Battery will not charge

a good routine is to purchase a battery tester. hold the tester on and see if the output drops after a period of time.
Usually Batteries (when used) only uses a certain amount before they are charged..
When this happens The battery is only using the same cells within the battery & NOT using the full battery potential.
When this happens The battery life shortens & When charged The battery Will Indicate Fully charged But The Battery Life Is Reduced Because they Way it has been used & Charged. Always Use a Battery From fully Charged to Almost Flat Before Fully charging your battery. Also Don't be afraid of Over Charging your battery when it indicates Full. But not Too Much... Maybe an extra Hour or 2 tops.

Once the green light goes off, it's done charging. Since it was first charge I know they say to charge it 8? hours (or 4? don't recall right offhand) but it does come charged (that's part of how they make the batteries). What you do want to do is remember not to always recharge it when your done using it. Use it till the battery goes flat, then recharge it; it will give you a longer battery life that way.

no start using it , but keep charging it when not in use

Hi,

If your battery is flat or close to, then a complete charge is ussually 23 hours. or thereabout, so this is why the light on your charger is still on. The light for a flat battery is red and when the battery is fuuly charges light is green.

8 hours of charging a flat battery, isn't enough, hence the light staying on RED, if I'm not wrong and I doubt that I am.

I hope this has answered your query.

Best regards,
Peter

Wait for the 6 hours that they ask you to, as that will be when the battery is fully charged and is at peak performance.

The manual says that a red light is a charging error. Green means it is charging and the light goes out when charging is complete.

The camera must be turned off when charging the battery. They recommend a full 8 hour charge for a new battery, then allow it to discharge completely (leave the camera on I guess) and charge it again "before use".

You can download the manual from this page. Select the "Resources" tab.

When you connect the charger, if the light goes to red to green within a few minutes and the battery power does not last more than 1-2 hours or less, it may indicate that that the batteries will not take a charge anymore and need to be replaced. This can happen if the power chair has not been charged in a while or has been stored. Having the chair on or off while charging will not affect the charging process, but you ususally want it to be OFF.
Good luck!

Here is the manual:

Red = quick charge
yellow = evaluating
green = charged

CHARGING A COOL BATTERY PACK
If battery pack is within normal temperature range, the red LED on charger will come on.

Red LED should remain on for approximately 1 hour then the green LED will come on. Green LED on indicates battery pack is fully charged and charger is in maintenance charge mode.

The green light on the charger usually indicates that the batteries are fully charged and you are ready to go. Does the controller show the batteries are fully charged? Can you operate the power wheel chair for several hours? If so, you are good to go.
When you connect the charger, if the light goes to red to green within a few minutes and the battery power does not last more than 1-2 hours or less, it may indicate that that the batteries will not take a charge anymore and need to be replaced.

you should charge it with the laptop off for at least 24 hours this shoud fix that new batteries need a 24 hour charge
