PLEASE READ all operation and safety precautions before using charger. Contact Schauer Battery Chargers
with any questions prior to operation.
The term battery will be used to reference a single battery or multiple battery pack connected in series or
parallel.
Caution! Safety precautions must be observed to avoid personal injury, electrical shock or battery explosion!
 Confirm proper application of charger and battery pack voltage (ie. 24 volt charger with 24 volt battery pack)
 Always check for proper electrolyte level in battery (do not overfill, acid may overflow during charging)
 Charger’s power switch should be Off and unplugged from AC outlet before connecting to battery
 Position charger as far from battery as DC cord will allow while charging. Hydrogen gas may escape from battery
during charging, do not position charger above or below battery while charging
 Plug charger into a grounded AC outlet
 Operate charger in an environment with proper ventilation
 Charger must not be operated in a damp or wet environment
 Use proper charge rate (amperage) for battery rated amp hour (Ah) capacity. Check with battery manufacturer
 Do Not charge a frozen battery
 Be sure your battery is not drawing any load from equipment or instruments when you are charging
o A current draw on the battery during charging may prohibit charger from switching into the
maintenance float mode, resulting in overcharging, gassing and low electrolyte levels. Contact
Schauer Chargers if your application involves a constant current draw for options.
This is a multi-stage automatic charger: Bulk charge → Absorption charge → Maintenance float
