b) Never place charger directly above battery being charged; gases from battery will
corrode and damage charger.
c) Never allow battery acid to drip on charger when reading electrolyte specific gravity
or filling battery.
d) Do not operate charger in a closed-in area or restrict ventilation in any way.
e) Do not set a battery on top of charger.
14) DC CONNECTION PRECAUTIONS
a) Connect and disconnect dc output clips only after setting any charger switches to
offposition and removing ac cord from electric outlet. Never allow clips to touch
each other.
b) Attach clips to battery and chassis as indicated in 15(e), 15(f), and 16(b) through
16(d).
15) FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN VEHICLE. A SPARK
NEAR BATTERY MAY CAUSE BATTERY EXPLOSION. TO REDUCE RISK OF A
SPARK NEAR BATTERY:
a) Position ac and dc cords to reduce risk of damage by hood, door, or moving engine
part.
b) Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to
persons.
c) Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has
larger diameter than NEGATIVE (NEG, N,–) post.
d) Determine which post of battery is grounded (connected) to the chassis. If negative
post is grounded to chassis (as in most vehicles), see (e). If positive post is
grounded to the chassis, see (f).
e) For negative-grounded vehicle, connect POSITIVE (RED) clip from battery charger
to POSITIVE (POS, P, +) ungrounded post of battery. Connect NEGATIVE (BLACK)
clip to vehicle chassis or engine block away from battery. Do not connect clip to
carburetor, fuel lines, or sheet-metal body parts. Connect to a heavy gage metal
part of the frame or engine block.

Overview

1. Function Description
2. Usage Features
3. Maintenance Features

The Deltran Battery Tender® Plus is a battery charger designed for six-cell lead-acid batteries, offering automatic charging and battery status monitoring. It is engineered to provide a spark-free connection and maintain batteries at full charge for extended periods.

Function Description:

The primary function of the Battery Tender® Plus is to charge and maintain six-cell lead-acid batteries. It operates automatically, adjusting its output power, voltage, and current based on the battery's condition. The charger features a microprocessor that ensures proper functioning and initiates charging only when it senses at least 3 volts from the battery, preventing it from attempting to charge deeply discharged or defective batteries below this threshold. This safety mechanism also means that the output clips or ring terminals will not spark when touched together, as the charger will not produce an output voltage until correctly connected to a battery with the proper polarity.

The charging process involves three primary modes:

1. Bulk Mode: In this initial stage, the battery is between 0% and 85% charged. The charger delivers a constant current to rapidly bring the battery's charge level up.
2. Absorption Mode: Once the battery reaches 85% to 100% charge, the charger switches to a high constant voltage mode, ensuring a complete charge without overcharging.
3. Storage/Float Maintenance Mode: After the battery is fully charged (100% to 103%), the charger enters a low constant voltage mode. In this mode, it continuously monitors and maintains the battery at full charge, preventing self-discharge and extending battery life. This feature allows the charger to be left connected to the battery indefinitely without causing damage.

Usage Features:

The Battery Tender® Plus is designed for ease of use with several practical features:

• Automatic Operation: Once connected, the charger automatically manages the charging process, eliminating the need for manual intervention.
• Spark-Free Connection: A key safety feature is its spark-free circuitry. The output alligator clips or ring terminals will not generate a spark if they touch each other or if the AC power cord is plugged in before connecting to the battery. The charger only activates its output voltage when it detects a battery with at least 3 volts and correct polarity.
• Polarity Protection: If the charger is connected with reverse polarity (e.g., red clip to negative post, black clip to positive post), it will not generate an output voltage. Instead, the red and green indicator lights will flash alternately, signaling the incorrect connection.
• Status Indicator Lights: Two-colored status indicator lights provide visual feedback on the charger's operating mode and the battery's condition:
  • RED LIGHT FLASHING: Indicates that the charger has AC power and the microprocessor is functioning, but either the battery voltage is too low (less than 3 volts) or the connections are incorrect.
  • RED LIGHT ON STEADY: Shows that a battery is properly connected, and the charger is actively charging it (bulk or absorption mode). This light remains on until the charging stage is complete.
  • GREEN LIGHT FLASHING: Signifies that the battery is greater than 80% charged. The battery can be used if necessary, but it's recommended to continue charging until the green light is solid.
  • GREEN LIGHT ON STEADY: Indicates that the charge is complete, and the battery is fully maintained in storage/float mode. The battery can be returned to service or left connected indefinitely.
• Extension Cord Compatibility: While generally not recommended, if an extension cord is absolutely necessary, specific guidelines are provided for proper wire size and condition to ensure safe operation.
• Troubleshooting Checklist: The manual includes a checklist to help users diagnose common issues, such as lights not turning on, green light appearing immediately on a discharged battery, or the green light not coming on after charging.

Maintenance Features:

The Battery Tender® Plus is designed for minimal maintenance, but certain precautions are outlined to ensure its longevity and safe operation:

• Cord and Plug Integrity: Users are advised not to operate the charger with a damaged cord or plug, emphasizing immediate replacement if damage occurs.
• No Disassembly: The charger should not be disassembled by the user. Any service or repair should be performed by a qualified serviceman to prevent electric shock or fire risks.
• Cleaning and Maintenance: Before any maintenance or cleaning, the charger must be unplugged from the outlet to reduce the risk of electric shock.
• Environmental Protection: The charger should not be exposed to rain or snow. It should also be located away from the battery being charged to prevent corrosive gases from damaging the unit.
• Proper Storage: When not in use, the charger should be stored in a dry, protected environment.

The device also emphasizes general safety precautions when working with lead-acid batteries, including wearing eye and clothing protection, having fresh water and soap nearby for acid contact, and never smoking or allowing sparks near the battery. It also provides detailed instructions for connecting the charger to batteries both inside and outside a vehicle, highlighting the importance of proper grounding and polarity to prevent explosions.
