DCPower Batteries DC120833 Operating Instructions Manual

602 Tremaine Avenue

Palmerston North

06 3590834

CAUTION

1.

Please read any battery cautions prior to charging!

2.

When charging, batteries can emit explosive gases therefore it is essential
to prevent flames and sparks. The charger is designed for charging sealed
lead-acid batteries from 2 to 60 Ah - to an end voltage of 14.4V / 14.7V.

3.

Always provide good ventilation when charging.

4.

To reduce risk of damage to electric plug and cord, pull by the plug rather
than by the cord when disconnecting charger.

5.

An extension cord should not be used unless absolutely necessary. Use of
an improper extension cord could result in a risk of fire and electric shock.

6.

Do not operate charger with a damaged cord or plug. Return the charger to
the place where purchased for repairs.

7.

Never operate the charger if it has received a sharp blow, been dropped or
otherwise damaged in any way. Take it to a qualified serviceman for testing.

8.

Do not disassemble the charger; take it to a qualified serviceman when
service or repair is required. Incorrect reassembly may result in a risk of
electrical shock or fire.

9.

To reduce risk of electric shock, unplug charger from AC outlet before
attempting any maintenance or cleaning. Turning off controls will not reduce
the risk.

12V Sealed Lead-Acid Battery Charger

Operating

Instructions

Introduction

The DC120833 is programmed for an automatic four stage (Ud-I-Uo-Up) charging

process. It is designed for 12V, 2 to 60Ah sealed lead-acid batteries. It is also ideal for

keeping all other lead acid battery types “topped up” and maintained. Stage “Ud” is for

assisting with de-sulfating the battery through a pulse charge process. When battery is

sufficiently recovered, stage “I” will give bulk current charging (0.8A or 3.3A, defined by

user). Then, “Uo” stage follows where the current is reduced and the output voltage is

regulated to 14.4V (14.7V is for low temperature selection (Snow symbol)). When the

current is [automatically] reduced to 0.4A, stage ”Up” begins. At the completion of this

stage, the battery is charged completely and the charge cycle is finished. The charger

will enter pulse charge mode again when the battery voltage drops below 12.90V, thus

maintaining the battery as fully charged.

For 2 to 12Ah battery, select 0.8A (Motorcycle symbol) and for 12 to 60Ah battery, select

3.3A (Car symbol).The (Snow symbol) mode is also suitable for batteries requiring 14.7V

Charger will not overcharge “sealed” lead acid batteries. Although this charger can be used on “wet”

batteries and is in fact ideal for maintaining them, it is not suitable for Calcium types when discharged.

How to use:

1.

Connect positive clip (red) to positive battery terminal, the black clip to negative.

2.

Connect the AC cord to the power outlet. The red alarm indication light will

indicate a battery which is connected in reverse polarity.

3.

Pressing the “MODE” (MD) button and stepping forward one press at a time until

the required mode is reached.

4.

When the “charging finished” led lights up, the battery is fully charged. Leave the

battery connected for maintenance charging.

5.

When disconnecting charger, disconnect in reverse sequence from connecting.

The table shows the duration of Bulk step-up to about 80% state of charge.
