My I river H10 won,t start after purchasing a new battery for it.The charge light on the charger is dim

CHARGE THE BATTERY WITH A CHARGER AND FIND OUT WHAT IS ON DRAINING THE BATTERY OVER NIGHT

stop leaving it plugged in all night it will over charge ur battery if doin so

Yes you can if it has removable top.If it is sealed then no. Have your battery load tested,it might not be any good

Hi,
Please, try using another charger with the phone.
If the problem continues, get a screw driver, unscrew the phone and bring the charging port out. The charging port is at the tail end of the phone.
Clean the surface of the panel where the charging port contact the panel with a spirit and allow it to dry for 30 minute. Couple back the phone and i am sure the charging phone will work fine.
Regards

If the phone was totally dead before it refused to charge initially, then the refusal to charge is due to the fact that there was no residual charge left to bring it to a charge, because the battery completely died.
To fix it, kick start the charging process.
Remove the battery, and using a universal charger (desktop charger) charge the battery for say 10 minutes, before re- inserting the battery to the phone and continuing with the normal charging process.
If this does not work out, then problem is with the charging port. It has to be replaced. This can be done by nearby local phone repairers.
Hope it helps?
Success.

1. Check all battery connections.
2. Load test the batteries, they may need replacing even if they are new
3. The charger has an inhibitor in it. That means if you don't have enough voltage going through it, it won't even turn on. We think that just because we plug it in it will work, not the case.
4. With a multimeter set on 200dc red lead to red terminal on one battery and black lead on the other. You should get a reading of at least 20 vlts dc. If no reading put the leads on the other terminals. Once you get the reading plug the charger in to see if the reading increases. If it does the charger is good. if not replace the charger. You will have to charge the batteries on a car charger to get them to 12 volts each.
5. If none of those work check the continuity of the front to rear harness. replace if you have a dead wire.
6.Lastly and most costly. your controller may be bad.

Good Luck

what have happened? did it just stop work or
have u done anything or dropt it? i need more information if i gonna try to help ;p

Well maybe your charger is faulty or when you used " alot of force " to push it in to the little hole it has to go in to charge it has moved it , if so then you will need a charger pack. but before you do anything try to get a new charger , Hope i helped :)
