BatteryMINDer® Models 12248 & 24041 h. Use charger for charging a LEAD-ACID battery only. It is not intended to supply power to a low voltage electrical system other than in a starter-motor application. 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. i. NEVER charge a frozen battery or a battery at a temperature above 123° F. 13. PREPARING TO CHARGE a.
BatteryMINDer® Models 12248 & 24041 15. DC CONNECTION PRECAUTIONS a. Connect and disconnect DC output clips only after setting any charger switches to “off” position and removing ac cord from electric outlet. Never allow clips to touch each other. b. Attach clips to battery and chassis as indicated in 15(e), 15(f), and 16(b) through 16(d). 16. 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: a.
BatteryMINDer® f. g. Models 12248 & 24041 When disconnecting charger, always do so in reverse sequence of connecting procedure and break first connection while as far away from battery as practical. A marine (boat) battery must be removed and charged on shore. To charge it on board requires equipment specially designed for marine use. QUALIFYING YOUR BATTERY: Preliminary Requirements NOTE: The BatteryMINDer has no electrical output unless it is connected to a healthy battery.
BatteryMINDer® Models 12248 & 24041 and completely charged before you determine its condition. Allow battery to “rest” (see Glossary of Terms) overnight for a minimum of 12 hours before testing with a temperature compensated hydrometer and/or digital type voltmeter only. Specific Gravity – Capacity Temperature Compensated Hydrometer - Meter or 4 ball type Full Capacity Percentage 1.270 (4 Balls floating) 100% 1.250 (3 Balls floating) 75% 1.190 (2 Balls floating) 50% 1.
BatteryMINDer® Models 12248 & 24041 Testing with a Hot/Cold Calibrated Hydrometer Tester Read the tester instructions carefully for most accurate readings. 1. When using the tester the first time or after a long period of non-use, fill the tester with the battery fluid and let it sit for 1/2 hour or longer. This will soak the balls in order to give you more accurate readings.
BatteryMINDer® Models 12248 & 24041 3. Connect the BatteryMINDer to the battery. 4. Charge battery to its maximum level. Allow battery to remain for a minimum of 72 hours before retesting. If improvement is seen, continue until battery voltage reaches full capacity level or no further increase is seen.
