Can this charge completely dead batteries? I have a La Cross charger and when batteries get so low it won't charge. Will this charge from 0?

I know what you mean. The La Crosse chargers (BC-700, 1000, etc) all have problem detecting over-discharged batteries with terminal voltage below 0.5V. The BQ-CC17, however, has no such limitation. I have tested batteries with nearly 0V left, and the BQ-CC17 can still detect it and charge it up.

Yes from my experience it can. I always wait for my batteries to die completely before I charge.

Sure thing Hoppy-Doodle! I even called technical support at DeWalt earlier today (around 2:45pm CST) and they told me that it will work and will actually fully charge all batteries from 7.2 volts - 18 volts in an hour or less. I can tell you from charging my 9.6 volt batteries that it's amazing how fast I can fully charge both of my batteries and be ready to use them again. So the answer to your question is YES, YES, YES, YES, YES, YES!!!!!!!!

I guess you have to define completely dead. Will it charge a battery that has been completely drained overnight by leaving an accessory on? Yes, matter of fact it has a automatic De-calcify mode that helps make batteries last longer. Will it charge an 8 year old battery that died because of below zero temps? no, no battery charger will.

I have a La-Crosse BC-1000 which I have used to it's fullest potential. It's a very intelligent and powerful charger allowing you to charge at different amperages (higher for quicker re-charge and lower for a better recharge) as well as being able to completely de-charge to eliminate battery memory issues that don't allow a full charge. You can charge AA's and AAA's at the same time and each of the 4 positions is independent of the other. In other words, when one cell is charged, it will discontinue charging the fully charged one and continue charging with the rest and so on. There a little spendy, but to get the most out of your batteries for years of use, it's a great charger.

I read that these batteries, if not used frequently used, tend to go dormant and the chargers will not charge. Need to connect battery to a regular battery charger to re-energize. Recommend you try to charge another battery or investigate the dormant battery issue for your specific equipment. Hope this helps.

Yes, that is normal. This charger gives a deep slow charge that just takes time. It will bring a dead battery back to life if the battery does not have a dead cell. I recommend it as a good deep cycle charger.

No. It will not charge a dead battery. It will keep a charged battery topped off. I purchased mine for a vehicle we rarely dunce that kept killing batteries. After installing this solar charger, the battery has never died again.

I have a problem, that might be related and I wanted to ask people as well. When I put the battery in the charger (I have two), most of the time, even though the battery is empty, the charger shows green light and does not charge. I have to put the battery in slightly elevated angle and push on it and then it will start charging. So maybe your batteries were not charged at first place. Also happens to me, that the batteries discharge if not in use for 2-3 days, so before use I always recharge.

By pressing that red button, you can completely discharge the batteries before charging them. If you don't press the button it will the charge batteries from whatever percentage of charge they have to full charge!

No do not charge standard batteries with this charger! I would recommend the La Crosse Technology B-700. Fantastic charger!

I had this happen to me. Battery charger did not produce a charge of the battery. I got a new charger and everything works fine. I don't know how you would easily ascertain if the charger is bad except to see that the battery is not charged.

Smart chargers need to sense voltage to start charging. Get a battery that is fully charged and hold a small wire to each end of it with your fingers. Now put the "dead" battery in the charger and touch the ends of the wire to it from the good battery. The unit will sense power and start charging the battery you thought was dead. This happens if you let them sit dead too long but the batteries are usually still good.

Completely dead? If it is broken (dead) no, ... otherwise if the battery is completely depleted it will work. This has happened to me a few times. It also recharges very rapidly, ... about 2 hours for a full charge.

I can give you my limited experience with chargers. My previous charger destroyed my batteries because I didn't take them out when they were through charging. Maybe my mistake, but who wants to be stuck waiting for the charger to finish? I have used this charger quite a bit lately and love it!! I have AA and AAA batteries in many many devices around the house. I charge Eneloop batteries in this La Crosse and it has functioned perfectly. Yes, I spent a lot of money on batteries and this charger. Has it been worth it to me? YES.

Only if there is a residual charge in the batteries first. Suggestion, break the new batteries in 12V units and use a automotive battery charger to charge any pair that lacks any voltage. The reconnect all batteries and install this trickle charger. It should fully charge the batteries then...

This unit alone will not charge batteries, but you can find usb aa/aaa chargers all over that you can plug into the usb port of this unit to charge. I recommend the eneloop series batteries. They are great.
