NiCad / NiMH Battery Repacking
Wondering if anyone knows a good place to get this done in Melbourne?
(No, it is not for a drill etc, so buying a new one as a cheap alternative is not an option!)"Clear, Ease Springs"

I know... here we go again!!
Surely it can't be impossible to buy the batteries and solder them together?
Just where do they come from though?
P:confused:

Thanks Chris - Yellow pages failed me
It wasn't for me, otherwise I would have already done the soldering iron thing! Just knew someone on the board would know someone!

General note:
Before you pick up an iron be sure to educate yourself on the dangers of these batteries.

I have just had a laptop battery repacked by Battery World. A franchise in NSW, don't know if they are in Vic.
A new one would have cost me $280.00 and the repacked one has cost me $199.00. and the they have informed me that the repacked one has a higher Amp Hour rating and will hold a charge longer.
I pick it up on Friday will report on it when I have used it for a while.

I believe the terminals are welded onto the batteries due to soldering causing heat soak in the battery and affecting the internals. I cannot vouch for this it is something I read recently in one of the RC forums IIRC. As said earlier do it at your own risk. LiPos should be avoided at all costs, these things are bombs waiting to go off.

Have some nice pics of a burnt out 4wd that was charging cells via the cig lighter on the way to the flying field. Some now only charge in a fire proof charging area. ie bricks with a plastic bag of sand over the top. Cell explodes, plastic burns, sand smothers the flames etc.

LITHIUM BATTERY SAFETY SHEET
Please be sure to read and follow these instructions carefully.
Safety in using Polymer cells or assemblies is your first priority.
If you cannot comply with the safe handling of Polymer cells or assemblies then do not use them.
If you do not understand the characteristics of Polymer cells or assemblies then do not use them.
Safe Charging
Lithium Polymer cells have very strict charging requirements.
Always charge Lithium Polymer cells or packs with recommended charger or great damage may occur.
Always use chargers specifically approved for Lithium Polymer cells or packs.
Always test your charger to assure it is functioning properly.
Always charge your Lithium Polymer cells or packs outdoors and in a fire proof container.
Always store Lithium Polymer cells or packs in a fire proof container.
Always have sand or dry fire extinguisher handy in the event of fire.
Always keep any battery out of the reach of children.
Always handle Lithium Polymer cells and packs with great care.
Always purchase a factory authorized built pack instead of building your own.
Always observe the correct polarity when connecting cells or packs to charger or application.
Always seek medical attention if electrolyte gets in your eyes (flush with cold water immediately).
Always scrub with soap and water if electrolyte comes in contact with your skin.
Never charge Lithium Polymer cells or packs unattended.
Never charge Lithium Polymer beyond factory specifications and is strictly prohibited.
Never charge Lithium Polymer in your car, home or garage or where other physical damage can occur.
Never charge Lithium Polymer while in the application as the hot pack may ignite certain materials.
Never charge Lithium Polymer on flammable materials such as wood, foam or plastic.
Never extinguish a Lithium Polymer fire with water.
Never disassemble a Lithium Polymer cell or pack
Never short circuit Lithium Polymer cells or packs.
Never use a Lithium Polymer cell or pack that has been damaged
Never put loose cells with uncovered terminals in your pocket, purse, bag, desk drawer, etc.
Never keep cells or packs in temperatures that exceed 60C/140F.
Never exceed the factories maximum allowed discharge rates.
Never combine different cell sizes or capacities together in the same pack
Damaged cells or packs
In the event your cells or packs were involved in a crash.....
Totally inspect the cells, wire leads and connections for possible short circuit.
If there is any doubt completely cut all wires from the cells and pack.
If any cells are dented or deformed do not use the pack again ever.
Follow disposal notes below.
Disposal of cells or packs
Discharge all cells individually to recommended cut-off voltage of 3.0 volts per cell.
Caution!! Cells may be warm or hot as usual during this discharge process.
After cooling, puncture small hole in cells and immerse in salt water for several hours.
Apply tape over one terminal and dispose of in trash.
Follow all safety directions to prevent accidents or damage to persons or property.
