Does anyone have battery replacement procedure?? Can I replace this NiCad with a 3V Lithium? I have heard yes but also need to remove a diod so that the Lithium does not try and take a charge. I just picked up a SX 240 and it is perfect even the NiCad loooks ok but I do not want to leave it in there. The DX7 has some nice step by step pics for Battery replacement, I was hoping there was one for the SX240? Thanks! Jason

In fact you need to add a diode to prevent current from going in the lithium battery. (It's easy to place in series with the battery resistor) -- Antoine Deschênes 2009/5/11 waketek <djwaketek@...>:

Is there a place on the board to add the diode or do I just need to go R,D,Batt. I am just trying to clarify as I have been told several different things which are different, one person told me to remove a diode, another told me to remove a resister, now you are saying keep the Resister then add a diode between the Resister and the Battery? Correct? I appreciate the response! Jason --- In kawai-teisco@yahoogroups.com, Antoine Deschênes <antdes45@...> wrote:

You can put the diode before or after the resistor, it doesn't matter, but check the diode orientation. What you can do is to mount the resistor and diode vertically by unsoldering one pin of the resistor, putting one of the diode's pins in it's place, and twist both remaining pins together. I think it's better to keep the resistor soldered as it prevents the battery from being shorted, it will probably reduce the circuit's consumption a little bit, and protect the battery if the diode ever shorts for a reason or another. I'll try to take a picture of what I've done in my SX240 this week. -- Antoine Deschênes 2009/5/11 waketek <djwaketek@...>:

This is what was done to mine before I bought it from the member here. boardjunkie my 240 I used a "AA" size battery holder and found a 3.6v lithium battery in the AA size. Used silicone glue to secure the batt holder to the pcb and ran the leads (with a diode in series, 1N400x will do) back to where the original battery tabs soldered down. I'm sure there's a fancier way to do it, but it works just fine. The series diode keeps the charging circuit from attempting to charge the lithium battery. I opened my sx240 up a few times in the time I owned it for a tech to trying to track a minor issue.He was unable to find the issue but it was going strong at about 98% .Then one day my sx then decided to fix it self as crazy as thats sounds it did I was like wtf .My sx240 has done me well and just in case I decided to get some spare chips if that issue ever comes Im coverd. --- In kawai-teisco@yahoogroups.com, "waketek" <djwaketek@...> wrote:
