yup it's too dangerous. Think about it...batteries do explode if this is soldered wrong. Remember the Dell/Sony battery recall? I would rather pay extra for the sense of security then be frugal and have to constantly check up on the hacked battery just to make sure it doesn't catch on fire.
the soldering process looks very dangerous, well if you want to risk loosing a limb to save $70, go for it lols.
i think the problem with the "exploding" laptop batteries wasn't the power container themselves, it was some controller for it. So as long as the battery was working fine before and you don't solder something that doens't belong, you shouldn't have any problems with this hack. And the batteries themselves exploding, despite his warning about the lithon batteries, you'd have to be working with the intent of burning a hole through the battery to get it to explode. Worthwhile hack, it has a secondary comp for him.... plus he got better battery replacements compared to his old ones
i say just keep the mains plugged in, even with new batteries, laptop aint gonna last long on battery
^lol its not that hard considering it isnt soldering small intricate components... its just soldering wires to large strips of metal
I think my laptop (Dell Inspirion 6000) battery are those same sized batteries...but doesnt matter, as long as output is the same u can have what ever size capacity.
