i have a rechargable 9v battery (9V 175mAh) and i wanna charge it but i dont have a charger. its chemistry is NIMH. so is it possible to charge it with any other batteries? i have some wire, and battery holders for 2x AA and 9V. im asking because i dont want to die in a battery explosion. I have lots of battery holders but 2x AA and 9V are the only kinds. i have 1.5V (AA, AAA, C, D) batteries, a 12V sealed lead acid battery, and 2 coppertop duracell batteries. can i charge my 9v using other batteries? and if i can, how?
