Advantages by application
Valve regulated lead-acid batteries employ a lead-tin-calcium base alloy for their grids, and are designed with a structure that requires no water refilling, which allows them to support an information society relying on devices such as telecommunication equipment.
The batteries have high resistance to severe use conditions such as overcharging, over discharging, vibrations, and impacts, and also possess excellent storage characteristics. Panasonic offers a product lineup that enables customers to use our batteries for a wide range of applications such as in UPSs, power tools, and electric cars and tricycles.
We also have been proactively tackling the development of products including a trickle/cycle long life type battery based on the technologies that we accumulated over many years of development to promptly respond to market demand.
|Base Station, CATV,
for Backup Power Supply
|These are long life batteries for trickle charge applications. They were developed to achieve the same dimensions as previous products through multifaceted examinations and analyses of the cause of battery degradation.
Both the standard series (LC-V) and long life series (LC-P) use a flame-retardant battery container, thereby improving their safety and reliability.
|TRICKLE STANDARD TYPE (LC-V)
TRICKLE LONG LIFE TYPE (LC-P)
Rail Transit, etc.
for Backup Power Supply
|The use of a solid plate structure and flame-retardant battery container enables long-term use.||TRICKLE SUPER LONG LIFE TYPE (LC-QA)|
UPS, PBX, etc.
|Power supplies for business use that continue to increase with the proliferation of computers.
The batteries use a flame-retardant battery container and reliably backup the power of computers.
(1) Excellent high rate discharge capacity
(2) Downsizing design
(3) High energy density (typical example: approx. 30% improvement compared to previous products)
|HIGH POWER TYPE FOR STANDBY POWER (UP-)|
Electric cars and tricycles,
Power Tool, etc.
for Main Power Supply
|These are long life batteries for cycle applications developed in response to customer demand for reducing the number of battery replacements.
The batteries have low self-discharge with a structure to prevent leakage.
|CYCLE STANDARD TYPE (LC-R)
CYCLE LONG LIFE TYPE (LC-XC)
|Solar Energy||These batteries employ Panasonic’s EV cycle technology and are best suited to the storage of electricity for photovoltaic power generation.||SOLAR ENERGY TYPE (LC-T)|
Pitch Backup Systems
|This is a battery specifically designed for the backup systems of wind turbine pitch controllers.||FOR PITCH BACKUP SYSTEMS IN WIND TURBINE (LC-WT)|
About the selection of a battery
Technical requirements for selecting a battery
* Investigation of the requirement specifications (draft): Guidelines to select the most suitable storage battery for the equipment used
By comparing the requirements and use conditions when operating a storage battery to the battery selection criteria, please investigate and create the requirement specifications (draft) for your target storage battery.
For your reference, the following summarizes technical requirements for selecting a battery.
【Technical requirements for selecting a battery】
■ Storage battery selection
Narrow down potential batteries for the selection to a few types of batteries based on information such as catalogs and data books. Among these batteries, please select one that can meet the ideal level of requirements as much as possible.
Practically, there are few instances in which you can select a satisfactory battery as mentioned above. Therefore, the following should constitute basic procedures: Investigate whether some items in the requirement specifications (draft) can be omitted or relaxed, and then select a battery currently in production and sold on the market under the conditions. This type of investigation allows you to economically select a battery. If you have any questions at this step, then please lodge a detailed inquiry with a battery engineer. There may be cases where we can meet your requirements through the improvement or development of our batteries. Usually, requirement specifications are also determined during this step.
■ Demand for the improvement or development of storage batteries
If you cannot find a battery that meets your requirements under necessary and special operating conditions through the selection procedures described on the left, then you should request our technical department to improve an existing model or develop a new one. This case requires us to allocate a period of investigation. Therefore, please send us a request as soon as possible. We usually require at least 6 to 12 months for such an investigation, which is handled case by case depending on the details.
If you need more detailed information with regard to the selection of a storage battery, then please contact our company.
If a battery is used under charging and discharging conditions that exceed our recommended range, then this can result in shorter battery life and other forms of degradation. Please thoroughly investigate your selection based on your actual loading patterns and use conditions after checking the characteristics of our batteries given in a separate section. Please check the delivery specifications for details.
