I have an Invamed delux 4 wheel, its basically a SPRINTER XL4. it has done about 4 miles.i have fully charged it,according to the charge indicator all lights are fully red meaning it is fully charged up. i can go for 5 or 10 mins then the charge indicator goes down to 2 bars.plug it back in to the charger & that tells me it is charging,.....again.this has hardly been used. any advice welcome

Those chargers are designed to turn solid green when the batteries are fully charged. When batteries are less than new and have some time on them they will not charge as much as a new one. It is conceivable that either the battery condition is not the best there is or that perhaps there may be something wrong with the charger.

I suspect it is the new batteries not being so new.

hi , sorry to hear that , please contact me and i can advise you , i won't put info on here because this site is now asking me to fill-out a CAPTCHA every time i post something .,.

I hope you kept the old batteries, I would refer to where you purchased the batteries also take the charger you use for a test.

Is the high low speed switch turned to high. If it is and its still slow it would indicate a throttle pot fault

The motor is overheating. The service manual will tell you how to test. Pride has a service manual you can download from their website.

Yvonne,

When you say that you put in a new battery, I hope you mean new batteries. This particular scooter takes 2 batteries and just changing one will leave the remaining one in poor condition. Make sure that you have replaced the batteries with the correct size and type. This scooter takes 2, 40 amp hour batteries. Sealed gel AGM batteries are preferred. The batteries should have the number 40 on them with a date code. You need new, fresh batteries to have them work properly. A date code tag of A1 indicates the A month(1st month) or January of 2011 (1 is for 2011). If you are not sure of the battery condition a local shop can load test them for you.
There is a possibility with a 5 year old scooter that a worn motor/brake will cause excessive current draw and drain your batteries. A qualified technician can determine this for you with a service call.
Hope this helps.

w beck you have to remove the seat by pulling it out of of the seat post and then remove the shroud or cover by pulling it straight up You will then be able to see the batteries. Your scooter equires two 12 volt batteries probably U1 batteries Hope this helps

`Hi. Sounds very much like a loose battery terminal, or a faulty battery lead connector.
I have also had a few machines that can start jerking because of worn or stuck motor brushes.
Also check the high/low speed switch if you have one, they sometimes cause problems.
How old are your batteries, worn out batteries can still be " fully charged", but are unable to supply the current ( amps ), that the motor needs.
Good luck. Neil.

Hi. Sounds to me as if you have a sticky carbon brush in the motor. Each brushe is held in the motor by small black plastic or bakealite cap that screw in the outside or the brush holders. If these caps are not tight enough then the brush or the spring will arc from the side of the brush holder. This causes the brush to become jamed, and does not contact with the commutator on the armature.
You need to remove the brushes, check that they slide freely in the brush holders, fit new springs if neccessary, and reassemble. If the brushes are too tight, the file very carefully on the sides to allow them to move freely. Do not tighten the black plastic caps too hard or they will break, but they have to be snug. Be carefull.
Good luck. Neil.
