Iota Technical Paper - Charging Lead Acid Batteries for Long Life

Smart Owners Use Smart Chargers
Preventing sulfation and excessive gassing extends the lifetime and improves reli-
ability and safety of lead acid batteries. The IOTA IQ4 Smart Charging Technol-
ogy maintains proper battery charge to prevent the damaging effects caused by
the storage of batteries in an overcharged or undercharged state. When bat-
teries will not be used for long periods of time, storage in the proper full charge
state is crucial to reliable battery performance. IOTA IQ4 Smart Charging Tech-
nology delivers the necessary four-stage charging process for these ooded lead
acid battery applications, and brings battery users the condence of optimal life
and performance of their investment.
IOTA IQ4 Smart Charging Technol-
ogy is a four-phase charge controller
for IOTA DLS Series Battery Chargers
to automate multi-stage charging of
12V-48V ooded lead acid batteries.
The IQ4 uses the four phases – bulk,
absorption, oat and equalization
– to maintain a proper full charge to
extend battery life.
IQ4 Smart Charge Technology is
available as an integrated option in
IOTA DLS Series Battery Chargers or
as a separate module that connects to
the DLS charger.

What about using Smart
Charge Technology with
other battery types?
?
Different battery types (sealed lead
acid, AGM, etc.) often require unique
charging stages to properly maintain
the battery. The charging parameters
discussed here are applicable to ood-
ed lead acid batteries. Be aware that
some available smart chargers may
not be suitable for other applications.
