How can I open my Bosch 18V 2.6Ah Ni-MH Battery? ?

If the batteries have been left totaly drained for to long, they are dead. To long is anything longer a day.
This hold for ALL Li-ion or Li-MH batteries.

If left unused for several months, they will slowly loose their charge. After about 6 months, the remaining charge become criticaly low. You must put them back in the charger.

If it's a Ni-Cd battery, it needs to be totaly discharged before you recharge because of it's memory. Those can be left drained.
