Well yeah it should be fine. However Drivesafe is going to offer one soon so that might be worth waiting for. But yes, it should do a fine job. :)Quote:

(Red constant, green on flash). The reason I ask is that mine has been like this (red constant/green flashing) for 24 hours, so I'm still waiting for it to go to the float stage.Quote:

went back to "Absorption" twice
just let it run,,,
That’s it in a nut shell ;)Quote:

Yeah - I understand that I need to just let it run - and the fact that 1.25 Amps going into a 90 and 100Ah pair of batteries dictates this - but I was more interested in the unit's actual mode of operation. Let me explain...
The documentation states that...
1) Bulk charge will go for a max of 72 hours - if the battery(s) haven't made it to 80% charge by then, the charger turns off altogether as it assumes the batteries are defective. You know when it has made it to the 80% level - which is the start of the Absorption phase, because the light changes from red constant to red constant with flashing green.
2) But here is the crux of my question - the documentation then states that this Absorption phase will only last for a max of 8 hours before kicking over to Maintenance mode (just Green light on).
But if Pedro waited a week before his charger went to maintenance - then the charger must stay in absorption for longer than 8 hours because it will only bulk charge for 72 hours max before actually turning off, if it hasn't made it to the Absorption mode phase (80% charge).
Mine has now been on absorption for 48 hours! So either the documentation is wrong, or our chargers are defective! Guess the documentation is wrong - the thing about the blokes that sell these things is that they don't know Jack about them either.
I rang a few places today and it seems I know more about the thing's operation than any of them! :eek:
Hmmm.. I don't remember a limit on time to the bulk charge.. This docco here doesn't mention it.
Maybe they have added it to the new ones? Mine would be at least two years old. However the Lotus battery is fairly small so I probably wouldn't have noticed it.
The Projecta charger I'm using on the defender doesn't have a limit to it's primary charging.
If you goggle battery fighter - look at the the 6th link.Quote:

When this happens, both the green and red lights will be on steadied. Please check battery condition...."
Mine is currently - red light on steady, green light flashing - this indicates absorption mode. But as I say, the documentation states it will only remain in this mode for a maximum of 8 hours. Mine has been like this for 48 hours. Pedro's must have too if it took 1 week to go to maintenance mode.
I sometimes see both red and green on in the lotus so maybe it's telling me it's worried about the battery. :oQuote:

The amp hour rating of your lotus battery must be near the limit (theoretically 90Ah) of the charger and the lotus battery must be near complete discharge. Seems odd as I imagine you hook it up after you have driven the vehicle. :confused:
Hi Tim
I would be pretty interested in a slow charger to maintain both the camper trailer batteries and the D2 batteries(I get flat batteries due to driving to work in the dark and its a short trip so no re-charge) Looks like I will be getting supplied a work vehicle so all the more reason to get one.
Also if you do Hi-amp bulk chargers I will also be chasing one of those for the camper trailer to charge from a gen-set when the sun is hiding.
Would rather buy from you than an Ebay unknown!!!
Thanks
Andrew
