DX7 charging

[Smoothy]

Hi

Silly question but!
I have a DX7 with std battery pack, can anyone tell me how long it takes to charge with a 150mA charger.

150 mah X 10hrs = 1500 mah.

Have you charged it before? Are you new to DX7? only asking because pos/neg are the reverse on spektrum. Some people don't realise and use a normal charger and wonder why it won't charge up.

Thanks

Got the polarity sorted thanks.
