Why is it that it takes around 12 hrs for my laser mp4 to fully charge?

Depends on the battery... a "toy" battery may only need an hour or two....a motorcycle battery may need 12 hrs @ 4 - 6 amps - depending on the type of battery....a car battery may need 10 amps for a short time (4 hrs) because they come pre-filled and charged. I NEVER depend on the "charge" of a new automotive battery (of any type)..I always charge them for at least 4 hrs @ 10 amps before initial use!! ...they seem to last longer

BUT - AS a RULE = 10 hrs @ 10% of the rated amperage...

Dear
the battery is fully exhausted. Pl. do charge 2-3 hrs. in its condition and then power ON to check. It takes approx.4-6 hrs. to charge.
Thanks.

Have you fully charged the battery? if it is a new camera or battery,it needs at least 12 hrs of charge,to maintain good charge, if only a short time of charge was given from new the life of the battery will be greatly re-juiced,try a new battery with a full charge, if this fails your camera is probably faulty, take it back to get a replacement.

there is battery indicator in every chargable instrument. try to find that indicator in your media player. initially it should not take more then 24 hrs to charge the battery fully. if the battery indicator does not blink it seems that battery is fully charged. remove charging & observe how long it works.

i think in 3 possible solutions: 1- try to charge it with another charger 2- connect your mp4 to a computer and run a virus scan, after this try it. if don't, format your mp4 and try to charge it again. 3- the charge system of your mp4 is damaged, so take it to the technical support for to repair it.

Garmin satnavs come with a charge out of the box. In most instances you will not need to charge before using. Your device will charge while attached to your 12V vehicle power cable.
In some cases your device may have lost a charge during shelf life. In this case you can charge these units in three ways:

1. Place unit on computer with USB cable for approximately 8-12 hours
2. Place unit on Garmin specified AC adaptor for approximately 4-6 hours
3. Place unit on 12V vehicle adaptor for approximately 4-6 hours

Your device should be fully charged after applying one of the steps from above.

depending on the type of battery and charger the time usually takes from 6 to 12 hrs. for a full charge. Shorter charging time will result in battery not operating to its full potential

Is it new and you are trying to charge for the first time?

First time charges can take up to 12-24 hrs. depending on the device.

at a minimum your batteries need to be charged for 12 hrs a day for the first month if not they will not build the capacity and will dwindle and die for example it is at only 25% capacity it says it fully charged but will die quickly this happens because it is charged to its full capacity but that is only 25% of the batteries true potential resulting in short battery life
