximately five Amps, or until the timer reaches four hours (whichever happens first). Then the target output voltage is changed back to 13.6 VDC for Absorption Mode.”

Charging stages
Three stages — Bulk, Absorption, Float

“The 3-Stage “smart” charger continuously measures the battery voltage output and regulates the amount of charge using three modes of operation; Absorption, Bulk and Float modes.”

Designed for battery type
Drawn against a 12 V deep-cycle battery

“12 Vdc DEEP CYCLE BATTERY”

Nominal output voltage
13.6 V nominal — the mode it holds in normal use

“The converter normally provides a constant target output voltage of 13.6 VDC (nominal) to power all the branch circuits.”

Output voltage verification
13.6 V ±0.2 with no load means it is working

“If the voltage reads 13.6 VDC (+/- 0.2) with no load, the converter is functioning properly.”
