Battery Problems?

[AmirasDaddy]

The problem is the battery drains not quickly I might add after a week or so of usage the battery is so low a voltage it wont let the starter motor kick in however this is not the problem when fully charged, I got the battery from the same place as my dad and his turned out to be a dud according to his mechanic, so I had it on charge for a few hours and after I had taken it off charge the battery was emitting a strange noise, sort of high pitched if you know what I mean, put it back in the bike and it started right away.

Bike is 2002 Peugeot Vivacity 100cc

Any help is greatly appreciated.

Duff battery by the sound of it, if its new take it back and buy a good quality one.

A battery making a high pitched noise is never a good sign. With a lead acid (semi transparent casing) battery it could be a sign of a partially blocked breather. These batteries emit hydrogen gas when working or charging, and have a breather hole to let the gas out. Sometimes they'll hiss a little when charging hard, and bubble if you tip them back and forth. If the breather is blocked then the gas is pressurising inside, which is a bad thing.

If a maintenance free battery is whining then I would expect an internal fault, either caused by charging it too hard or by dropping it.

Either way I would say the battery is goosed. Get a new one and see if the problem persists, if it does then you're looking at a fault in the charging system or the reg/rec, both of which are more expensive or time consuming to fix than a battery.

Be sure to charge the new battery for several hours using a bike charger, or a car charger with a bike setting. A car charger will put out too much current to safely charge a new scooter battery.
