how many hours does it take to go into maint mode
166681
That is a good question. I've never let my battery go completely discharged. I try to start up my bike at least once a month during the winter. All that said, from a 75% charge to maint mode takes about an hour or so and from 95% about 20 minutes. I have little confidence in the %age numbers anyway, as other reviewers have reported large variations with little or no logical explanation. Hope this helps.

If the battery is 85% charged it only takes 2 to 3 hours to go into maintaining mode.

My large car battery was at 78% and it only took 1 and half hours for me. And it has been very good at keeping it charged.Definitely buy it. Joe M.

When you attach the maintainer to the battery it will display a digital read out of the percent of charge that the battery has. It will continue to increase the percentage as the battery charges, when at a 100% it will display " fully charged and maintaining". It don't take very long to bring a battery up to full charge, but of course it depends on the condition of the battery. I would definitely recommend the charger/maintainer.

The SP3 is NOT to be used to charge a 12 volt car battery, as Schumacher considers a 12 volt car battery to be large. The Sp3 is to be used to MAINTAIN a 12 volt car battery, that is ALREADY FULLY CHARGED. A Schumacher tech also stated that it IS permissible to leave the SP3 connected to charge the battery, only if the SP3 initially analyzes your battery at 90% or more charged. Any initial readout, lower than 90%, requires you to charge a car battery at a 6 amp rate, with another charger, till fully charged, and only then attach the SP3.

This depends on how low your battery is. My motorcycle battery took 3 hours after sitting for 3 months and I bought the battery in 2006. My car batteries go maintenance within an hour. My tractor batteries take about 45 minutes.

Depends on the starting point of the battery. If close to fully-charged (> 90%), it's a matter of hours. If badly depleted (<70%), days. BTW, in the latter case you would be well advised to use a charger before the "extender".... I can't prove it, but my battery was replaced under warranty after I hooked up the Schumacher to a < 70% charged battery. Eventually it went to maintenance mode as if everything was okay, but the battery could npot hold a full charge thereafter. If true, that's horrible behavior from a "smart" product!

Hi, it should not take too long at all. Maybe 5 to 10 minutes, depending on your computer and the speed of your server. Jerry

I'd say around 30 minutes, it goes a bit quicker for me than even the manual says.

3-4 hours but I think it depends on your computer settings. I like a bright screen so I think I get less time.

I am getting around 4-5 hours depending on tasks I am doing. General web browsing and email is closer to 5 hours. If doing software development/testing closer to 4-4.5.

Depends on the definition of normal operation. I would say 6-8 hours if I'm just writing papers for school and 4-6 hours if I am writing papers and using wireless internet. Less then 4 if I'm playing games.

Highest setting you can expect 36-48 hours of continuous run time, lowest setting 86-94 hours.

I think 24 hrs would be a bit long. I have run mine for 16 hrs with some recipes.

99 hours and 99 minutes-not that anyone would ever need to. Just push in the time you want and press start. Simple.

I don't use mine anymore because it constantly trips the dedicated breaker. However, I just plugged it in (as it sits in the corner) and you press clock which defaults to 24 hour, press clock again and it will be in the 12 hour mode. From there, enter the current time and you should be good to go. Regards

If you're online, about 2 hours. If you're offline (i.e Office) somewhere between 4-5.

It depends on how much it needs to get back up to 100%. I wasn't really timing it, because I was busy doing other things. One reviewer said about 15 minutes, and thatmay be about right.

It depends how your laptop is set up and what apps are running. It''s about 55 minutes max doing text editing and web browsing under Linux. If you're running Windows, it would be a lot shorter time ~40 mins.

i think just a couple hours. maybe less. i think this is an excellent product and a great value.

depends on what you're doing. when playing a game, it will be dead in about 1 to 1 1/2 hour. Doing typical stuff, it is good for around 4.5 to 5 hours.

Less than 10 secs. It take longer for you to get peripheral devices up and running.

At least 8 hours, somewhere in the range of 8-12 hours in total. I have never timed it, so that is my guess.
