Hi

I have just bought a metal detector which has a rechargeable 12 volt 1600 mAh NiMH battery. As I bought it in the States the battery charger is rated at 110 V AC 60 Hz - 15 V DC 100 mA.
I am having difficulty in sourcing a charger with the same output with 240 V AC 50 Hz input, can anyone point me in the correct direction please? Tried Farnells, Maplins etc.
I have a charger with an output of 15 V DC 1.5 A will using this risk damaging the battery pack?

Regards Mick

No it wont harm the battery. current is pulled by the battery being charged, and not pushed by the charging transformer, so it shouldnt make any difference. if the battery tries to pull a little bit more with this new charger id have though it would justcharge a bit quicker

e-bay perhaps?

"NEW 15V 100mA 0.1A AC/DC Power ac adapter Power Supply"

No idea about whether 1.5A is too much, I know these new types of battery have low internal resistance though.

try this us-uk ac convertor. ATB Martin

Agree - best to sort out the input voltage, then you know the output is correct for your device.

Go to a model shop and buy a smart charger. There are lots to choose from and the shop staff should be able to advise on the best one. Do am internet search for BRC they do mainly electric RC stuff and have loads on their site.

As long as the output voltage is the same then the battery will draw what it needs. If you are worried, put an inline slow blow fuse at about 200mA in one of the battery leads.

Hi

Thanks for the advice - plenty of food for thought / options there.
