WHAT CONSUMERS NEED TO KNOW ABOUT
POWER MOBILITY PRODUCTS
(Recommendations courtesy of Invacare & MK Battery)
Batteries:
* ALWAYS follow the manufacturers recommendations for battery type and
size.
* ALWAYS use Deep Cycle batteries, due to the fact that they are designed
to be discharged and recharged on a regular basis.
* Cold Cranking Amp or Marine type batteries are for starting purposes
only, and are not intended for power mobility products.
* Deep Cycle batteries are FAA and DOT approved and are the safest for
transport both private and public.
* Deep Cycle batteries are Maintenance Free batteries, NEVER open or modify.
* Deep Cycle batteries DO NOT have a memory.
* NEVER allow Deep cycle batteries to completely discharge.
* The depth of discharge does effect the life of Deep Cycles batteries, the
greater the discharge the sooner they will need replaced.
Charging Systems:
* Use only manufacturers charger on all models, and no more than 8
amps MAX.
* Charge Deep Cycle batteries frequently to maintain a high level of
charge.
* Charge mobilty products with the power “ON” to reduce current rollback.
* All Deep Cycle batteries have a Break In Period of 20 days. Charge
power mobility products everyday for the first 20 days reguardless of use.
* Charging of power mobility products may take 8 hours under normal use
and up to 16 hours with severely discharged products.
* NEVER top off power mobility products with short charges, once recharging
begins it must be allowed to finish. This could take +10 hours.
* NEVER leave charger connected for times exceeding 36 hours.
* NEVER charge power mobility products with both an ON-BOARD & OFFBOARD chargers at same time.
* DO NOT use an extension cord to charge power mobility products.
* DO NOT charge power mobility products outside.
* Chargers may get warm, if excessive heat is detected, discontinue and call
dealer.
Storing Batteries:
All batteries should be fully charged before putting the unit away for storage (regardless
of storage lengthof time). It is also recommended that you disconnect the main power
source, to avoid the possibility of discharging the batteries (which could cause permanent damage).
