Can the Gen 1 10 amp charger be left permanently attached to a marine battery even when the battery is in use and being charged by an alternator?

Yes, it's designed to be connected to a battery permanently. It is supplied with ring terminals instead of clamps for a permanent connection. There is nothing to set or adjust. It has only a pair of indicator lights to tell the state of charging at any time. Before I bought this, I called the factory to verify everything. It can be connected to the battery, plugged in and forgotten about.

yes it can plus,you leave it plugged up all the time when you have it moored or parked on the Trailer. It will keep your Batteries maintained and they will last you much longer.

It shouldn't be a problem. An alternator only supplies 13 volts which shouldn't affect the charger. It would simply interpret this as a fully charged battery and go into a hold mode.

I would think it would charge it no problem. I would leave it in maintenance mode or automatic mode, to prevent damage to the battery .. the chargers do a good job deciding what mode works best depending on the battery voltage. I have mine running to marine 12 volts and two 6 volts hooked in series. When they are pretty much drained it will take around an hour to bring them back. What i like is if I'm using a lot of power it will adjust its output automatically..

My understanding is that it can be left on... indefinitely. That's what I'm currently doing for my 48V electric bike. Per literature with the "Save A Battery 2365-48 48-volt Battery Charger and Maintainer", "Extends battery life the longer it is plugged in".

It may not get the battery to a peak of 14.4V, but it will get it to a close to full charge condition. However, remember this thing charges at about 1 Amp. For a Marine Battery, it will take a long time if it is discharged. It will work fine if you are only trying to keep it at full charge.

I can't give any specific advice on this charger, however, I wii say that you would be better off with a different kind of charger. I purchased, the second charger, from Amazon and it is a "Battery Tender Jr." . It costs about double but you will make that difference back in extended battery life as well as in being certain that your battery will always be ready to start your generator. The one I recommend is left plugged in to your machine and it keeps your battery in top shape without the damage that occurs by leaving a normal trickle charger plugged all the time. The unit comes with a plug that you connect to your battery and has a quick disconnect that you should use when starting ang operating the machine. Watch the polarity. Good luck.

Using this as a "power supply" is not recommended with sensitive d.c. electronics (radios, test equipment) and such. Car battery chargers don't have "clean d.c. output filtering. But you can attach charger to an auto/marine, etc. type battery and then connect to the battery then. The battery acts somewhat like a filter and your current should be acceptable. I've only done this in an emergency 2 or 3 times in the past 50 years, but it works. Otherwise straight out of the charger could damage "high end" electronics. Straight out of the charger to a radio, you'll probably notice an over bearing loud Hum coming from the speakers, that's unfiltered d.c. Good luck in your experimenting!!!

Yes, But you will have to periodically keep re-charging that Marine battery! Hooked up and turned on means the Inverter is pulling a bit of current even when nothing is plugged into it, To not use up the battery you need to just turn it on when needed. Make sure you put fuses from the battery to the inverter also!

Yes this charger works fine for deep cycle marine batteries. I charge my deep cycles all the time with this charger.

Yes, I keep them hooked up to 3 batteries that power my trolling motor on my boat. They do a wonderful job and while sloppier, have lasted much better than those "boat" battery charging units that coast enough to buy ten of these. I keep three of these hooked up all the time.

Yes. My boat has an automatic on-board charger. Any 12volt automatic charger will work.

i understand battery charger should not be wired to the battery while the vehicle is in use. good luck.

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.

I say , yes . I have had mine out charging my boat battery for a couple years now . It is important to secure them well so they don't rattle around in the wind and break a connection .

i don't have the unit or manual immediately available but it certainly will not damage the batteries as the batteries are not charged by the adapter...the aa batteries are a completely separate system. the internal rechargeable battery should not be damaged either as that is a normal output for a charger. HOWEVER, i would suggest that you look up this unit's manual on the web before purchase and download it to be sure (virtually every manual known to man is there somewhere!) -- i honestly don't remember what the recommended output is for the charger for this unit. if i am back at my boat soon i will look at my manual to be sure and update this response if i am incorrect in my assumption. do check first! i don't have the unit or manual immediately available but it certainly will not damage the batteries as the batteries are not charged by the adapter...the aa batteries are a completely separate system. the internal rechargeable battery should not be damaged either as that is a normal output for a charger.

Manual says you can charge marine battery but you have to remove the battery from the boat and charge on shore. To charge while connected, you need a special charger that is designed for marine use.I think they are trying to say it'll work but the charger is not water-resistant.

You can leave the battery in your vehicle still connected to your battery cables; however, I bought two of these chargers, and they both died within a year. I bought Schumacher PS-1562A DSR ProSeries 1.5 Amp 6/12 Volt Automatic Battery Charger/Maintainer , and have used it many more times than the Tender model, and have had NO problems with it. It automatically detects whether the battery you hook it to is 6 or 12 volts- no need to do that yourself on a switch selector. Go with the Schumacher!

I would not. You could easily overcharge the battery where as a regular charger has a regulator on it. This is to be used to charge another vehicle/motorcycle for a short time; until the other vehicle can be started.
