is this charger good for 4 months of storage in an unheated barn

I believe so. The directions say they can even be used outside if protected from the weather. These units are both a charger and a charge maintainer for both 6 & 12 volt batteries.

I keep my bike in an unheated garage, but then I live in the high desert..elevation around 4000 feet. I haven't used the charger during the coldest part of our year yet...that's coming around the corner. Right now our night temps are around 40 to 50....not too bad...and the charger works like a champ. The true test will be late Dec to late Feb. I'll be able to answer your question after I've had the charger for a season.

I disassembled an old unit that failed to charge after a year or so and removed the batteries. They would not charge with a "hobby" charger designed for electric RC cars and such. I then discovered that storing the unit in the charger when it is plugged in was overcharging the batteries. I have another unit about 4-5 years old that is still going strong. I charge the batteries overnight when they will no longer last a full brushing cycle. NiCad and NiMH batteries have a very limited life when charged to 100% capacity repeatedly.

No, it will stay charged for a for a good 6 weeks without being used in moderate weather. For the first 2 years I owned mine, I left it outside in the cab of the truck during the winter (which I think I should not have done) now this third winter I find it not hold a charge very well left outside during the winter months. It has a charger for the vehicle but that charger will not automatically cut off when fully charged which could overcharge the booster pack -- may hurt the rechargeable batteries; the AC wall charger will automatically cut off when the booster pack fully charged. Now last summer I was able to do 2-3 vehicles before having to recharge the booster pack. I hope I have answered your questions

I bought and installed mine 2 years ago in an exposed outdoor location. I'm located in northern NJ and the unit is like new and works perfectly. It has survived numerous downpours, a few tropical storms, superstorm Sandy, several weeks of below freezing temps and several snow storms. Granted I shut that circuit off in the winter but there's been no evidence of wear and tear. I have it installed on a stake I've set in the ground so in winter I put a bucket over it to keep the snow off it. The box has no gaskets and isn't sealed up tight to make it weather proof. Whatever moisture gets in seems to easily find its way out. I was a little worried like you before I bought it but it seems to hold up very well.

I havent had any issues with the charger draining the batteries Ive left it unpluged for 6 weeks and didn't lose a volt on my guage. You might want to check to see if anything else might be draining you batteries its uncommon for a charger to do that.

As others have indicated this is a 240 volt appliance fused to 40 amps. I think the question is whether the business end can be left outside while the charger is inside. If so, the answer is yes, but probably makes good sense to keep it literally off the ground. A very basic hook screwed into an outside wall would allow you to keep it "in the air".

No. I have had one four years and store it outside in a shed over the winter (without batteries) in zone 6 and it has worked fine.

That is the purpose of that unit. It is a battery charger AND maintainer.Mine has been connected for over 3 months.Andreas

I DONT RECOMMEND USING A TIMER ON THIS DESIGN OF CHARGER, when the timer drops power to the battery then the light on the charger will stay lite up by using the battery (that you where charging) power. It doesn't get hot. I leave 1 (of this model) on each of my atv & jetski when ever my stuff sits for roughly over 2-3mths.I mainly leave mine on through the winter months.I have another brand (a old obsolete design I left a review on also) permanently mounted on my mower.After a couple years Id recommend topping off the battery with water if needed.Ive used trickle chargers for about 10ish years I DONT RECOMMEND USING A TIMER ON THIS DESIGN OF CHARGER, when the timer drops power to the battery then the light on the charger will stay lite up by using the battery (that you where charging) power.

Good morning. I own this portable charger and love it. We live at 7400 ft in the Sierra Nevada. This charger is my second device and in answer to yourquestion, it will hold a solid charge for about two months. I check mine if weather is coming and the recharge is vey rapid. I have a special needs child and light is important when the power is down. It is a blessing to have for outsoor or indoor use. Hope this helps. Mrs Wetterer

While technically any battery could leak I have never had this happen to these high quality "eneloop" batteries. Keep in mind it is not so much the battery being left in the device as it is where the device itself is left dormant. If there are frequent temperature and humidity changes the device terminals are likely to corrode which could then damage the battery. As with even mechanical devices (such as springs) it is cycling count that eventually takes its toll. There is a lot of technical data available on long term storage and recharging. From what I know you want to allow them to store partially drained, but NOT "dead" as you can get polarity reversals. Also, it is worth the investment on a "smart charger" that will not overheat the battery and will automatically put the battery through beneficial "cycles" to improve performance and life. Also, it is worth monitoring voltages on all your good batteries... remember the pack is degraded by the weakest battery. In summary, store cool partially drained, smart-charge and never let them overheat.

For a definitive answer I suggest contacting B & D directly via the internet. I personally would not leave the battery in the charger for extended periods because it does get warm and I am not sure if it would/could get hot enough to cause any problem over time. Heat is generally not a good thing for battery life. When charging is complete I put the battery back in its box with the protective cover over the terminals. It usually takes about a week of use to drain a battery and then I replace it with the charged unit from the box and charge the drained unit starting the cycle over again. I don't notice any loss of charge from the charged battery sitting for a week. My weekly usage is blowing leaves, pine needles and sweet gum balls off of 2 porches, a deck and 2 vehicles + cleaning the floor of a 2 car garage.

No. I would say that since it is vented to allow heat to escape, it is not protected from the effects of sea salt in the air or humidity. I am almost positive you will not find any charger that offer's this kind of protection because they need to be open for heat disipation. It is however, a very durable and dependable charger you will get many years of use from if used properly

I would say not for long-term use. If you wanted to plug it in outside while you were there then yes but not for the direct sun or weather /rain

I've left it plugged in from November to April for two years at my cabin in the mountains. Haven't experienced any problems. Works great.
