Schumacher SS-15A3-OB User Manual

1

Working in the vicinity of a lead-acid battery is dangerous. Batteries generate explosive gases during normal 

battery operation. For this reason, it is of utmost importance that each time before using your charger, you 

read this manual and follow the instructions exactly. 
To reduce risk of battery explosion, follow these instructions and those published by the battery manufacturer 

of any equipment you intend to use in vicinity of battery. Review cautionary markings on these products and 

on engine.

1.  Before  you  use  your  battery  charger,  read  and  follow  all 

instructions and cautions printed on:

•  Battery Charger

•  Battery

•  Unit using battery

2.  Use battery charger on Flooded Wet Cell, Maintenance Free

and Starved Electrolyte batteries only. Charger is not intended

to supply power to low-voltage electrical system other than for 

charging and maintaining batteries.

 

WARNING: Do not use battery charger for charging dry-cell 

batteries  that  are  commonly  used  with  home  appliances. 

These batteries may burst and cause injury to persons and 

damage to property.

3.  Use only attachments recommended or sold by manufacturer.

Use  of  non-recommended  attachments  may  result  in  fire,

electric shock, or injury.

4.  When disconnecting the battery charger, pull by the plug not 

by the cord. Pulling on the cord may cause damage to cord 

or plug.

5.  Locate battery power cord so it cannot be stepped on, tripped 

over, or subjected to damage or stress.

6.  Do not operate charger with damaged cord or plug. Have cord 

replaced immediately.

7.  Do not operate charger if it has received a sharp blow, been 

dropped, or otherwise damaged in any way. Take it to a qua-

lified professional for inspection and repair.

8.  Do not disassemble charger. Take it to a qualified professional

when service or repair is required. Incorrect reassembly may 

result in electric shock or fire.

9.  To reduce risk of electric shock, unplug charger from outlet 

before attempting any maintenance or cleaning.

10.  Do not use an extension cord unless absolutely necessary. 

Use of an improper extension cord could result in fire or electric

shock. If an extension cord must be used, make sure that:

•  Pins on plug of extension cord are the same number, size,

and shape as those of plug on charger.

•  Extension  cord  is  properly  wired  and  in  good  electrical

condition.

•  Wire size is large enough for AC ampere rating of charger,

as specified below:

 

11.  Always charge battery in a well-ventilated area.

 

NEVER  operate  in  a  closed-in  or  restricted  area  without 

adequate ventilation. 

12.  Locate charger as far away from battery as DC charger cables

permit.

13. 

NEVER charge a frozen battery. If battery fluid (electrolyte) is

frozen, bring into a warm area to thaw before charging.

14. 

NEVER allow battery acid to drip on charger when reading 

specific gravity or filling battery.

 

WARNING:  Battery  chargers  get  hot  during  operation  and 

must  have  proper  ventilation. Air  needs  to  flow  around

the charger. Do not set on flammable items like carpeting,

upholstery, paper, cardboard, etc. Will damage leather and 

melt plastic and rubber.

WARNING: Handling the cord on this product or cords associated with accessories sold with this product, may expose you to lead, a 

chemical known to the State of California to cause cancer and birth defects or other reproductive harm. Wash hands after handling.
