Application
- When batteries age and/or spend too much time in a
discharged or abused state, sulphite crystals can form on the battery
plates which inpede the flow of electricity
and is the main cause of poor battery performance. This unit is a basic
battery desulphator
with advanced control techiques married with a 3 amp MPPT charge
controller. Its primary function is to be used as a trickle
charger/desulphator to keep a battery that is in storage, say an RV
battery over the winter, in fully charged state and ready to go, or to
recover badly sulphated battery to near new condition. This unit
emphasizes extremely low cost and premium performance.
Basic Operation
This unit is a 3 amp charge controller married with a battery
desulphator. It is used to recover a a badly sulphated battery or to
maintain a battery in storage for a significant time.
Charge Controller Section:
The charge Controller is a 12 V @3 amp nominal MPPT that can
take as an input a 30 W solar panel or a 20 - 40 VA 16 V Class 2
transfomer (Doorbell transformer) and charge control a 12 V nominal
Lead acid Battery. It includes battery fusing. Its output is pure DC
and it will maintain a charge on the batery.
Desulphator section:
Sulphite crystals form when the battery charge is reduced and/or the
discharge/
discharge cycles are not well suited for the battery. These sulphite
crystals
act as insulators to the flow of electricity in the battery, seriously
degrading the
capability of the battery to have electricity flow in it, reducing its
charging and
discharge capability.
Like most battery desulphators, this unit uses a sharp pulse of
current
forced into the battery suddenly to "jar" the sulphite crystals and
cause
internal resonances, both mechanical and electrical, to grind down the
sulphite crystals that form so they can be re-combined into the battery
acid.
With the high quality charge controller, this unit can desulphate
and recover a very dead battery. In our testing it has recovered a
number of car type batteries left in landfill for over 3 years.
Note: It will not recover batteries that have other ailments to then,
ex shorted cells, lack of acid etc.
