 NOTICE/AVIS

MTI recommends the following procedure be followed in order to 
ensure that the battery is always ready for use and maintains a 
higher life expectancy.
MTI recommande de suivre la procédure suivante afin de s’assurer 
que la batterie est toujours prête à être utilisée et conserve une 
durée de vie plus longue.

MTI provides (2) batteries for each stretcher bed purchased. Best 
practices are as follows:

1. 

At the end of the day remove the battery from the stretcher 

bed and charge it.

2. 

Before the next surgery, insert a fully charged battery into 

the stretcher bed.

3. 

Alternate batteries every day.

 NOTICE/AVIS

Leaving the battery on the charger, even when fully charged, will not 
damage the battery or the charger.
Le fait de laisser la batterie sur le chargeur, même lorsqu’il est 
complètement chargé, n’endommagera pas la batterie ou le 
chargeur.

Charge time for a fully depleted battery should typically be less 
than 2 hours, at which time the green LED on the charger should 
be solid and the fuel gauge on the end of the battery should 
show five bars.

Discharging

with a battery inserted into the stretcher bed battery holster. 
If AC power is removed or unplugged, the stretcher bed will 
automatically switch to battery power.
