Biggest concern the power cell is expensive to replace how many years should it last? How do you store it in the off season?

as for the off season we don't have one in florida.My battery is doing just fine no problems and the unit is worth the cost.

It is a lithium ion battery and should last for a long time when charged properly. I am not sure how many charge cycles that is, but I would guess around 1000

I've had mine for one winter and two summers now. I believe their recommendation is to leave the batteries unplugged, but to charge them up once or twice during the winter. I stored mine in an unheated garage, but I doubt it got below freezing in there. My advice is to take the batteries into the house if you have concerns over the winter. I haven't noticed any degradation in power or longevity in mine. Hope it helps.

We store ours in the garage, nothing special. Have not had an issue with power cell yet. I will say that my husband absolutely loves this thing and thinks its the best tool he ever bought!

I would suggest keeping it in the frig if you can't use within six months. That is how I store mine.

I used mine for 1 season. Kept charged over winter inside. Next season battery would not hold a charge. Took it to repair center and was told it needs new batter at $199. Bought a new Black & decker electric mower for $199 instead

you must have an expensive battery backup to store power 8,000 more bucks at least, also you can bank your energy if you are tied to the grid for future use.

My first battery lasted 3 years. I kept it in the basement during the winter and charged it every month. But when using it during the summer, I sometimes forgot to disconnect the charger the next day. This didn't happen a lot - maybe only 2 or 3 times a year. I didn't start to notice any problem until the end of the third year. I bought a new battery last spring. I've been more careful with this one and have always removed the charger within a few hours after the light turns green. This battery is still working very well, but it's too soon to know whether it will last more than 3 years.

I use Duracell batteries, but I do not use it in the same environment as you. I guess would check every 30 days or so. I would worry more about the electricity going out.

As other respondents have noted, Without getting too technical rechargeable batteries have a unspecified amount of parasitic loss depending on battery chemistry type and overall capacity.In this case the extremely large capacity of this battery will allow it store a sizable amount of energy even after a period as long as 6 months. Keep in mind that batteries like a room temperature 74 degrees Fahrenheit plus or minus a few degrees . So try and keep them in a nice cool area with plenty of fresh moving air and a very low humidity

If you are going to use it a lot get a deep cycle marine battery and buy a trickel charger and keep it plugged in while you have it stored. We use ours at a private club and throw about 10,000 targets a year out of 5 throwers (traps) and have not had a problem.

they should be stored for "off season" at about 40% (two lights). the new toro 48V trimmer has a storage feature that maintains batteries at 40% level. storing fully drained will definitely damage the cells. my lithium batteries for *all* my devices (power tools, garden tools, etc) regardless of brand came from the mfr with about 40% charge state.

I have had mine about a year and use it 2-4x month, no issues this far. I do take good care of it and clean it after each use, store it inside.

i dont take it off my battery ,i run a 1200 watt inverter in a 3/4 inch box with a lid which has a cut out for out lets with a dome light cig lighter and alarm with toggle switch out side has a poly rope rated for 500 pounds rolled up handles on each end off box, i run a small compressor with a 90 led watt bulb plus my 32 inch led tv and a 300 watt heater and lap top.i dont run it all day its my er travel pack. i can run it for a week full charge on my 12 volt battery charge time may be a full week for a low battery, i use a marine battery and 150 amp fuse hook up just in case. the main thing is the solar panel facing direction and elevation direction . my plan is to go off grid in next few years.leave it hooked up and leave it alone.. this is all new to me but i must say what i done works for me, good luck out there ..i own a solar book and read that it dont pay to go 100 percent off grid at my age but if your young start now if thats your dream.

I agree with David Banker. Your most expensive part of setting up any wind, solar, or other green energy project will be your infrastructure. Batteries, wire, charge controllers, converters, fuses, brackets, screws and paint. You will have $2,000 into your project. This is a lot of money and time to put into a project like this. But it pays for itself each year when I loose power for four to eighteen days. I set mine up for just a freezer and I had to add another 300 Watt panels due to the winter solstice. And I live in Nor Cal.

Ours is going into the third year with pretty regular use. Be sure you select only an alkaline battery or the new Quantum series by Duracell, with an expiry date quite a ways out.

I've only had the system for a few months, so can't speak for long-term use. The instrument array has a small solar cell that charges an internal battery. The inside console uses three "C" cells or a supplied transformer. The accompanying owner's manual suggests the "C" cells will last for about a year.

This lantern is designed to use battery power unless the batteries are removed from the unit. So if you seek to always have it ready for emergency or otherwise, I would consider an alternative brand, better yet concept. Consider either purchasing rechargeable batteries or a lantern that is solar powered with rechargeable batteries. This way, you will not have to replace every 40 hours ($cost $6 each time) and will always have power for when you need the lantern. Also, you will not have to drive to the store and purchase saving gas not to mention the landfill on throw aways. There are a number of choices, such as from World Green Products. hope this helps.

Believe me you will get plenty of service Life, and I plan on replacing it in another 10 years! Just keep it on the Charger, no Problems here, and it still works like new!

This unit just came to market so as far as life span no one knows yet. But I will answer on previous model. If you take care of it like anything else; it should last a long time. I used my DC44 about fifteen minutes daily on average and had it for about two years and never replaced battery or had the need to. The run time never diminished over the two years and nothing broke on it either. Just take care of it ie. taking out the wound up hair in the beater bar and cleaning filter once in awhile you will be ok.
