LC-XC1238 SPECIFICATIONS FOR THE RECHARGEABLE VALVE REGULATED LEAD-ACID BATTERY Model No. LC-XC1238P 1. Scope These specifications pertain to Panasonic Storage Battery (Shenyang) Co.,Ltd.`s (PSBS`S) Rechargeable Valve Regulated Lead-Acid Battery, type LC-XC1238P, hereafter referred to as the “battery”. This document only describes the performance of the battery. The price, delivery date and other matters should be dealt with in other mutual agreements. 2.
LC-XC1238 discharge cycle (about less than 30% of rated capacity). Please contact Panasonic office. 4.4 Over-discharge Recovery Characteristics This refers to the percent of capacity that can be recovered after remaining in a prolonged discharged condition. Test procedure( Ambient temperature of 25±2℃) (1) Connect the battery to a 1.26Ωresistor for 24 hours. (2) Disconnect the resistor and stand for one month. (3) Charge the battery for 24 hours with the specified charger then stand for one hour.
LC-XC1238 Ambient Temperature 0℃ 25℃ 40℃ Charge Voltage(a) 15.2 to 15.6V 14.5 to 14.9V 14.0 to 14.4V Cycle Type(b) Notes: (a) Charge voltage refers to the voltage remaining at the end of charge. (b) For cycle type batteries, the time required to complete each charge depends on the discharged condition of the battery, characteristics of the charger used, and the temperature during charge. The time required can be estimated using the following expression: (1) If the discharge current is larger than 0.

Environments and Conditions Installation Preparation Prior to Operation Unspecified Use Methods of Handling and Operation Maintenance Treatment at Emergencies Storage Disposal and Recycling ________________________________________________________________ 1. Environments and conditions Danger (1) Do not put the batteries into airtight containers or bags.
get wet, they may corrode. (4) Do not use or store the batteries in a car under the blazing sun, in direct sunlight. To do so may cause the batteries to leak, generate excessive heat, or explode. (5) Do not use or store the batteries in a dusty place as dust may cause them to short between their terminals. When using the batteries in a dusty place, check them periodically.
(3) Do not install the batteries in areas where they may come in contact with water. If the batteries come in contact with water, an electric shock or fire may occur. Caution (1) During unpacking, handle the batteries carefully and check for cracks, breakage, or electrolyte leakage. Failure to handle carefully may result in damage due to physical shock. (2) When the batteries are being mounted in the equipment, consider the best position for easy checking, maintenance and replace ability.
(7) Fasten the bolts and the nuts with the torque as shown below: Not to do so may cause the battery terminals to spark and/or break. Diameter Bolt (Nut) Size Pitch Length Fastening torque M5(5mm) 0.8mm 15±1mm 1.96~2.94N • m M6(6mm) 1.0mm 20±1mm 3.92~5.39N • m M8(8mm) 1.25mm 20±1mm 7.84~9.80N • m M10(10mm) 1.5mm 36±1mm 14.70~19.60N • m (8) Place the necessary insulating covers over the terminals, the connecting bars, and bolts and nuts to prevent a dangerous electric shock.
Below 20℃ :9 months Below 20-30℃ :6 months Below 30-40℃: 3 months Charge method Constant voltage Constant current Charging condition (at 77℉,25℃) *Regulation range of the controlled voltage: 7.25V to 7.45V/6V battery, 14.5V to 14.9V/12V battery; Initial current:0.1CA to 0.4CA; Maximum charging time: 24hours. *Short-time charge is possible when several batteries of the same model, under the same storage conditions can be charged in series. Otherwise they can be charged separately. *Charging current:0.
(1) To prevent accidents from happening, change any battery that is found to have an abnormality such as crack, deformity, or leakage. The batteries must be kept clean and free from dust to prevent loss of capacity or accident. (2) If any abnormality of the charge voltage or the discharge voltage is detected, replace the batteries with new ones. (3) Charging the batteries with an inverse polarity connection between the batteries and the charger could cause electrolyte leakage, heat generation, or a fire.
(5) Switch off the equipment after use to prevent loss of performance or shortened life of the batteries due to damage over-discharges. (6) When storing the batteries, be sure to remove them from the equipment or disconnect them from the charger and the load to prevent over-discharge and loss of capacity. Before storing batteries, charge the batteries fully. Do not store batteries in a highly humid place to prevent rust from forming on the terminals. 6.
Caution (1) Store the batteries in a fixed position separate from metal or other conductive materials. (2) Keep the batteries from rainwater that could cause corrosion on the terminals of the batteries. (3) Keep the batteries right side up during transportation and do not give any abnormally strong shock and jolt to the batteries. Transporting the batteries in an abnormal position or handling them roughly could destroy the batteries or cause their characteristics to deteriorate.
