Although it is not recommended for normal operation, try turning it on with the charger plugged in. If this works, check the battery status indicator. If it shows a full charge, try disconnecting the charger. If the Nextbook quits working, the battery is bad. If it does not turn on, try holding the power button for five seconds, then while holding the power button on, plug in the charger and continue holding for five seconds. If nothing happens, release and press the power button again with the charger still plugged in. (This may reset the internal power management chip.) Also, try the recessed reset switch (see your owner's manual). If none of this works, verify that the charger unit is good. The simplest and safest method is to measure the output voltage on the output plug with a digital multi-meter while the charger is plugged into an AC outlet. It should be within 5% of the nominal output voltage on the charger label. The most common power problems are battery failure, broken charger wire (usually next to the plug or the power conversion box), or broken charger jack in the unit.
Hello There are two possibilities for this fault. The first one is with its battery itself. If the battery did not hold current, in otherwords, it has weak, proper charge both in volts and amperes won't hold on it, and when the device draw current from it while it works, voltage drop will occur, and low voltage indication will be displayed. The second chance is due to the charger circuit inside the radio. If charger circuit do not give proper voltage and current to battery, the battery won't charge to its full capacity. Check it by replacing it with a new battery [batteries] first. If it helps you it's OK. If not, your radio need service, and its charger circuit must be checked well. OK.
if it will not hold a charge - then I would say that the battery is weak,old and bad and needs to be replaced. there is also a chance that the charger ityself is not putting out enough voltage to totally charge the battery. use a volt meter to check the charger and see if it is putting out the correct voltage,, if it is at the right voltage - then replace the battery.
Are the batteries really gettin a full charge or is your charger faulty. If you can borrow a voltage meter you can see what your battery is putting out and check the charger (plugged in) to test how much voltage it is putting out. If the Razor is 12 volt you can hook up a car/motorcycle charger to pump up those batteries. I don't think your batts are not holding a charge, i think they're not gettin a charge....good luck to you...Tim
if you have a meter and you are able to test do the following.
remove the battery from a set, and test the current before and after charging.this test is to confirm if a battery is able to hold charge. if they will be no differance change a battery.
battery contacts are suppose to be checked
regulators, if not leaking to ground.
charger voltage with meter.
You are charging. The meter corresponds to the level of charge in the battery. Try setting to 10 A for 4 hours, battery should be half-way up. To determine if battery id dead.. leave battery off charger once it is fully charged...test with a voltmeter after 10 min.....battery should still be above 12v...after1 hour it should still be above 12v...if not battery is spent.
It is impossible to overcharge with the Pride charger. When the battery is full, it will stop charging and check about oncew a miute to maintain the charge.
Now, when you plug in the key (looks like an audio headset jack) does the battery meter indicate a full charge? Also, the scooter will not move if its in free wheel mode, and it will not move if the charger is plugged in. Beyond these first steps, you will need a voltage meter to troubleshoot.
1 Is the charger unit OK? Connect a voltmeter to the camera plug to test the voltage. While connected, wiggle the wire at both ends to test if it is broken. If not OK, replace charger unit.
2 Is the battery OK? Test battery voltage with voltmeter. Connect crocodile clip leads to the voltmeter probes and a good charger. (A cut paperclip can be inserted into the center connection of the charger.) Check that meter reading is positive, and then hold meter probes on the battery terminals, making sure polarity is correct! Voltage should drop immediately, and then start to slowly but steadily rise after after a few seconds. No change with a flat battery indicates battery failure. Replace battery.
3. If both charger and battery are good, then problem is with camera. There are no user serviceable parts inside the camera, and as with laptop computers, it will probably be more economical to buy a new product, and take advantage of the always cheaper prices of newer and better models.
First off Charging the capacitor can put you holding a high power voltage source. This can be very dangerous. It is enough to kill you. I suggest for safety go ahead and mount the capacitor in its location. The easy way to charge a capacitor is using a 12 volt Battery Charger. Hook the charger up to the capacitor just like it is a battery. + to + and - to - ... Charge the capacitor until the charger meter falls to near zero amps or indictates full charge. No need to use a light bulb or anything. The Charger comes with it own limiting circuitry. I will be posting the wiring instruction shortly.
