Battery Chargers - How I Did It -

i use this . . . . (NEG to chassis)(they do an M8 eyelet version too)

Thanks again! I used a "multi-meter" to look up a strong - NEG point while holding the other end in the + POS, so that I measure a steady 12.x voltage. I should be fine

Our posts crossed, but that's a convenient part. Cant really go wrong there, even if the wife needs to do it.

@Dellmassive is this a faulty charger do you think?
Van is off and locked. Victron IP65 12/25 charger has been connected for about 48 hours now. It correctly moved to Storage mode after Absorbsion charge… but 13.9A !!??? That can’t be right!?

Unlikely, the victrin kit is very sturdy. But a possibility.

What charger? 15A? - Edit IP65 12v 25A

Screenshot the settings page to see what profile it's set to... AGM? - Gell?

Did you have a dc-dc charger and leisure battery.? - that might have powered up and charging your LB aswell?

Have you a voltmeter to confirm the voltage? - to see if it agrees.

Is the charger warm)hot/cold? - warm would confirm it delivering power,

If you remove one clip does the current drop down to 0A?

........


FYI.... The storage mode kicks in after absorption, but there is a time limit on the absorption ( ie 2hrs max - see the charge profile in the battery settings).... So it's possibly the battery's are not fully charged yet And are continuing to charge via the storage mode... One easy check it to start a new charger cycle by pressing the mode button. Or switching the charger off and back on again at the mains. or by removing one clip and put in it back on again.

When a new charge cycle restarts - if it moves into storage mode again within five minutes or so,

then the chances are the battery is charged,

but if it carries ongoing in bulk/absorbtion for hours then you know the battery wasn't charged and it just timed out in the absorption mode.



id imagine you have a dc-dc charger and the victron is charging both batterys. . . . in which case it may take 4days to fully charge a low SB + LB with a 25A charger.


let us know what you see, and post some pics if the setup - that helps loads.
