Hi,
Firstly, erm, I've kinda been asking alot of questions recently...I'm sorry if you're getting fed up! Please say if you are! It's just I'm a bit of an enthusiastic newbie...
Anyway, I was wondering if anyone can help me with something. I was trying to figure out with some school friends how to determine when a battery is going to run low in x amount of time or less. For example, you may find this feature on, I dunno, perhaps medical equipment or a smoke alarm or something. I was thinking that perhaps you could have a seperate battery that kicks in once the normal one dies to light an LED or sound a buzzer or somthing...but then what if that battery ran out...
Thanx in advance for any ideas on this,
Jon
