Can this charger be used to charge an AGM 100Ah battery from a generator ? We have an off grid cabin with a few solar panels and battery bank.

I would say YES! This charger is extremely versatile and its charge cycle includes a "rejuvenation" mode that will desulphite cells in lead acid batteries such as typically used for your solar array which is a extremely handy function. Due to its charge modes you should have no problems with ANY Lead Acid battery no matter what size. Using it at night when you are running a generator should significantly increase the lifetime of your main battery bank (one 12 Volt battery at a time and rotating through multiple batteries one at a time) Occasionally, after charging, I like to jostle the battery I just charged to allow any loose scale to fall to the bottom of the battery.

I don't know why it wouldn't work if you have the requisite 110 volt AC 0.65 amp voltage to plug into. It is specifically for AGM technology. On the side of the device it says you can contact "batteryminders.com" with questions.

No. "Work" is relative here. Sure, you could get a 2A 12V charge if your genny gives clean 110V AC, but if your running a genny, you surely want to hook it up to a stronger charger to pump the batteries up more quickly.Using this item would be like putting small kiddie bike tires on a Corvette - you've got a lot of power, but you're bottlenecking it where the rubber meets the road.

I am using this charger on a 10Ah battery in the trunk of a street rod, and am completely satisfied with its performance. You might be happier with a rapid AGM charger, since that might minimize the time your generator would need to run. This charger slows down the charging as the battery nears full charge, then goes into maintain mode (charging, allowing slight discharge, then charging again to keep it at full charge).

If the generator has clean output I see no reason that the BatteryMinder AGM could fail to charge a big AGM battery. A cleaner solution might be to charge the bank direct from the solar cells, as long as the solar array doesn't have enough power to overcharge the AGM bank.

Yes. I presently use it to do the very application you have inquired about.

We used this in an off grid setup with solar panels and wind turbine. The transfer switch is useless in this setup and you need other parts for it to work properly. But yes this can be used off grid and works especially well for a back up generator for when there isn't enough wind or solar, although I must admit that ours hasn't turned on in months or even years as it is setup to kick on automatically when the voltage in the batteries hits a critical low and that hasn't happened in a while due to an abundance of solar panels. This generator is certainly not cost effective to power a house for any number of days, without grid, solar, wind and/or batteries.

I would not recommend extended use on the AGM batteries. It's OK to use on occasion if you need a quick boost. The charging profile on a lead acid battery and an AGM battery are different and over time this charger could shorten the service time/life of an AGM battery.

I haven't made time to try the new charger - I have a 2000 watt Yamaha generator I wasHoping to use - the charger uses up to 1800 watts - my generator is rated at 1650 continuousI wouldn't even consider a 1000 watt generator!Bottom line is charger will use the mostEnergy on a fully discharged battery set. If you are just topping of batteries it will use less. 1 kw generator - I wouldn't do it!

Sorry, I can't see how that could possibly work as this device charges AA and AAA sized batteries from a standard 125VAC outlet/power source. I have no idea what would happen if you connected and 12VDC battery or solar panel to it, but I'd bet that it wouldn't be good. A better idea would be to find a small 12VDC to 125VAC inverter to connect your solar panel to, and plug this charger into the inverter. Yet another idea, see if Duracell, Energizer, or any aftermarket manufacturer actually make an automotive/12VDC charger. Good luck.

I purchased this as an outside power source for my ham radio 100W, so I honestly do not know about your particular application.

Yes it is. In fact no matter what type of vehicle even if like me you have upgraded to multiple AGM batteries this charger will work for you. It is simple to use (one button operation) and the microprocessor inside the charger ensures you don't overcharge your battery(s) even if its hooked up for months at a time.

should work fine off a battery and using this to keep it charged.. shouldn't used it directly because of voltage fluctuations with clouds and weather.. will put out up to 6 amps in good sunlight...

I would say most likely not because as the batteries recharge the unit would bounce on and off as they recharge/discharge. Solution is to increase your battery bank size. My APS1000-12 has been working for over 2 years 24hr a day. But I have a bank of 12 batteries and monitor it daily to prevent totally discharging them down to 10.5 volts. This time of year my solar panels don't produce the amps as in summer months... It's a great unit but remember for every amp produced on the 120 volt side it pulls 10 amps on the 12 volts side.

You can do this but it will take a long time to fully charge. With only one generator, you will get about 0.1 amp into your 12V battery.

Yep they will work with AGM's, I don't have a boat, so I can't answer that part, but as far as the batteries go this is a great charger for them. I would say as long as the battery bank is in a dry area you should be good to go.

Not to my knowledge, I sent 2 of these units back, first one failed and the second failed as well on 110V. This charger might be OK for small batteries but not worth it for any car or truck battery. I would not recommend it at all.

It probably does, but keep in mind that different batteries require different floating voltage ("maintenance mode" in other words). This charger has no voltage adjustments. For an expensive AGM battery you will want a better charger, the one that would allow voltage regulation, and also has a temperature compensation.

If you are using it in a Generac Generator there is a small port in the front of the generator to plug in the charger that came with the generator. You can also do as Dennis replied and use a Battery Tender Junior. I usually top mine off once a month with the Tender Junior.

Its a decent trickle charger for its cost. AGMs will do fine save one drawback, this charger float charges at 14.2V, which is a bit high for AGMs, as they prefer to be floated around 13.8V. Its not a hazard because AGMs will tolerate up to 14.4V, but at the cost of battery life

I use it to charge my AGM battery bank at my cabin and it seems to work fine.

It specifically says in the instructions that it is not recommended for that. I did not know that before I bought it. I bought it specifically to use it with an Exide deep cycle battery. http://www.amazon.com/gp/product/B003FFTFBW/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 The charger maintains the battery's charge just fine, but I simply use it to keep the battery topped off for emergency situations. If I had it to do over again, I would probably get a more robust charger that puts out more amperage, say 5-10 amps.
