Will this unit charge batteries that are ran completely down. The orina charger will not work unless the batteries are charged to around 45v

this battery charger would only charge just a little bit, and if the batteries were completely dead, it wouldn't do anything at all...eventually it got so bad this charger wouldn't work at all. One of the worst purchases I've made in a while...take my advice, spend the money and purchase a dedicated charger for your golf cart, it's worth it!

you can charger the low batteries one at a time until you get about 25 to30 volts. then hook up your charger to test it out.

It probably depends on how bad they are run down. However, I recently used it to individually recharge 6 volt golf cart batteries that were down to 1 volt.

Yes it does work at full rated amps but only for very short periods. It constantly cycles out of the higher amperage because the unit cannot handle hard charges. It is OK if you are charging one battery over night or for more that 4-6 hours and need the surge to kick out a start, but it is a light duty charger. Do not expect it to charge a battery bank of 2 or more batteries.

I don't know but I've learned if charger says bad battery & shuts off if you can put a little charge in with an older charger, this charger will then take over & gradually bring that battery back from the dead. my charger model is 12 v only and relatively low camps, but it has restored several batteries for me if given the time to work.

Apparently not. There is a statement on the charger that states "For 18v B&D; batteries only. Other batteries may explode." I am not using the charger since it will only partially charge the batteries.

Should work. Mine does. Can you check amps from unit charger on battery with amp meter? Try again, recharge unit, clamps with good connection and try on dead battery and measure amps. If bad return to Amazon. Good luck

Without knowing the state of your battery it would be hard to say. Try the recondition button to see if you can get the battery to work, press the large button until recond light is lit. It takes a while to recondition the battery. Modern battery chargers will not charge bad batteries. If you started with a dead battery, then recondition may help. If the battery was okay then you have a bad unit. I would try it on a good battery before sending it back

I learned that sometimes running a discharge cycle first then let the charger do it's job works really well but if the batteries are there for hours, there most be something wrong, are the batteries new or are they over a year old? Some old batteries will never charge. There's a chance also that the charger may be defective.

All 4 of my chargers are set for 4.2v.I have had NO problems at that setting But, always charge new batteries as soon as you get them.I charge all my batteries, any size in it.The charger is automatic , stops charging at the correct voltage.George

The charger is identifying whether the batteries are appropriate. It should begin charging in a steady light if the batteries are deemed appropriate. It will not charge just any battery.

it will charge other batteries but is very poor at it. Slow to charge other brands and charge doesn't last

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.

Hello: I'm guessing you have the 18 volt unit in which case a 19.2 volt will not work. It is very important with these types of batteries not to overcharge by leaving battery in charger longer than instruction manual states. May also be charger problem.

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.

It would ruin your 36 volt batteries by overcharging them .go toSave A Battery 2365-36 36-Volt Battery Charger and Maintainer

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

I would say yes. This charger allows you to leave the batteries on the charger so they have a full charge when you put them in.

I disassembled an old unit that failed to charge after a year or so and removed the batteries. They would not charge with a "hobby" charger designed for electric RC cars and such. I then discovered that storing the unit in the charger when it is plugged in was overcharging the batteries. I have another unit about 4-5 years old that is still going strong. I charge the batteries overnight when they will no longer last a full brushing cycle. NiCad and NiMH batteries have a very limited life when charged to 100% capacity repeatedly.
