Stair lift
battery
Many stair lifts use battery
power.
Batteries are used in some
devices as a back-up power source when mains power shuts
off.
If there is a power cut that
shuts off mains electricity then the battery will help keep
the stair lift working.
And battery powered stair
lifts are claimed to offer a smooth ride quality.
Other stair lifts use
battery power as their single source of energy.
AC mains powered stair
lifts were once the dominant type of stair lift in the
market.
In recent years there has
been a switch to DC power.
A battery stair lift can
make more than 20 runs up and down stairs before it needs to
be recharged.
Some battery stair lifts
have a charger strip at the either end of the rail - so when
the stair lift reaches the end of the rail the battery will
be charged.
In the UK most stair
lift batteries are 12V 7ah rechargeable batteries with an
estimated life of two to three years.
Installation companies
recommend that batteries are only replaced by qualified
engineers - as carrying out the operation incorrectly can
affect the safety and running of the machine.
