 07 Jul 2008 11:24 Help! Newbie with question on battery charging |
|
|

Hi folks,
I must confess I know little or nothing about electronics, but I am hoping someone here might be able to help me with a specific question.
I have an obscure electronic gadget powered by a rechargable battery but no charger for it. The item itself has a fairly standard charger connection, but I am not sure if I can use a generic charger or whether this will fry the device or battery.
The battery itself is rated as follows: 3,6v lithium ion 3400 mAh
I have a charging adapter with various connections, switchable polarity, and voltages of 1.5v, 3v, 4.5v 6v, etc but I am not sure whether it is possible or dangerous to use this.
I'd be really grateful if someone with a better understanding of all this could advise me whether I can use this and if so what setting, or if not whether there is anything from Maplins etc that would work?
Thanks in anticipation!
Ali

you have charging adapter , that is supply with your battery then you can use it with 4.5 volt .
you havn't write here what is current capacity of your adapter ? and it is SMPS or or simple stepdown transformer adeptor?
you have battery capacity is 3800 MA. so i think you need hagher current rating adapter.
how much contect at battery ? -Ve and +ve only or more like cell phone battery?
same for adapter there is any socket for battery connect oor not? how much contect for connect battery?

| pls use in 4.5v mode with proper polarity. otherwise it may be damaged. At first connect charger 5 to 10 mins & check any abnormalities like... heat,etc..if not try it..

If it is SMPS then use 4.5V but if it is a simple linear adapter then first check the voltage at 4.5V, I guess it will be more than the expected.
