Hi,

Anyone know whether charging up my motorola phone with some AA batteries, a few voltage regulator diodes, a resistor and the connection from an old charger will have any long-term damage to my phone or not? I need an emergency portable battery charger that will charge up my phone without the mains from some alkaline batteries.

Because Lithium-Ion batteries need a special charger, is there any consequence of me charging it with alkalines? I'm really desperate for a portable charger eh...My Motorola e398 only lasts for 2 days tops, and when I use it a lot, it runs down even faster.

Hi Keith - is there any reason why a spare proper phone battery wont suffice? (try Phonestuff for non-original batteries)

You should have no problems, you can infact buy exactly what you are planning to make. Just ensure the voltage and current are the same.

A spare battery won't hold it's charge like an Alkaline does (I know, a bit silly because it takes a loooong time for it to lose its charge but still.....), and making your own alkaline to lithium ion charger would be infinitely cooler. University's just started so I'm only baking this idea in my mind at the moment and doing a bit of research. Would be damn useful though.


P.S, anyone seen that charger for the ipod made of AA batteries? It's a nifty idea. Cheers for the replies, any other comments would be good too.

Try this page here for a charger. It should give you a good idea of how to construct it and such like. I thought the USB plug was great as you can use a normal USB cable instead of having to chop up a cable to connect up to batteries.

Hey cheers,

My phone can't charge from a USB cable (Stupid designers) but thanks very much for the website, suddenly got an idea how to design myself. :) I've now seen about 6 different types of similar chargers and I think I can combine what I've learnt from each one to make my own. :)


Thanks guys,
Keith
