WARNING There is a danger of explosion if the battery is incorrectly
installed. For your safety, never attempt to recharge,
disassemble, or burn the old battery. Replace the battery only
with the same or equivalent type recommended by the
manufacturer. The battery is a lithium battery which does not
contain heavy metals. Nevertheless, in order to protect the
environment, do not dispose of batteries in household waste.
Please return used batteries to the shop from which you bought
them, or to the dealer from whom you purchased your
Workstation, or to HP, so that they can be either recycled or
disposed of in an environmentally sound way. Returned
batteries will be accepted free of charge.
