Problem when charging my Samsung Repp

When a mobile is fully charged the mobile tells you that it is fully charged and to unplug the charger. This is the firmware design.

It must be a battery problem as the battery indicator level says full when you remove it from the charger and the phone doesnt work.

Take the batteries down to a battery shop and have them load tested. Make absolutely sure they are DEEP CYCLE batteries. My 35a\h batteries put out 480 cranking amps. The battery shop can also test your charger. I have two chargers for my scooter the 4amp charger that came built into the chair, and a really nice three stage 5amp external charger. My scooters batteries have two 50amp quick disconnect connectors. I made up an external harness for the 5amp charger with the same connectors. I can now charge up my batteries out of the scooter. They say my built in charger is a 4amp charger, its slow in comparison to the 5amp charger. Batteries are expensive, regular chargers charge at one rate, full speed and can overcharge a battery. A three stage charger is by far way batter on your batteries. When you start to charge a depleted battery it put out full 5amps but as the battery nears being charged the charger backs off the amperage. When the battery is fully charged the charger goes into float mode and put out just enough amperage to maintain the charge. When i'm not using my scooter i keep the batteries connected to this charger. Deep cycle glass mat batteries don't stay charged very long when just sitting around. In about six months a dead battery will sulfate to the point where it will no longer take a charge. That happened to me once and cost me $200, never again will this happen to me. Battery shops are great places they have the instruments to tell you everything you need to know about the batteries. The batteries are the heart of your scooter unless you know there condition all kinds of strange things can happen. To make sure my batteries were good i have them checked against a known good set of batteries. BTW- Cranking amp is measured by putting a load on battery and increasing that load until the voltage falls off. At the point just before that voltage drop they measure the amperage output, that is you're cranking amps

Hi,

You just need to set black & decker charger to 12V . Don't make mistake while connecting + / - leads. + lead usually come with Red color cable. You can use the AVO tester to justify the lead cable. The charging time is normally about 10 -12 hours (or just just check the status on your charger display). If your charger does not has trickle charge facility, you have to disconnect your charger after 12 hours continuous use.

Also, you can find the guidance about your charger here :

when its fully charged, it goes off.

The battery is 12 volts and to charge use a 2-10 amp charger.

The gauge reads the amps that the charger is putting out. So 100 would mean the battery is dead and 0 means it's fully charged.

then there is a problem wit your charger and i suggest you go to the store where yiour service is
(i.e. verizon or tmobile) and tell them wat is going on b4 you go out and buy another charger

hi, I suggust you leave the scooter on charge all night.

The Charger should display a green light once fully charged, if this is not happening I suggust you first try another charger ,

Check the connections to the batteries, if the charger cannot sense the batteries then it will not charge if you have tried anther charger and it still not getting fully charged, the batteries will need replacing.
