SPECIFICATIONS FOR THE RECHARGEABLE VALVE REGULATED (SEALED) LEAD-ACID BATTERY Model No. LC-XD1217P
1.
Scope
These specifications pertain to Shenyang Matsushita Lead-Acid Battery Co.,Ltd.s ( SLMBS) Rechargeable Valve Regulated (Sealed) Lead-Acid Battery, type LC-XD1217P, 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.
Requirements
Voltage, capacity, mass and dimensions for this model are shown in Table1. Table 1 requirements Model Nominal Voltage Rated Capacity at 20hour-rate(Ah) Mass(approx. Kg) Dimensions
3.
LC-XD1217P 12V 17 6.5 shown in the attached drawing
Structure
The battery consists mainly of positive plates, negative plates, separators, electrolyte, valves, a container and a cover. The electrolyte is absorbed in both positive/negative plate and separators.
4.
Characteristics
The following characteristics are for the batteries, which are manufactured within 6 months, independently.
4.1 Capacity
If the battery is discharged at 4.25A to the end voltage of 10.5V per battery after a full charge, followed by standing of one hour at an ambient temperature of 252? , the discharge duration time should exceed 3 hours within the first 3 times of the charge and discharge cycles. 4.2 Shelf life characteristics The duration time should be more than 80 minutes when the battery, which has been stored at an ambient temperature of 402? for 4 months, then stored at an ambient temperature of 252? for 24 hours and is then discharged at 4.25A to the end voltage of 10.5V per battery.
4.3 Trickle life
If the battery is fully charged with a constant voltage charger with the controlled voltage of 13.7 0. 10V at an ambient temperature of 252? , and every 3 months the battery is discharged at a constant current of 4.25A to 10.5V at an ambient temperature of 252? , the battery shall have a trickle life of over 3 years with a discharge duration of over 1.5hours. ( Expected design life with trickle: More than 10 years when discharging 0.25CA at 20C ) Note: the expected life of the battery shall decrease by one -half with each rise in temperature of 10? . In particular, the life of the battery will shorten remarkably at about 40? . Therefore careful consideration must be taken not to use the battery at high temperature. Also, as mentioned in 4.3 above, the life of battery will vary depending on the charge/discharge conditions. For example, a non-flat current may shorten the life of the battery. Thus if special charge and/or

discharge methods not described in this specification will be used, please confirm the battery characteristics with the actual application equipment before designing the charger. As the period of use of VRLA (SLA) battery becomes longer, the run time of the battery gradually becomes shortened. While the battery reaches the end of life with the shortened run time, such phenomena as gradual decrease of electrolyte and corrosion of the positive grid occur inside of the battery. If the battery of this condition continues to be used, it may suffer from thermal runaway (a vicious circle of increasing charge current and rising temperature) and electrolyte leakage as its capacity reaches 0. We strongly recommend taking proper preventive measures such as replacing batteries before any of these phenomena are found. In addition, if the case is made of metal, please be sure that the battery is insulated against its metal case with acid-and heat-resistant insulating material so that the battery can not touch the metal case directly. If the battery continues to be used without proper replacement, or if it is not insulated properly, it may generate fire. In case you can not replace batteries for some serious reason, please take some other preventive actions such as stopping charging. Please see `Recommended timing for battery replacement for backup applications' for more detailed information.
4.4 Vibration Resistance Characteristics
Vibration resistance characteristics are tested such that a fully charged battery, being in a right side up position, is subjected to vibrations under the conditions given below. The battery is then checked visually for damage such as deformation or leakage of electrolyte, and checked electronically for existence of a short circuit or the terminal voltage being lower than the nominal voltage. (1) Direction of vibration (2) Peak to peak Amplitude (3) Vibration Frequency (4) Duration of Vibration (5) Ambient temperature Vertical 4 mm 16.7Hz Continuously for 1 hour 252? throughout the test
Note: The battery being tested must be firmly fixed on the vibration board.

Limited Warranty
The following limitations apply to SLMBS warranty:
(1) The battery is covered by warranty for a period of 1 year from the date of production if
defective materials or production mistakes originating from SLMB are the cause of any battery problem. (2) The warranty limits SLMB to supplying a new battery to replace the defective battery. (3) The warranty does not apply if the problem has been caused by one of the following: (a) The battery has been used for purposes not specified by SLMB; or (b) The battery has been modified in any way. (4) If the cause of the problem is not clear, SLMB reserves the right to investigate the actual application in which the battery was subjected.
