How long does it take to desulfate a battery? If you manually place charger in desulfation mode will it automatically go into charge when finished?

I have never used the manual setting, but have 5 of the chargers and just set them on the type of battery and leave them on permantly. The golf cart, motorcycles, etc. and have not had to replace a battery in over 4 years now. If I could find my manual, it might tell if it goes into the charge mode! Good Luck, Jim

Not sure about how long to desulfate, I think that would vary according to the amount of sulfation, but it has been pretty quick on the batteries I have done. Yes it does switch automatically to a "charge" mode thus making it a "set it and forget it" tool for overnight usage for instance.You can get more info at their website...

There is no need to worry about charging time. Just insert the battery into the charging station and when the battery is fully charged the chargingstops. There is no harm done by leaving the battery in the charging station indefinitely

If that battery was truly dead and maybe also sulfated, this isn't unreasonable. Remember this is both a charger (but not a very powerful one; 900 mA is 0.9 amps, so a typical car battery of about 200 amp-hours would take over 200 hours to be fully charged by this device) and a desulfator. That second process might also take a while.That said, if the battery's no longer able to take a charge, no charger will restore it.

I have a BatteryMinder 12248 as well as the 10030A. The Schumacher is junk in comparison. It basically uses a 15 volt charge to desulfate instead of high frequency voltage spikes. The higher voltage boils the battery and only runs when the charger thinks it's required, which is almost never. The BatteryMinder constantly desulfates, even in float mode. The 10030A is not temperature compensated during the charge phase, the 12248 is. I could go on, but you probably get the point. Get the 12248 BatteryMinder.

If I understand it correctly, it"s kind of like a "Miracle Charge" you would put on your motorcycle or antique car, but this one, "a microprocessor-controller that constantly monitors the RV battery status and automatically selects one of four charging modes: Boost Mode - (14.4) to quickly bring the battery to 90 percent of full charge, Normal Mode - (13.6) safely completes the charge, Storage Mode - (13.2), automatically activates after 30 hours of non-use or Desulfation Mode - (14.4), for 15 minutes every 21 hours to prevent battery stratification and sulfation (the leading cause of battery failure)." I think it monitors the batteries, locates the lo battery and re-routes power from another battery. It's not really a battery chargers, but more of a routing station. My RV has 5 batteries and sometime certain batteries use more power than others and this helps keep them all charged ith in the same range. That is what the hi-lighted section refers to. Mine has worked very well. Dont buy the cae they try to sell with it. Its plastic and will disappear with a good kick. I used a chain of a cable with a lock. I hope this helps, but I could be totalyy wrong.

I just got two of these batteries about how long does it take to charge them. Also do you use a standalone chargers.

The main thing is to avoid using a charger with a desulfation mode, which can destroy a lithium battery. From the BT documentation:"As long as the battery charger does not have a desulfation mode and the peak voltage does not exceed 14.8V during the charge cycle it, can be used to charge a Battery Tender® Lithium Battery."I use a trickle charger to take the battery to a full charge, then immediately disconnect. Because of the low self-discharge rate of a lithium battery, there is no need to leave a Lithium ion battery on a trickle charger for an extended period of time. full charge.

I got a similar unit recently and when I plugged it in, it too showed 100% charged. However, I unplugged the charger and checked the battery voltage which instantly dropped to under 6V. So that told me that the battery wasn't accepting a charge and the "100%" reading was coming from the charger just while plugged in. So I left it plugged in and after an hour it did start accepting a charge and the reading dropped to 60% or such. So it does take at least 12 hours, after that if it starts displaying 100% it probably is charged.

If the battery is really low, the minder won't bring it back. Charge with a regular charger and then put the minder on it so it can desulfate it. If this doesn't work, your battery is gone.

It really depends on the charger, but using the BCG34HRE4KN with the full cycle turned on usually takes 12 hours for me (this feature will completely drain the batteries before start charging).

No. It should take about double the time than the original battery. Are you using the original charger? Some chargers deliver very low current so it takes longer to charge.

Hi... It takes up to 30 minutes when I use the discharge/charge sequence. Amazing battery.

Quick answer is yes. It will take awhile though. Slow charge not rapid. Your looking at 4 to 5 days of charging If your battery is still good. Remember that batteries have a memory. If they are too low for too long they will remember that level and not do say the full 12 volts. Also other factors involved.

This is a charger/maintainer. Your batteries should easily hold their charge for a couple of weeks without power to the battery. Once power is restored to the MinnKota, it should bring batteries right back up to spec. Have had several chargers and this is by far the best and most effective. It even senses battery temperature and adjusts charge accordingly.

It seems to take about an hour (the charger turns off automatically) I usually leave it plugged in for an additional hour in case it needs to do any charger balancing.

It takes sometimes up to three short charge sessions to get a new battery up to snuff. Watch the temp of the battery case and if it gets warm-hot stop charging it and let it sit for a while. It needs to sit for at least an hour after you pour in the acid, tip the battery slightly to get all the bubbles out. Don't press down the battery seal (caps) until you get the battery to accept the initial charge(s). Then you should be good to go. Don't exceed 1 1/2 amps.

That depends on the battery. When I charge my lipo 2s 5000 mAH battery, its under an hour. Also, there is a quick charge feature if i;m not mistaken. There are reviews of this charger on youtube so you might want to check that out as well.
