Will this charger work on non-pcb 26650 batteries?...How do you keep them from overcharging w/out a pcb on the battery?

The BMS (battery monitor system) is inside the charger, independent for each battery, so it works acceptable.During discharge there is no BMS, so they're relying on the application to handle that. I use these in LEDFlashlights, which the majority have undervoltage shutdown, although it's based on the string of batteries, so if you have two in series and one is fully charged and the other is discharged, you could have problems.If you fully charge the two batteries and put them in the flashlight at the same time, you shouldn't have any problems.

yes this charger should work with other batteries. the charger has an auto shut off when battery is charged.

Yes the 26650 batteries can be charged with it, that is what I use it for. As Jeff states, the charger shuts off when the batteries are charged. So far it has worked perfectly for me.

I haven't used any other battery and charger except for the foursevens 26650 and its single-bay charger also from foursevens. Make sure the battery has a built-in protection circuit, because even if the flashlight itself has a circuit to protect the LED, that doesnt stop the battery from being too drained or possibly becoming overcharged.

The charger must be bought separate and specific to the type of 26650 batteries tbey are a special size and almost the size of C batteries but they don't fit(alkaline C batteries

It will fit and CAN BUT, you should respect the maximum mfg recommended charge rate in milliamperes. Check the battery company mfg for charge milliampere. And yes it will charge four at the same time. The maximum this charger will output is:750 mA for 1.4 volt batts. And 500 mA for 4.2 MAX VOLT. Keep in mind if you own 26650 batts.it will only charge 2 total on the extreme left/right bays.

The 18650 charge fine with the 1000mah, and will charge two at that rate. I don't think the 26650 batteries will fit in this charger and I don't see them as being supported on the amazon page.

I tried to charge my 10440 batteries with the charger and it was not successful. It could be a failure on my part. However, I would buy a charger specifically for the 10440 batteries just to be certain of a proper charge. That's what I did. The charger still charges every other battery I have thrown at it.

Went to local thrift store and found a 24 volt dc charger for $3.00, you may have to change the plug to the battery pack to match connectors, works great!

Where I use this battery it has a build in charger. The one on amazon "Sealed Lead Acid Battery Charger UPG D1724" should work fine. It is only $8.29. http://www.amazon.com/Sealed-Battery-Charger-UPG-D1724/dp/B001G8AIMU/ref=pd_bxgy_p_img_z

Probably not, if it is a 3 pin connector the charger you are supposed to use probably is monitoring the temperature of the batteries while charging. If you are good with electronics you can probably get this to work by wiring in a connector, but it may decrease the life of the batteries and not charge them correctly.

This company folded a long time ago. Try EBay, flea markets or drill charger type charger I gave the specs here a while ago.

yes you must buy a type of charge controller that prevents your batteries from being over charged or over discharged. a pwm (pulse width modulation) is a good affordable choice for charge controllers. i think the one i bought was 60$

I have used several chargers and they have all worked with these batteries. You should not have to purchase a specific one.

I currently use this charger and it works fine.One caveat is that the controller(2002 Club) I have over timedegraded to cause the charger to not work. I ordered a secondcharger and when I received it had no output when hooked tothe cart. After some surfingand a call to the MFR I figured it was the cart controller sensingthe charge voltage and shutting off the charger. After I bypassed thecart controller so the charger fed the batteries directly all was fine.So now I have have two chargers........they work fine.By the way the MFR was very nice to discuss my issue withme and was very satisfied. Good luck. I currently use this charger and it works fine.One caveat is that the controller(2002 Club) I have over timedegraded to cause the charger to not work.

By that I guess you mean ones that this charger was not designed to work with right? Well, that is a little tricky based on what you are trying to charge. If it is a commercial battery for a drill, you can get something similar to this if you just type the drill's name or model. You don't have to worry about typing the specific battery model number or the specific charger model number and you will see a few results for just the charger mixed in with the results. I typed craftsman 19v and found this one. If you are trying to charge something else or another tool or battery by another manufacturer and you don't know exactly what you are doing, you are asking for trouble but I will give you a few tips. 1) Lithium ion batteries are ticking time bombs. They will explode if over charged with too much voltage or current. 2) LiPo will explode if wrong polarity is used. 3) Most of them have protections from the things that make them explode and some even have them per cell. Some of them though rely on the charger to be smart enough not to over charge and have odd terminals so you can't charge it in any other charger. 4) They all operate in series and some, like this one, even charge in series. Thus with a multimeter, find the polarity of the battery you want to charge and the approximate voltage (I.e. if you have a 24 volt battery and it has 4 terminals and per two terminals you find that they are 10 volts each when low on charge then one can assume that you have 2 sets of 12 volt batteries in a series) then just get some alligator clips and clip them to another power source or power adapter of the same voltage and then sawpt them between the series. One time I really needed a device and I forgot the charger and I did this by connecting the alligator clips to my car for 30 mins then I swapped them to the other terminals for 30 mins too and it got me out of trouble. Just be really careful not to overcharge. Hope this helps.

Yes... We have a number of the Max 20 Volt B&D; tools and a couple of different battery sizes... All work well with this charger... In fact, we have two of the chargers so that there are always a couple of fully charged batteries availble for jobs that involve more than one tool...

Sorry, I can't shed any light on the subject, Brian. After ordering the charger I discovered the problem was with my battery not the charger - I returned the charger I purchased through Amazon. My battery had run too low to be charged using any charger. I had to take it to a golf cart service store and they got it up and running for me. The charger I had was perfectly OK.

I cannot answer that question. I think from all I have read about this charger it cannot overcharge or undercharge its built into the charger. I use mine to charge my boat trolling motor and when the green light comes on I always disconnect it. I have never left mine on to continually charge. Some battery chargers will damage the battery if they don't switch to the maintenance cycle. But once again I think this battery charger it's all built in to not overcharge. That's why I bought it. Hope this helps some. I am just telling you how I use mine and I have never left mine hooked up past the full charge. Sorry.
