Trickle Charger BD-10

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 battery.

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.
