Battery problem (Giant Twist old model)

[Leonardo]

I've a problem with my battery (Giant Twist 2006). Leds are acting strangely. In past days sometimes it happened that they light up when I took the battery in my hands. Today they don't light when I press the check button nor when the battery it is connected to charger. Is it just a problem of the leds or is my battery cracking down?

No, the battery will be ok Leonardo. The LED meter circuit on this Panasonic battery is extremely sensitive and often gives trouble when a battery is recelled. In this case there's possibly a poor connection, but more likely a fault in the meter circuit itself. It's a tiny board combined with the LEDs and on the case wall, and the fact that finger pressure when picking it up has been changing the light status tends to indicate a problem on the board.

Charging time will be a rough indication of it charging ok, and as long as your charger stays reliable it shouldn't be too much of a problem. You or a suitable dealer could check the unlikely possibility that it's the wire connections at the board by opening the battery, but if soldering is needed it would be extremely fiddly.

You can see the back of the meter in this photo, it's the small green circuit board at the left with three wire connections, and there are nine case screws to undo to get the cover off:

Many thanks Flecc. I tried the bicycle this morninig and all the other things seem to go on working indeed. So I think I'll not touch anything at the moment.
