Is it good to constantly charge a power pack? Is this "AGM" a different unique battery that can handle such versus others (or why the differences)?

If you can remember to plug it in an hour a week that would be great (or even once a month). However, some chargers like the Duracell/Xantrex can switch between two levels of charging so when the battery is full it will shift to a trickle charge so to not over charge the battery (this only works for AC charging- not DC). This is why the powerpack will flash the charging light and then go to a steady light when it is full...

I've left mine charging for several days, and have never had performance issues with the battery. I know that's purely anecdotal, but its not something I've ever had an issue with.

I keep it plugged and use it every morning so I never have it run out of charge. I think it will run O. K. if you have to plug it to finish in the event the battery runs out.

Yes. I alternate using the original battery and the Anker ones, every week or two. And always charge the reserve batteries using the Anker charger. They both take several hours to get a full charge, but then stay at 100% for a long time, more than a week for sure.It's nice to have a back up battery always with me!

I would have to look it up in the manual. Some deep cycle batteries like AGM's require a higher than standard voltage for charging. Perhaps you can download the Owners Manual pdf online.

I am not using it on AGM batteries, but they are just lead acid batteries in a more efficient configuration, so I wouldn't be afraid to use this battery charger on AGM batteries.

It also depends on if you are using it as the primary. AGM batteries do not like to sit for long periods of time. If you are letting them sit, either use the charger or remove the battery from the vehicle. If you are using it for your DD then you are fine, provided most of your trips are over 10 minutes, as that is around the amount time needed to charge the battery.

Very simple, it comes with a A/C plug that plugs in the front of the battery pack and never have to worry about the charge status. i use mine daily so I leave it plugged in all the time and it has never hurt the battery pack and over the last ten years I am on my third one which is not bad compared to the daily use.

I use the 1 to 5 for charging hi-capacity batteries with no problems. It takes longer than charging just one, but that is to be expected. I'm not aware of any alternatives.

I have used both batteries for over a year now. No damage to the camera, long battery life for both. I have not had to use the power pack as most of the shooting I do is during my hikes.

I run the generator once a month for 15 minutes. I have not yet any problems with the battery needing charging. Hope this helps you out.

I use a Genius G3500 Charger/Maintainer. It has a special charging mode for AGM batteries.Just make sure to use a charging system that is smart enough to charge and manage AGM batteries.By the way, the Vmaxtanks MR107 12v 85AH battery is wonderful. I highly recommend this product.

" the battery sounds like it is boiling water ", I am not sure how the voince sounds? Such louder or not? Charging the battery, there will be voice, it's normal.But we didn't test on AGM battery before, cause few people knows AGM in china.So sounds is normal, I think you can charging it first, then see if the storage power improving?

Don't use a car battery, get an AGM battery. They are more expensive but worth it.

It is very hard to answer such a broad based question. Is it worth it? That would depend if you could find something better at the same price or less, and it would depend on whether having some kind of back up was better than not having anything at all. You can find better backup battery packs with higher capacity that charge from plug into a usb outlet or wall, but then you can't charge from a panel. What this kit gives you is versatility. You can charge the pack from a car cigarette outlet or the solar panel. You can remove the batteries and charge more while using the charged batteries in something else. You could even charge your car battery with the panel (although it would take many weeks). You can supply 12V to any cig plug device (within the current output) with just the panel and you can charge a USB device from the pack, without needing the panel. So, in my opinion, yes, it's worth it. It gives you options, which are very important if you're suddenly without any power outlets. And if you get a "bad one" try reseating the batteries and if it doesn't work right return it, that's the beauty of Amazon.

I do not think you should. There are specifics that you need to watch while charging AGM Batteries. You really should have a charger with a voltage meter so you can make sure you do not over charge and damage the battery.

The smaller battery pack probably will not last that long. Maybe if you charge one pack while using the other. They sell a larger 5-cell pack that might go that long. I have never used mine continuously like that, but they do hold up for a good long time.
