How will i know if the batt. is fully charge - Samsung Cell Phones

Sounds like one or both of the batteries has a high internal resistance. Bad batteries, perhaps? Have you LOAD tested or tested for internal resistance? Could be why charger is shutting off so soon.
Voltage isn't the only test for these types of batteries.

How do you know that batteries are fully charged? If it won't power up then the indicator won't tell you their level. Pull both batteries. Push the power button (using what minimal power is left anywhere in the system.) Plug the camera into the external power source (mine has a base that will charge your battery, and supplies a cord for power to the camera.). If it still doesn't power up with the external power source, then I would say there's something wrong, but I'm betting it's the battery/batteries.

Vpad 7 frost at first n then now wont turn on? I need help to turn it on? Dont know whats goin on?

No, it should immediately start if you have the battery connected properly. Are you sure this new battery is fully charged? It may just need charging. If the battery is fully charged and connected tightly then you have another problem.

ur new batt probly was not charged -the alternator/regulator is failin -inspec whole electrical system for bad wires,contacts etc--things wear with age--library in 629 has many repair guides

how long do you usually charged the batt? to make charge last slightly longer leave the batt inside the charger for an hour after the charger light goes off. if you have a fully charged batt you should be able to take approx. 300 pics or 2.5hrs approx.batt life. for viewing pics it should give you approx. 6800 pics and approx. 5.5 hrs. of course, number of still images and and batt life may vary depending on the camera settings.so if you're zooming in and out,using the flash,going from camera to play mode, turning cam on and off, using other settings and features of the camera, this will cause the batt to drain much faster.also ambient temperature also affects batt life.if it's very cold, the batt drains a bit faster.also, it's recommended that if you're not using the camera to remove the batt.retaining the camera settings, date & time will cause batt to drain even if your not using it. if did this and still you think it's odd that your batt drains quickly and looses charge even if it's fully charge, it might also indicate that what you might be a defective batt. one way to find out is to try using the same type of batt from a friend or a relative that has one to confirm and further isolate issue.anyway, supplied accessories has the same warranty that applies to your camera.so you may send it out and have it replaced if needed.hope this helps.thanks:)

no if you have a good batt you don't need alt the alt charges batt after you start the car

Make sure all connections at alternator are attached. On some, the regulator is inside the computer and if bad, requires computer change.

discharge your batt. fully. charge your batt. on 3phase current. dont remove in middle, give time for your batt. to charge fully
