We re going to be dry camping next week for 4 days. We have 2 12v "marine deep cycle" batteries under a year old. Our on board charger is a Wfco 45 amp. I know they are basically junk and I should get a PD 45 amp.The Wfco almost never goes into 14.4 volt mode.Can I add a stand alone charger to help bring my batteries back up in the morning off an inverter generator ? Will the additional charger put out the 14.4 ? How many amps do yo recommend as an add on ?Sorry about all the questions, I don't want to damage anything and can't afford the PD yet.

just a cost referencethe 40amp Vector that some of us have, was Near $100 when it was availableno longer being mfg, don't know why, maybe NOT enough profit margini would not get anything less than 20-25 amps unless it was emergence have to have, i can't see paying $49 for a 15amp charger

“How many amps do yo recommend as an add on ?”Batteries slowly lower what they will accept as the charging process proceeds. That’s why the absorbion phase takes so long. Solar is perfect for bulk, absorb and float.

MrWizard I have seen you on here for years and recognize your knowledge of electrical problems. I am glad you responded.If I add a 25 amp stand alone, it is 25 more amps but still only 12 v or 13.6 volts. If I use the stand alone in addition to my WFCO 45 will I get a quicker charge ?

I will also be using a Wen 2000 I generator to charge. I have the direct 12 v charge cables that plug straight into the generator.Would this be a better option ?

Most of the generators that use direct 12V charge cables only put out about 10A through them.Bill
