Just be careful with that - some time ago, I was using external charger extensively, and fixing those pins a lot. After some time, one of them fall apart... I ended up replacing whole PCB - when I did dual-scud 3000 mAh battery, I got one spare pcb with pins, so I repaired my original Nokia battery with it.
- bend these 3 battery contacts too, (mines were to loose for using a universal charger)
