Woods Battery Chargers

The WOODS DIALOcharge is a sophisticated electronic, manually operated charger suitable for most types of batteries.

We have been using these for over 20 years.  They are robust, reliable and protect the batteries.

The Woods DIALOcharge is a sophisticated electronic manually operated charger for most types of batteries. It employs a primary phase-shift controlled triac to precisely supply charging voltages and currents during the recharge cycle. The DIALOcharge successfully recovers deeply discharged batteries. The DIALOcharge covers a variable range of battery voltages which provides charging flexibility in the workshop arena (eg: a 24V DIALOcharge will charge batteries of any voltage from single 2V cells to 24V systems). Due to the precise power control provided by the DIALOcharge, it may be used for fast recharging of operational batteries or for overnight trickle charge situations.

  Current is displayed by operator using dial on front of charger.
  This unit is not automatic and charging needs to be terminated by operator.
  Heavy duty components.
  Dualmeter reads amps and volts.
  Input switch breaker and output fuse provide total electrical protection.
  Compact and portable


240 volt ac mains or generator supply - While the mains input is predetermined for Australian conditions with a mild variance in the supply volts & hertz, remote use is available via generated power with an acceptable level THD% tolerance. Also available in 110Vac by order.

Available in 12, 24, 30, 36 and 48 volt - A vast range of battery terminal voltages are available 12Vdc to beyond 48Vdc up to 144Vdc.

Available in 15A, 30A, 60A and 120Amp - The larger your battery system and loadings, the larger your charger should be to quickly bring depleted batteries back into service.


Circuit breakers on input and output - Over current protection on both the mains input and the battery output is offered for immediate protection. The manual resettable switch circuit type breakers are of industrial grade.

Temperature controlled fan cooling - The rectifier assembly is protected by an automatic thermoswitch. If the temperature rises above its preset level the fan will be enabled until it has cooled the system to below its lower setting. This extends the fan's operating life.

Rectifier over-temperature shutdown - The second temperature protection device is also on the rectifier assembly. If, due to severe loading or other fault, the temperature exceeds its level, it will shut the battery charger down until the cooling fan brings the temperature back within safe operating levels.

Transformer over-temperature shutdown - The third temperature protection device is deep within core of the power transformer. Activation of this device indicates serious overheating and will shutdown operation of the battery charger until the cooling fan brings the temperature back within safe operating levels.


Manual phase-shifted control - The primary control circuitry is manually controlled by the user.

Employing heavy-duty passive components provides seamless and precise power control from zero to maximum output.

Voltage Regulation and Current Limiting - Combined with the power control, the DIALOcharge incorporates electronic voltage regulation and current limiting for complete charging protection.


Wide range - due to the flexibility of the controls, nearly all large batteries can be recharged with DIALOcharge.

eg: Wet Lead-Acid, Deep Cycle Lead Acid, Lead-calcium, Wet Ni-Cad, Genesis®/Optima®, etc.


Metering - An accurate electronically driven analog moving-coil meter is fitted as standard.

The Dual Meter displays the charging current, but the battery volts may be displayed at the press of a button.

They are large and easy-to-read with wide angle visibility.


Strong, durable, attractive - Powder-coated zinc-annealed steel cabinets.

DIALOcharge may be mounted either on a bench or shelf by the base, or on a wall by the back of the cabinet.

Portability - Due to compactness, DIALOcharge units are portable if needed.


Safety Standards - IEC33-2-29 (AS3350.2.29), IEC61558-1:1997 (AS/NZS61558.1:2000)
EMC Standads - EN55014 (CISPR14, AS1044), EN55022 (CISPR22, AS3548), EN50082-1
IP Rating - IP21
