I am attempting to create another tiny amp... but I am in need of tiny rechargeable batteries. I have been looking for hours... but haven't had much luck. So, I thought maybe you all could help... The maximum size of these little suckers would be 15mm W x 20mm L x 25mm H. I also need AT LEAST 150mAH.... but would prefer much > 200mAH, if possible. 1.5V is possible... if the case size is small enough so i can series some of them... but I would prefer 3V and above.
I would like lithium... they would defintely have the current... but those cost a fortune and are not rechargeable. So... any suggestions? Or can lithium be recharged safely?
Can alkaline, manganese dioxide, silver oxide, zinc air, or carbon zinc be recharged with much success?
