Explain the Optimization function. What? Would you have the charger continuously connected to the battery? I would only use this to charge a dead bat

This is a smart charger and as such it senses when to charge the battery and when not to with its built in circuitry. So yes, you could leave it hooked up to the battery indefinitely with no damage. Many people do this in the off season when a battery is sitting and not being used. Otherwise, you could be purchasing a new battery if it sits to long and discharges to the point that it can't recharge.

its a processor that recognizes the best type of charge to put in the battery ,when you start to charge, it does it automatically

If you're trying to revive a dead battery, you want the NOCO Genius G3500. It has a repair function that is amazing. May take a couple days on a car battery but well worth the money. Yes, this is a very smart charger you can and should leave it connected to batteries that sit.

I am guessing you are making reference to - "Great as long as you have a full charge on your battery to start. It was not very clear that it would not hold the battery state if it was not at a full charge." But then you read another and they are stating "After much contemplation and research,,, and calling the manufacturer I've been informed (buy the manufacturer) that this unit does NOT have any method of charge control. Beware! ... you can easily overcharge your battery(s) with this unit." I can tell you that I did put it on a low battery in my truck that had been parked and it charged it up just fine, not in one day but a week or so. As for over charging that too is a no brainer, without a control or regulator you run that chance. That is why I bought the Schumacher SPC-7A 12 Volt Solar Charge Controller and have no problems. This is the ticket if you have a vehicle parked for periods of time. If you had tons of electronics that are a draw on the battery it might not keep up.

I would NOT recommend that you do this.. It can probably be done but this charger monitors a battery for the level of discharge as well as the level of charge. If it were the exact same battery with the exact level of discharge maybe but I don't see that happening.. I would NOT recommend you do this..

To the best of my knowledge, any decent NiMH should work.... Its my opinion that the low discharge rate batteries, such as Imedion or Eneloops are the best batteries available these days, not since they offer the greatest capacity, but since their low discharge rate allows them to sit unused for greater periods of time, and still deliver when needed. A device such as the PortaPow might sit in your glove box for months or years before being needed. To then find the bats dead makes no sense.If you are using the portapow daily, well, I'd think there are better ways to charge your portable device....

I have one of these and to be honest, I put it on charge overnight after I have just used it and once every few weeks to top it up and I use it often as I have a lot of "toys" - 2 tractors, 2 trucks and other stuff and it is always there ready to do its job. There is always enough there.In answer to your question... I really don't know, but I would not chance it given the performance of it when charging it as directed. I wouldn't take a chance.Hope this helps.

Hope it works out for you. I had some battery issues in the beginning. After manually charging the unit, it seems to maintain a 3.85V charge or better. Time will tell if this makes a difference. And for $250, you'd think they would include a twenty-five cent mini-USB cable to charge it up.

As it runs, it charges the battery as an automotive engine would. However, I bought an inexpensive "float" charger that I keep in the battery at all times. Do not confuse with "trickle" charger, which can harm the battery. The "float" charger keeps the batter charged, and shuts off when it's no longer needed. The "trickle" constantly charges, and overcharges the battery. They're about $5.00 at Harbor Freight. Hope this helps.

I bought a trickle charger that automatically shuts off when fully charged so as not to overheat the battery. I never paid attention to how long it takes, but would recommend investing in such a charger to save the battery. The charger can be used for other batteries as well.

The question posted by Barbara Kennedy was "how fast does it work?". This is a battery maintainer or float charger. It is not suitable for recharging a depleted or drained battery so charge time is not normally discussed relative to this product. If you need a proper battery charger there are many better suited to the task than this product which is aimed at keeping full charge in a battery that is used in a vehicle which is not frequently used.

Good question. I would ask the manufacturer I had a question of them once and they were fairly prompt in answering. With mine I only need to connect to the batteries on my pick up camper and charge away!

I would recommend getting a electrical charger. This one is more for something that you don't drive very often like a atv or a lawnmower. This only being 2.4 watts, isn't powerful enough to charge a car battery. It's really just for maintaining. I bet it would take a long time to fully charge a car battery.

I advise u not to charge it with a different charger b'couse it may cause defect on it . The battery can support a certain A or volts but it was designed to measure when it's full charged or empty , what i'm trying to say it's u can short the batery life if u use the wrong charger .

It works fine for any size battery. A slower charge is better for the battery as it creates less heat. If you are not in a rush this will work fine. For your battery, it will take it from a state of charge of 50% t0 90% in under 5 hours and will have it topped off by 7 hours or so. I like this charger so well, I'm buying two more. One to put a winter maintenance charge on all my equipment batteries, and one as a permanent install on a car. I have the 10 Amp version which I'm also very pleased with. I use in to charge my boat battery which is a little small but I'll be swapping it out for two larger batteries. It works fine for any size battery.

i do not think that it would profit you to do so, in theory you would be 1/2ing the capability of the charger. i can not see the advantage of this.

You could do that, sure, but the idea of the charger is to maintain, not recharge. They should call it a maintainer instead! It won't charge a dead battery; rather, it'll keep a live battery from going dead. So--if you know the battery is live, you might do as you've said, but if your trailer was mine, I'd keep the battery attached to the charger full time. That's what I do, and it works. Eric

To some extent, it does a more complete job of charging without overcharging. I found out that I wasn't charging my deep cycle battery enough with the car charger I was using - this critter worked on that battery for about 36 hours before saying it was charged, and the battery worked much better afterwards. At the very least it can eliminate battery problems caused by operator error. ;)If you're considering getting one of these, just get it! It saves a lot of time and reduces the number of things you have to worry about on the boat.
