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)
  • If required, check for proper electrolyte level in battery (do not overfill, acid may overflow during charging)
  • 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 LED charging sequence indicator Lights:
Green LED: AC power connected and charger not connected to battery
Red LED: AC power connected, charger in Bulk / Absorption charge modes
Green LED: Battery charged, Charger in maintenance float mode
Flashing Red LED:
– Flashing Red LED after time of solid Red LED, Charger is finishing Absorption mode before Full Charge with Green LED
– Flashing Red Led when connected, Charger connected to a battery with too large of Ah capacity to properly charge
– Flashing Red LED when connected, Charger is connected to a dead or shorted cell battery
Caution! This charger is intended for use with rechargeable Lead Acid type battery only: Flooded, Gel, AGM, SLA, VRLA and SLI (starting / automobile). Use with any other type of battery may cause damage or explosion.

Charger is equipped with a final stage maintenance float mode. You may leave charger attached to the battery for prolong periods of time and it will not overcharge the  battery. Lead acid battery prefer to be in a charged state. It is recommended to charge your battery after each use. Leaving the charger attached in float mode will aid against  sulfation build-up on the battery’s lead plates and maintain battery in a ready state.
If AC power is interrupted by a power outage or other, the charger will resume its charge/maintenance cycle when AC power is restored.
Proper charge rate (charger amperage rating) must be used to prevent damage to battery. Contact battery manufacturer for recommended charge rate. For a single battery or  batteries connected in series (negative to positive), the battery amp hour (Ah) capacity is that of a single battery. For batteries connected in parallel (positive to positive and  negative to negative), the battery Ah capacity is cumulative of all battery’s Ah.
Only batteries of same Ah rating, size and condition/age should be connected in series or parallel. Combining batteries of different capacity, age or condition will result in an  unbalanced charging of individual batteries in the pack resulting in possible battery damage.
This 2 amp automatic charger with final maintenance float stage can be used as a maintainer on a larger capacity battery. Charger should be attached to a fully charged battery  for long-term battery maintenance.
Caution! Charger operation, connections and proper electrolyte level should be checked routinely.

Care of operation:

– Battery charger must only be used for the purpose specified by the manufacturer.
– Wear proper eye and clothing protection at all times
– Someone should be within range of your voice when working with a battery & charger
– Do not operate the battery charger if housing or cables are damaged.
– Lay cables in such a way they are not in risk of damage or tripping.
– Position charger on secure surface to avoid falling over, keep out of reach of children.
– Do Not smoke or exposed to spark or flame while charging
– Do not drop metal tools or personal items across battery terminals causing shorts or sparking
– A qualified person familiar with the risks involved must perform service or repair
