IMPORTANT: read and save this safety and instruction manual. 1. IMPORTANT SAFETY INSTRUCTIONS 1.1 SAVE THESE INSTRUCTIONS – This manual contains important safety and operating instructions. The DieHard model 71225 Manual Battery Charger, offers a wide range of features to accommodate the needs for home or light commercial use. This manual will show you how to use your charger safely and effectively. Please read and follow these instructions and precautions carefully. 1.
WARNING – RISK OF EXPLOSIVE GASES. WORKING IN 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 YOU FOLLOW THE INSTRUCTIONS EACH TIME YOU USE THE CHARGER. To reduce risk of battery explosion, follow these instructions and those published by battery manufacturer and manufacturer of any equipment you intend to use in vicinity of battery. Review cautionary marking on these products and on engine. 2.
3. PREPARING TO CHARGE 3.1 If necessary to remove battery from vehicle to charge, always remove grounded terminal from battery first. Make sure all accessories in the vehicle are off, so as not to cause an arc. 3.2 Be sure area around battery is well ventilated while battery is being charged. 3.3 Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes. 3.4 Add distilled water in each cell until battery acid reaches level specified by battery manufacturer.
. FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN vehicle A SPARK NEAR BATTERY MAY CAUSE BATTERY EXPLOSION. TO REDUCE RISK OF A SPARK NEAR BATTERY: NEGATIVE GROUNDED SYSTEM 6.1 Position AC and DC cords to reduce risk of damage by hood, door, or moving engine part. 6.2 Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons. 6.3 Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has larger diameter than NEGATIVE (NEG, N,–) post. 6.
. FOLLOW THESE STEPS WHEN BATTERY IS OUTSIDE VEHICLE. A SPARK NEAR THE BATTERY MAY CAUSE BATTERY EXPLOSION. TO REDUCE RISK OF A SPARK NEAR BATTERY: 7.1 Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has a larger diameter than NEGATIVE (NEG, N, –) post. 7.2 Attach at least a 24-inch-long 6-gauge (AWG) insulated battery cable to NEGATIVE (NEG, N, –) battery post. 7.3 Connect POSITIVE (RED) charger clip to POSITIVE (POS, P, +) post of battery. 7.
. 8.1 battery charging - ac connections For all grounded cord-connected battery chargers with an input rating less than 15 amperes and intended for use on a nominal 120-volt circuit: • This battery charger is for use on a nominal 120-volt circuit, and has a grounding plug that looks like the plug illustrated in sketch A in Figure 8.3.

.4 Clean and store the charger in a dry location. Note: During the starting sequence listed above, the charger is set to one of three states. 11.5 Engine Starting Notes: • Wait for cranking - The charger waits until the engine is actually being cranked before delivering 80 amps for engine start. The charger delivers charge at a rate of up to 12 amps while waiting and will reset if the engine is not cranked within 15 minutes.
aborted charge, either disconnect the battery or unplug the charger. 12.4 DESULFATION MODE: If a battery is left discharged for an extended period of time, it could become sulfated and not accept a normal charge. If the charger detects a sulfated battery, the charger will switch to a special mode of operation designed for such batteries. Activation of the special desulfation mode is indicated by the CHARGING (yellow) LED blinking. If successful, normal charging will resume after the battery is desulfated.

may or may not have vent caps. Vent caps are located on top of the battery and provide a means to add distilled water when needed. Batteries should be marked with their type. If charging a battery that is not marked, check the manual of the item that uses the battery. 13.3 CHARGE RATE BUTTON Use this button to set the maximum charge rate to one of the following: • 2A SLOW CHARGE RATE: Intended for charging small batteries such as those commonly used in garden tractors, snow mobiles and motorcycles.
14.2 TESTER AND CHARGER: When first turned on, the 71225 operates only as a tester, not as a charger. To continue to use it as only a tester, avoid pressing the charge rate button. Selecting a charge rate activates the battery charger and deactivates the tester. Pressing the CHARGE RATE button when the 80A Start LED is lit (except during the 180 second cool down) will shut off the charger and activate the tester. 14.
15.1 TESTING SEQUENCE There are three basic steps required to use the 71225 as an alternator tester. • Connect the charger battery clamps to the battery or charging system. • Connect the charger power cord to a 120V AC wall outlet. • Start the vehicle and turn on the vehicle’s headlights. Read the voltage on the digital display or press the display mode button to set the tester to Alternator % to read the voltage as a percent of charge. 15.
16.4 There are some important facts to keep in mind when charging a battery: • When the display indicates 77% charged, the battery has been charged enough to start most vehicles and has already been charged as much as by many other battery chargers. • When the display indicates 85% charged, the battery has already been charged at least as much as by most other battery chargers. • The battery % shown in tester mode is an estimate based on the battery voltage.
17.2 Reviving your battery: If you only wish to charge your battery enough to operate the vehicle, you don’t need to wait for the entire charging process. When the charger displays a battery % of 77 or more, the battery has usually been charged enough for the vehicle to start and operate normally. 17.3 Completing an interrupted charge: If the charging process has been interrupted and restarted after the charger displays a battery % of 85 or more, the charger could go straight to Maintain Mode.
20. troubleshooting PROBLEM POSSIBLE CAUSE SOLUTION The battery is connected and the charger is on, but isn’t charging. The charger is in tester mode, not charger mode. Press the CHARGE RATE button to activate charging and select a charge rate. Indicator lights are lit in an erratic manner not explained in the “Operating Instructions” section. You might have accidentally activated a special diagnostic mode.
