Red lights on charged but wont go on charger and battery are new

Mine is an Invacare M51 Pronto Surestep with an onboard Winsunny battery charger. My charging lights are solid red and green/ yellow. Depending on if it is charging or not. What kind of charger do you have?
I have to replace my charger because it is not working. My green light is staying green while charging even though my joystick is showing my batteries are depleting and I just got new batteries. sigh.

make sure battery cables are secure at battery terminals and clean.how old are the batteries.If the batteries run down fast they are no good.a good way to test them is put scooter against some thing solid and go forward.If the battery indicator drops to o the batteries are no good.It takes about 10 hours to charge the batteries

MStrong The charger will not charge batteries that are reading that low Replace the batteries and try the charger again. Remember to always charge before use and never charge longer than 12-16 hours. Get into the habit of charging overnite on scooters used everyday and once a week on seldomly used scooters always sore the scooter fully charged and if storing for a longer time remove the batteries and store fully charged. ope this helps you

Return to store for replacement.

new battery flashing red light means bad battery

did you try the car charger,wall charger might be faulty,if that does'nt pan out,might need new battery

Before getting a new battery, make sure your charger isn't the thing that's broken. To do this, borrow a charger that works good from a friend and try charging your DS. If it doesn't work, than get a new battery.

Hi I am Vortah The red light is usually an indicator that the battery is charged however in this instance as you are saying it isn't the battery has possibly gone short and you will need to replace the batteries . They have a type of internal memory and only charge a certain amount of times before they no longer accept charge and merely overheat during charging .. But I have to say it may be possible the charger is faulty as if the internal rectifier that charges the battery has gone short that may also bring the red light on in some chargers .. so try the battery or as I would do take it along to your nearest dealers and get them to check it . it may save you money in the long run you could be buying a battery you still cant use when you actually need a charger .. Hope this helps regards Vortash

It's a known Fault with the NP-20 battery don't order one and pay for it, ring or e-mail casio customer service they should send you one out for free!! When you receive the new one don't let it die, make sure and keep it partially charged at all time or the charger won't recognize it. Really casio should recall this battery but for some reason they insist on replacing faulty batteries with more faulty batteries!??!

Could be battery or charger. 1. Buy new battery. Still in trouble? 2. Get new charger Its good to have two batteries
