My ds cant charge i put my charger in it never charged it is always red what could do

Try another charger, yours may be faulty. Alternatively,the battery may need replacing as it is no longer holding charge, these can be obtained very inexpensively from Ebay and you will just need a small cross head screwdriver to remove the cover on the back of the DS lite, then tap the unit in your hand to dislodge and remove the battery.

Sounds like your ds is in a sorry state. Unfortunately the DS is very delicate when it comes to fluids and if anything has been spilt inside it you have more than likely blown some circuitry on the motherboard. Usually the only way to fix this is to buy a motherboard or buy a new DS.

Well basically you cant charge it without a power input source so you gotta buy a new one or buy a power replacment kit on amazon or ebay

I would say leave it charging for 5 hours tops! if it's still red something is wrong with your DS!

Your DS is either fully charged or the battery got damaged/wet. When you play the DS, is the light red or flash red? If it does, then the problem is with your battery. http://www.nintendo.com/consumer/repair/dslite_repair_home.jsp
Click on your country, then "System and Game Problems," then "Power and Battery Charging Problems."
Hope this helped.

Did you attatchthe charge cord into the back of the Ds and attatch it to the wall? If you did and it didnt work, then I suggest getting it looked at, as this is usually the less expensive way of fixing it.

wiggle the charger gently backwards and forwards. Make sure you are using the right slot and the right wire. There is a big one for the DS, and a smaller one for the DS Lite.

um.... im jut asking dose it flash green, orange or red? if it flashes green it is fine if it flashes orange its giving you a warning then if it flashes red that is when you charge it oui? but if it flashes red and you still cant charge it well i ont know what to tell you? oui, no, maybe? wll if i didn help sorry but i tried. sorry or your welcome which ever best fis your dicription. †

When you first get the DS it will have a bit if charge on it but only a few hours worth. When the DS charges it usally comes up with a orange/red ish light then that goes out about a few hours later when its charged. ad if you want to chek if it is charging correcly turn the DS on whilst it is charging and the little battery simble in the top right corner should show the battery carging.

When I hooked up my DS with the charger the orange light would flicker for only a few seconds then turn off.

I found out that if you KEEP THE DS ON WHILE HOOKED UP the DS will charge. Although, because you are playing/DS is on the charging will go extremely slowly.

Best option, and what I did, was was just return/exchange it. I just did that today.
