Meguiar's corded buffer??

[w77]

Here's what I did to my cordless buffer. Could someone comment on this because I'm probably doing it wrong.

I've been looking for a transformer with a minimum output of 3amp on at least 5 volts but they cost almost the same price of what I paid for the buffer. This is to connect my buffer direct to the mains because the battery's charge only lasts 5 minutes. While at Wilkinson today I saw this small 12V battery charger and it says (2.7 Adc equates to 4 Amp RMS) on the box. So decided to give it a try. Plugged the charger then connected it to the buffer and whola!!! it worked although I noticed that it's running faster than with it's fully charged battery. I think 4Amp is just right to run this motor.

The question is......Is the 12V power too much for the buffer's 5V motor. I tested it for 5 minutes and everything seemed to be working very well, no smoke, overheating or bad smell coming from the machine.

the wiring is just a temporary connection

No luck with Meguiar's then ?

I personally believe the answer is yes you are doing something wrong.

Surely the polisher is not performing the job it was designed to do, a five minute charge is quite simply a nonsense. By chucking 12 volts at the motor you run the very high risk of burning it out??

Good luck,

hi C43, thanks for your advice before. Tried what meguiars edviced me, charging then discharging it for many times and so far it has only gained from 2 minutes to 5 minutes. There's nothing wrong with the motor it's just the battery that doesn't hold its charge for long.

Lets just wait till I use it on my car.

The problem would be that a polisher is designed to run at low rpm - by increasing the voltage it will be running faster (only you can tell how much faster in this instance) and you run the risk of putting marks into the paintwork.

That's what they asked me to do,it did not work.
