IMPORTANT SAFETY INSTRUCTIONS
WARNING - BURST HAZARD
Do not use the unit for charging dry-cell batteries that are commonly used with home appliances. These batteries may burst and
cause injury to persons and damage property. Use the unit for charging/boosting a LEAD-ACID battery only.
WARNING - SHOCK HAZARD
• Do not operate unit with damaged cord or plug; or if the unit has received a sharp blow, been dropped, or otherwise
damaged in any way. Do not disassemble the unit; incorrect reassembly may result in a risk of electric shock or fire.
• NEVER submerge this unit in water; do not expose it to rain, snow or use when wet.
• To reduce risk of electric shock, disconnect the unit from any power source before attempting maintenance or cleaning.
WARNING - RISK OF EXPLOSIVE GASES:
• Working in the vicinity of a lead acid battery is dangerous. Batteries generate explosive gases during normal battery
operation.
• If battery acid contacts skin or clothing, wash immediately with soap and water for at least 10 minutes and get medical
attention immediately.
• Do not operate this unit in a closed area or restrict ventilation in any way.

12V battery recovery:
•
For 12V batteries voltage lower than 8V, you can use the charger to recover the battery.
Recovery Operation Steps:
1. Plug in the AC power without the connection with the battery;
2. Press the MODE button for 3~5 seconds until the 12V LED indicator comes on;
3. Now connect the output clamps/terminal rings with the battery correctly or use cigarette
lighter adapter. Cigarette lighter of accessory socket must be live with car off to work.
4. The charger begins charging with 1.5A low current to recover the battery, which terminates when the voltage reaches to
10.5V ± 0.25V, and then it switches over to regular charging mode.
OPERATING INSTRUCTIONS
1. Connecting the terminal rings/clamps directly to the corresponding connectors on the battery posts.
Note: Make sure correct polarity connection before plugging in the AC power.
• Position the RED terminal on the POSITIVE post connector
• Position the BLACK terminal on the NEGATIVE post connector

Questions and answers
Good morning, I have a Schwann automatic battery charger for charging small 12 volt batteries. Recently I connected it to a new battery to verify the charger and it flashes as a bad battery, I checked the voltage of the battery with a meter and it reads 12 volts. I even tried the recovery step on the charger that turns the charger on at 12 volts at 1.5A. This step is supposed to revert back to the regular charging mode once the charger senses 10.25-10.75 volts but it doesn’t. Is the charger bad?
If the Schwaben automatic battery charger indicates a bad battery despite the battery reading 12 volts, it does not necessarily mean the charger is faulty. The charger determines battery health based on more than just voltage; it may also assess the battery's ability to hold a charge or detect internal issues. A battery can read 12 volts but still be defective due to factors like high internal resistance or insufficient capacity. If the charger consistently shows a bad battery indicator, testing the battery under load or with another charger may help confirm its condition.
