How do i charge the battery? also will it hurt

NO, unless the battery charger is a "tender" type...(its not).... I would NOT leave it on charge, it will shorten the life!

The basic rule of charging is "charge for 3 hours for every hour of use".

You won't hurt anything if you charge it overnight, but don't leave it charging for more then 24 hours.

If you wear the battery out eventually, Batteries Plus can re-pack the battery.

The newer batteries charge up in about 1 hour. But being a new battery and first charge, don't be afraid to let it go a while, It won't hurt it and the charger will trickle down when it is full. You can leave them in all night if you want. I have one on the bench charging all the time, it is ready when I need it.

Leaving the camera on the charger will not hurt the battery. The type of battery you have will only charge till full and then stop charging.

I have used alot of battery type drills and other action tools . Ryobi is on the lower end of the market as opposed to Milwaulkee and Dewalt . But my experience with battery operated tool charging equipment is that if the light is green and it's blinking , I would say it's charging . When the light goes off or stays on . I would say it's charged . Leaving the battery or batteries in the charging unit for 24 hours will not hurt the battery . My solution here is put it in the charger , and check it 12 hours later !

Ashley you can leave it on or turn it off leaving it on will not hurt the scooter Hope this helps you

Mike ultimately it depends on the charging board and battery combination most modern units it won't hurt at all. I leave mine plugged almost all the time as well as my laptop.

Some DVD players will work without the battery plugged in anyway, and batteries store best with a partial charge.

I'm not going to get into battery science but Lithium Ion, NiCad and NmH batteries all like to be treated a little differently.

I think you are safe....but in time all batteries will fail regardless.

Cheers!

Get yourself a very inexpensive trickle charger that you can leave hooked up all the time. Itr will charge as needed, then cut itself off until the amp rate drops enough to warrant charging more. It will not overcharge, so you can leave it on all the time.

here is your manual in PDF form

if the unit was new then you would charge it for about 10 hours .. but since its not likely new then it doesnt hurt anything to just leave it on charge ... you can even operate the palm while its charging .. over night charge should be enough to get pretty close to full ... the palm internally automatically turns off the charge when the battery is full .. so you dont have to worry about over charging .. if the unit wont come on then you can do a "reset" (back at top)

actually it hurts every battery even your lap top's
