Just whipped up a charging circuit, but I still can't find an applicable battery.

I can't find a 2.5v

The battery shown is not 2.5v. Its 2.4v. You can buy them at CPC CHS etc in the UK. Its the back up battery used in a Ferguson FV55 VCR
adding aresistor in series and a Zener is not a charging circuit either. All you are doing is reducing the charging current. If the zener is added as reference diode and the charging voltage exceeds the threshold voltage for the zener the zener will go short circuit.
To work correctly you need more than to limit current to the battery. you need a way of monitoring the charged state of the battery and cutting off the charge current when the battery is at capacity.

AS soon as I work out the bugs, I'll post a scematic, and no, the circuit is not just a Zener diode and a resistor, however in some XBoxes that are on for exfended periods of time, a resistor would be nice.

Good man. It sounded like that was going to be it but obviously you are doing it the correct way. Stick the pics up whenever and if you want the mod hosting i will stick it on my site for you if you want to do a little how to. Your name will be credited to the work

TKramka · « **Reply #22 on:** April 22, 2005, 06:09:00 PM »

And the correct battery voltage and where it came from. I'll post some pics as I work on this.

didnt u read his post that he said he got a charging circuit working or nearly working?

And that has what to do with the actual design of it or me hosting the pics and stuff.
keep quiet

know it all asshole

where is your constructive help (criticism or other) other than saying "that would be a good idea" or commenting on if I read his reply when i clearly did. all you have is waffle.

), plus there are things that could be done better, my experience in the past tells me that if I made it in 3 days, there is something that could be improved. Plus I'd like to wait until my laptop comes back from Compaq (right now I'm using a PII, ugh!), it has Photoshop on it, and I could draw a better blueprint / take pictures. But don't worry, as soon as it get back, I'll draw a rough blueprint for people to tweak or whatever. Today I'm consulting with my friend who is an electrician, it's kind of a joint effort between us.

Hmm, anyone think I should make it variable voltage? Its do-able with a switch and some more parts, but harder to make. Ex, 2.4v or 3.0v for those who use 2 AAA batts in series and those who use the VCR battery, why anyone would put a battery in a VCR boggles my mind (RTC?).
