PLEASE READ all operation and safety precautions before using the charger. Contact Schauer Battery Chargers with any questions before 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!

• For use with 115 Volts AC mains electrical service: USA, Canada. (220/240 VAC conversion available. Cut “115 Jump” wire on the circuit board’s AC end. Contact Schauer Chargers for additional information)
• Confirm proper application of charger and battery pack voltage (i.e. 24-volt charger with 24-volt battery pack)
• If required, check for proper electrolyte level in the battery (do not overfill, acid as it may overflow during charging)
• The charger’s power switch should be Off and unplugged from AC outlet before connecting to the battery
• Position the charger as far from the battery as the DC cord will allow while charging. Hydrogen gas may escape from the battery during charging, do not position the charger above or below the battery while charging
  Plug the charger into a grounded AC outlet
• Operate the charger in an environment with proper ventilation
• The 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 the battery manufacturer
• Be sure your battery is not drawing a constant load from equipment or instruments when you are charging
  •  A constant current draw on the battery during charging may prohibit the 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: (On the end plate near the AC power cord and fuse holder)
LED1 (Left): Red – AC power connected, Power switch On
LED2 (Right): Green – Charger Not Connected / No Load, Connected and minimum battery voltage not sensed or
Output Fuse blown
LED2 (Right): Amber – Charging, Bulk, and Absorption stages- Fan On
LED2 (Right): Green – Battery charged, Charger in maintenance float mode, Fan Off

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 Safety Features:

• Reverse Polarity protection
• Short Circuit Protection
• Cooling Fan
• Low voltage turn-on (load sensing)
  •.  The charger requires a minimum battery voltage to begin the charging cycle. This protects against trying to charge a dead or shorted battery. Lower LED would remain off when connected. The minimum voltage is 1/3 charger rated voltage (for example 24-volt charger, the minimum battery voltage requirement is 8 volts)The charger is equipped with a final-stage maintenance float mode. You may leave the charger attached to the battery for prolonged periods of time, and it will not overcharge the battery. Lead acid batteries 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 the battery in a ready state.

  When the charger is turned off, the LED lights may flash for several seconds as power dissipates from the charger. If AC power is interrupted by a power outage or other, the charger will resume its charge/maintenance cycle when AC power is restored.

  A proper charge rate (charger amperage rating) must be used to prevent damage to the battery. Contact the 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 the 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.

Caution! Charger operation, connections, and proper electrolyte level should be checked routinely.

Proper electrolyte levels for Flooded (Wet), non-maintenance free sealed batteries:

Note: Use distilled/purified water only, unfiltered tap water contains minerals and may cause build up on the lead plates of the battery.

Confirm the correct electrolyte level per your battery’s manufacturer instructions. Check electrolyte level routinely to avoid exposing lead plates to air; this may cause irreparable damage due to oxidation to the lead plates reducing the battery’s capacity. Do not fill to correct level prior to charging; this may cause overflow during charging. It is best to fill the battery several hours after the charge cycle when the battery has cooled down. If top of plates are exposed before charging, only add enough water to cover the top of the plates; top off level after charge cycle and batteries have cooled down. Electrolyte gassing (bubbling) towards the end of charge cycle is beneficial for the health of the battery. It keeps the electrolyte from stratifying and condensing in the lower portion of the battery causing uneven charging of the plates. Prolonged gassing will lower electrolyte level.

DC Output protection fuse:
If the charger does not initialize charging (Yellow LED2) and LED2 remains Green when connected to a known discharged battery, check the fuse under the twist cap. Use correct replacement fuse. Size: 5mmx 20mm, fast-acting. Note the correct amperage of the fuse for the charge rate (amperage) charger model in use.

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

Caution! If you have any questions about proper charger application, contact Schauer Battery Chargers before connecting or attempting to operate charger.
