BATTERIES AND BATTERY CHARGING—FREQUENTLY ASKED QUESTIONS (FAQs)
How does the charger work?
When your Hurricane PMV’s battery voltage is low, the charger works extra and sends more electrical current to
the batteries to bring up their charge. As the voltage of the batteries approaches a full charge, the charger works
less to complete the charging cycle by sending less and less electrical current to the batteries. When the batteries
are fully charged, the current being sent to them from the charger is at nearly zero amperage. Therefore, when the
charger is plugged in, it maintains the charge on your Hurricane PMV’s batteries, but it does not overcharge them.
We do not recommend that you charge your Hurricane PMV’s batteries for more than 24 consecutive hours.
What does the LED on the charger indicate?
The green LED turns on after the batteries have been fully charged. In some instances, the green LED may stay on
after the charger has been unplugged from the wall outlet. Although users may perceive this as a charger malfunc-
tion, it is a normal condition. The green LED goes off when the batteries reach 26 VDC, which may take a few
minutes.
Can I use a different charger?
For the safest, most efficient, and balanced charging of your Hurricane PMV’s batteries, we prefer and highly
recommend the simultaneous charging of both batteries by use of the onboard battery charger.
How often must I charge the batteries?
Two major factors must be considered when deciding how often to charge your Hurricane PMV’s batteries.
! All day PMV use on a daily basis.
! Infrequent or sporadic PMV use.
With these considerations in mind, you can determine just how often and for how long you should charge your
Hurricane PMV’s batteries. We designed the onboard charger so that it does not overcharge your PMV’s batter-
ies (do not charge them for more than 24 consecutive hours). However, you may encounter some problems if you
do not charge your batteries often enough and if you do not charge them on a regular basis. Follow the five
guidelines below to provide safe and reliable battery operation and charging.
! If you use your Hurricane PMV daily, charge its batteries as soon as you finish using it for the day. Your
Hurricane PMV will be ready each morning to give you a “full day” of service. We recommend that you charge
your Hurricane PMV’s batteries for 8 to 14 hours after daily use.
! If you use your Hurricane PMV once a week or less, charge its batteries at least once a week for 12 to 14
hours at a time.
! Keep your Hurricane PMV’s batteries fully charged.
! Avoid deeply discharging your Hurricane PMV’s batteries.
! Do not charge your Hurricane PMV’s batteries for more than 24 consecutive hours.
