Could someone advise me what would happen if I .....
well I have a step watch which uses a 3.7V 90 mAH 302020 battery... which for some reason doesn't hold its charge no more ....
what would happen if I got two new batteries and wired those to the unit . Would it (I know not much with electronics) be two powerful to run the unit and if this is ok would I be able to charge them together or would that not work ?
