How do I know if ps120 battery is no good or is it the charger unit

Mine was good. It was not initially charged but it charged up fine and it holds a charge OK so I didn't have to buy a new drill. If yours will not hold a charge, then that is a problem.

My charger melted the battery I bought from Amazon. Ruined my drill, so don't buy from Amazon. But to answer your question I would say the battery is bad.

Hi: I had that same question. So I just bought the battery thinking that would solve the problem. But it didn't. So I ended up buying the charger and that just prolonged things. MY advice, purchase BOTH at the same time and be done with it. JOHN

I am no expert but it sounds like low battery power. I found one of my batteries no longer holds a charge even though the charger indicates it is charged. Otherwise check to see if the shaft is not fouled with dust or hair etc. Could be that also. Sorry, best I can do.

Never had that problem. Try to use the battery and see how long it will last then you'll know if the charger is working properly, and if the batteries are fully charged or not.

I have played the unit for a good two hours with the battery. I almost always have it plugged in when I view it. I would see about returning the battery, or getting a new unit. Thats what I like about Amazon, I have never had a problem with a return or replacement.

Make sure that you bought the right battery first. Look up what kind of laptop you have usually it is printed on the laptop somewhere. Mine is a toshiba satellite. Then google what kind of battery it takes. Make sure that the battery is properly installed and locked in place(tabs near battery) and that it doesn't wiggle. Next is the charging unit. Make sure that its fully put together and connected to your pc power slot. If the battery is right and the power charging unit is fully conected and still no charge check to see if there is an orange light when you plug in the charger. If there is your prolly have a defective battery and should return it, if not then you prolly need a new charger or internal charger connector(pc end).

Sounds as though the charger transformer may be shot, test it with a tester or hold it to your ear see if it buzzes, or feel it see if it gets warm. Check connections also. Assuming of course it is the correct charger for the batteries.JT

I'd start with the battery. If the unit has not been used in a while, the battery probably has lost it's ability to be charged.

Would appear that either (1) the battery is no good, (2) the charger is no good, or (3) neither is good. Likely hood is that battery is defunct. If you have a Batteries Plus store near by (maybe a Radio Shack), they should be able to test the battery for you. I purchased a replacement battery on line. Same battery but much lower cost is available on line from different sources. But, you will likely need to cut the adapter plug from your existing battery and solder leads to the new battery.

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.

From what you describe, I would say that replacing the battery may very well solve your problem. Check the little battery style icon in the upper right corner of the display. If it shows red or possibly only a single green block after you have had it on the charger, then your battery is likely weak or failing. If it indicates that your battery is fully charged by displaying all green blocks, you may then have some other problem. Either way, a new battery is relatively inexpensive and would be well worth a try to fix your problem.

You are not pluging the charger in right or the battery went bad. Contact the store and have them send you a new battery.

I got a similar unit and when I first plugged it in, it too showed "fully charged". I then unplugged it and checked the battery level, but it instantly showed 0V. So that told me the "full charge" reading was false and the charger was giving me that reading while the battery seemed like an "open circuit" and was not accepting power yet. So I did leave it plugged in and within 1/2 hour it began dropping the reading to show 65% charged or such which I knew was more realistic. So despite getting that "full charge" reading off the bat, it does need the charge time.

don't count on any new battery to be fully charged! mine had a charge but I'm sure it was not 100% charged. Once installed your system should start charging it.

Are you sure the charger is working, I would check that first? If so, also suggest you might need to disassemble it to determine the battery model and type, then search online accordingly. Sorry - not a positive answer to your question.

Nope. This might be a knock off styled battery charger, or the batter itself might be broke. Do you have any other batteries to try out to see if it's the charger itself or the battery? Someone you can borrow from? Do some testing to pin down what it is that isn't working here. Good luck.

Check that the battery is 1) good, and 2) installed in the correct direction. If it does not turn on automatically when these are correct, then the unit may be faulty.

Put the battery on the charger ang charge it for a couple of hours. Put the battery back on the drill. If the drill runs faster that it used to be then the charger is working and the battery is about dead. If there is no noticeable difference in speed then the charger is bad.
