Converting Z To Use Std Digital Camera Battery, Using std Digital Camera Battery in the Options

[Marty]

I am seriously thinking of opening my SL5500 up to perform some surgery on it in order to take one of the stock digital camera batteries that I can get easily and cheaply. The benefits are that I can stick an Li Ion 1800 mah battery in the Z which I can buy for about £17 to £20.

My current sharp battery the EA-BL06 is not holding its charge and is difficult to get in the UK. (I have found one place charging 49 Euro )

I have the instructions on how to open the Z , and although I wont know until I look at the PCB in detail I am assuming I will just cut the tracks to the two outside terminal posts of the battery connector and wire them in reverse.
This may seem "excessive" but trust me the battery thing is wearing me out.

Almost all the digital camera battery have the opposite polarity from Z and you can get battery with the exact same footprint as the EA-BL06 if not slightly smaller so they will fit with a bit of plastic packing if need be.

Anyone think of any reason why I cant use a (good) digital camera in this way - I mean from the battery standpoint . The only thing I'am worried about is a muli layer track that I cant get access to. If I find that I may have to desolder the connector and isolate the two end pins completely.
Since Sharp pulled out their's not a lot left here in the uk for parts and support for the Z SL5500.

As far as li-ion charging is concerned, putting in a larger cell will just mean proportionately longer charging time. The charging circuit will only stop when the cell voltage reach around 4.1 or something.

You can think of it using buckets of water as an analogy. The voltage is the height of the buckets (batteries). The volume of the buckets is the capacity of the battery. So if the water (charging current) filling the buckets up is constant, it will just take longer to charge up.

Some older ni-cad chargers may use a timer, which is why they needed to discharge completely and then charge up. Otherwise, the water will overfill, ie the battery will explode.

Hope it makes sense.
