how long will this hold a charge if not used?

The manufacturer suggest keeping the unit plugged in since it has an automatic charger that keeps the unit charged without overcharging. The other models they recommend charging immediately after use but do not provide a shelf life for the charge.

I have kept it in in my car in cold winter for 4 months without recharging and it still had full charge on it when I checked

If it doesn't stay charged at all, then it's defective. If it stays charged, but not as long as you think it should, it could be usage. I use mine walking my dog every night. Granted it's only 20 minutes at a time, but it seems to stay charged for about 5-7 days, using it once a day for 20 minutes. When my husband uses it on a project, I have to charge it more frequently.

I charged it over night to start. about 12 hours and it has never run dry. I charge it for as couple of hours after use to ensure it is charged for future use. there are time s that I don't use it for more than 30 days but it still stays charged.

Long enough that I forget when I last charged it. My guess is a minimum of a month with daily use, but as I said, I don't remember the last time I charged it.

Depends on how much is left in the battery. I just let it charge overnight, I have never timed the charge, but I would assume at least 4 hours from a full discharge.

I think it depends on how much you use it. The charge on mine goes for about a month.

I'll guess a few hours, if you use it a lot. I keep mine sitting in the charger all the time, though.

It only uses it's rechargable battery. Mine will keep a charge for about 5 to 6 hours.

IDK! I know that you have to check it to NOT charge (keep pressed the buttom to disable) to maintain the charge. But how many days... I really can't say. it suposed to hold it like 30 days or so. but never tried.

If you're using it once for a long time than Yes it will give you 30 odd minutes run time, but generally I use it for max 5 to 10 min at a time so the charge last for at least 3 to 4 times of use.

I would guess several hours, I didn't keep it in constantly after a charge, but using it 20-50 minutes at a time a few times a week, it lasted over a month for me.

I do not know how many days it holds a charge but I have had mine fully charged and unplugged for a month now and it is still fully charged as I checked it yesterday. Hope this helps.

No it will hold a charge for a couple of months. There is a check light that will light green if it's charged when you press the check button.

it lasts as long as you dont use it. the battery does not lose its charge once it is charged

If you charge it for 12 hours it will hold a charge for 3 months but its best to charge it every 3 month 2 to 3 hours . I hope I answered your question good luck .

It will hold the charge for weeks, but I don't know how many. The blue light will stay on for a while, but then it turns off if the unit is not used.

Not that long! If it's only working when plugged in, something is wrong. It also holds a charge for quite sometime. I can't remember the last time I charged mine (though I only use it sporadically).
