Can I set it to turn off after 14 hours and NOT come back on? I need to charge a 12Volt Batter and I don't want to overcharge it.

No. This timer repeats it's cycle every 24 hours. Each hour is devided into 4 - 15 minute segments, and each segment may be programmed to be on or off.
1840393
No, align the pointer to the current time and push down the segments or pins for the required time that you want it on. in your case that's 14 hours, after 14 hours it will be off for 10 hours. you will then have to manually unplug your batter within that time or it will turn back on.

It appears to be a continuous 24 timer. You can turn in on for 14 and off for 10, but then it will go back on again.

Sounds like you're looking for a "countdown timer" which has a spring loaded dial you would twist to the time you want it to stay on for. This constantly repeats a cycle for how it's set.

Depending on how much time you use up while in use. I think the charge is set for 45 minutes when fully charged. If you read the instructions it will tell you to let it run down now and then to keep the battery in good shape. I sent my sister-in law one of these and she uses hers and lets it set off the charger for a few day's after a short use. So, depending how long a time you use it each time is my answer. I enjoy mine very much and have had it about a year. Good Luck, Ruth Young

I emailed the company about this very issue. They said that was a feature on the prototype but was never programmed into the regular production models. I was told it will not turn off but that it should be fully charged in about 5-6 hours.

Overnight and then I leave it in the charger all the time except for when I'm using it. You can't overcharge it.

you cant shut it off, but all the times I have used mine, the battery depletes fairly evenly, never had one or more cells totally deplete while the others had a decent charge. I have only used it on 3 cell and 4 cell batteries. works great. are you using a balance charger for your batteries? that's all I can think of why your battery depletes so unusual. if not, get one that will also discharge your batteries properly for long term storage. you cant store them fully charged or drained.

If you want it off at specific times you can attach it to a cheap timer you can get in any harddware store for a few bucks. The reason you can do that with this unit is that i has an automatic power interruption/restoration restart feature. External timers are equivalent to power failure, and most brands stay off after interrupted power comes back - not this one. The timer built in selects short intervals for round clock on-off, which is not what you want.

I'm not a battery expert, but you should really stick to the charging voltage and initial current they show on the battery. Overcurrent will certainly warm it up and it may leak or explode on you, or just shorten it's life.

You can. You just disconnect the battery pack once it is fully charged, which by the way there is no indicator anywhere. The charging time depends on your charger/AC adaptor specifications. Connect the battery pack only when you are using it or charging it - that way the battery will last long.

My red indicator light never has gone off. I am not actually sure of this, but I simply leave the charger plugged in (AC mode) in the evening, then take it out of the charger next morning. I don't see any indication of overcharging or battery memory developing.

Your in luck as I happen to work for Stanley Black and Decker. If you started at 12.8VDC you already had a partial charge. 6 hours to top off the battery is a reasonable expectation. For a fully discharged unit (~12.2V) charging a minimum of 12 hours is recommended. This unit uses polymer lithium cells that dump their energy extrememly fast. Its the only reason this thing works at all. It is meant to assist a weak battery not jump a dead one!

the instructions say if a battery is left in the charger for more than 20 hours, the charger switches off power to that battery(s). But as others have saidthe best thing to do is remove the battery after the charging is complete.

Yes you can however you have to turn it off manually using the button on the bottom of the light. There is really no instructions with this product so you have to figure out everything on your own and you will see a button on the bottom of the light that turns it on and off. you have to leave it off to let it charge anyway for a day. you can then turn it on and off as you wish but you have to be able to reach the bottom of the light, it cannot be hung too far up in that case. it's the only way to use it like that.

Theres an app that does that. Just do it 3 hours before bed. Let it die. Plug it in turn it on charge over night then use regularly repeat 6 or 7 times a little bit of a hassle i know. But its worth it.

I might not have understood your question, in that you want the time a battery will last, once charged (hours)? Since I turn my computer off and on there is no way that I can tell how many hours I get on a complete charge, couldn't even guess.

Yes, you can set it for 14 hours. Just press the tabs down for when you want to timer to go on and off.

you could set up a timer on the power supply that is three volts to shut of then back on in 17 min timer this is a sealed computer box. So messing with that not advisable.

The instructions say "You cannot overcharge this unit using the AC charging method." However, elsewhere in the manual it says "overcharging will reduce battery life." But if you charge it DC you should not exceed 6 hours of charging time.
