[MDA III, XDA III, PDA2k, 9090 ROM Development] Mnemonique:
and yet here's another one by me on my ba.

(Part III of III)

Firstly, you need to prepare the materials :)

Unpacking the Batteries:

I did the BL-5C first, the paper casting it is like a sticker, you can either tear it all up, or you can carefully peel it off, either way it accomplished the general idea of unpacking it. :)

Unpacking BL-5C:

It's pretty straight-forward, since after you peel of the paper, you can see the silver colored naked battery with a black plastic outlining it. You can now push naked battery out starting at the bottom and just pull it off.

In picture (7) I have already pull off the battery against its black plastic outline, the black part that is still attached to BL-5C, I cut through the thin metallic part (all the way to the end) that is attached to the small circuit with diode/s on it, leaving me with a peeled battery, with a 3-4cm thin mettalic part that is soldered/attached at the side (NEGATIVE POLE), and a much longer one at the top of the battery (POSITIVE POLE).

Unpacking BA Bat:

This one is tricky and since I only have one battery to mess up, it's do or wait a week 'till your new battery arrives, the sticker can easily be peeled out but I didn't do mine entirely, I've just peeled of mine at the sides.

I firstly peel-off 3/4 of the sticker from the top, and used a ball-point pen to lever off the silver aluminum cover against the black plastic encasing the BA batt, after I did that, I then insert a butter knife, and lever it upwards, starting from the left side of the battery (facing the battery)

after you pulled out the aluminum cover, you can now see two batteries, placed together in one battery packed compartment.

Removing the battery from its compartment is easy, I suggest you remove the batteries one by one, to avoid shorting the battery circuit board with diodes and chips soldered to it :), be careful in cutting the thin metallic material connected from the battery to the one in the pic (labeled 03_unpack_battery13).

Side Notes:

You can temporarily placed a tape to cover the metallic conductor, so when you cut off the thin metallic material, you can avoid an accident by shorting the positive and the negative poles of the two batteries it would be helpful if the battery is empty, but the funny thing is just when do we allow our precious BA batt goes empty?

When I saw a short little spark or smell something burnt, I thought I've just damaged the original batt, and also thought this part (labeled 03_unpack_battery13.jpg) is the only thing that is damaged. I was wrong :(

What did I do with my 3-4 hours? burnt a plier, cursed myself, browsed online to look for a new battery, studied how to read an analog multi-meter (I only used one to for connectivity purposes):), I then found out that the batteries are okay, and decided to test for the last time before I announced my BA useless.

It just switch ON! lucky me.

to continue, 3-4 hours later I decided to continue my little adventure/misadventure.

In pic (05_re-pack01.jpg) I soldered back the wires I cut to test the battery with UTP wire and the BL-5C soldered to it the part (03_unpack_battery13) , (refer to pics 04_test01-04.jpg). I have difficulty in soldering, so I managed to place the BL-5C like we all do with rechargeable batteries (e.g. flaslight, digicam, etc.), yes, I didn't soldered the (2)BL-5C to the BA batt part (03_unpack_battery13.jpg). Why not? since the BL-5C magically fit at the BA battery compartment, not to mention the negative and positive poles of the n0kia batts, it's a coincidence that it fits right. :)

As you can see, BA is alive, it recharged and worked like a charm.

v2:

Later on, my BA just hangs, sometimes it restart itself, or worst just shut downs.

so I decided to removed this part (03_unpack_battery13.jpg), and the wires attached to the circuit board, since the original wires soldered to the circuit board is short, I've replaced them with green and orange colored UTP,

Original:

RED = Positive

BLACK = Negative

UTP Wire Mod:

Orange = Negative

Green = Positive

As you can see from the two pics, I have replaced the wires, soldred directly from the two utp wires, from the circuit board directly to the bl-5c.

Side Note:

To avoid batteries from moving, I've placed a very thin double adhesive tape at the back against the cover of the BA Battery.

I hope this helps.
