Battery

abuse

or

mishandling

can

cause

the

battery

to

overheat,

which

can

cause

gasses

or

flame

to

“vent”

from

the

battery

pack

or

coin

cell.

If

your

battery

is

damaged,

or

if

you

notice

any

discharge

from

your

battery

or

the

buildup

of

foreign

materials

on

the

battery

leads,

stop

using

the

battery

and

obtain

a

replacement

from

the

battery

manufacturer.

Batteries

can

degrade

when

they

are

left

unused

for

long

periods

of

time.

For

some

rechargeable

batteries

(particularly

Lithium

Ion

batteries),

leaving

a

battery

unused

in

a

discharged

state

could

increase

the

risk

of

a

battery

short

circuit,

which

could

shorten

the

life

of

the

battery

and

can

also

pose

a

safety

hazard.

Do

not

let

rechargeable

Lithium-Ion

batteries

completely

discharge

or

store

these

batteries

in

a

discharged

state.

Heat

and

product

ventilation

Computers

generate

heat

when

turned

on

and

when

batteries

are

charging.

Notebook

PCs

can

generate

a

significant

amount

of

heat

due

to

their

compact

size.

Always

follow

these

basic

precautions:

v

Do

not

leave

the

base

of

your

computer

in

contact

with

your

lap

or

any

part

of

your

body

for

an

extended

period

when

the

computer

is

functioning

or

when

the

battery

is

charging.

Your

computer

produces

some

heat

during

normal

operation.

Extended

contact

with

the

body

could

cause

discomfort

or,

potentially,

a

skin

burn.

v

Do

not

operate

your

computer

or

charge

the

battery

near

flammable

materials

or

in

explosive

environments.
