Battery Capacity and Voltage
Battery capacity refers to the amount of energy that a battery can store and deliver to a device over a certain period of time. The capacity is measured in milliampere-hours (mAh) and it represents the amount of current a battery can provide for one hour.
The HPE 4.8v Ni-mh 650mah Low Profile Battery (part number 453779-001) has a capacity of 650mAh. This means it can provide 650 milliamperes of current for one hour, or 325 milliamperes for two hours, and so on. It is a nickel-metal hydride (Ni-MH) type of battery that is designed to provide power to the Smart Array P400 and P700 controllers.
The voltage of the battery is 4.8V. Voltage is the electrical force that pushes the current through a circuit. It is important to match the voltage of the battery to the device’s voltage requirement in order to ensure proper operation. A battery with too high or too low voltage will not work correctly with the device and may even cause damage.
It’s worth noting that the capacity of a battery is not an exact value and it can vary depending on the usage and the environment. Over time, batteries lose their ability to hold a charge and the capacity decreases. It is important to monitor the battery charge level to ensure that it is charged and maintained properly to prolong its life.
Compatibility with the Smart Array
The HPE 4.8v Ni-mh 650mah Low Profile Battery (part number 453779-001) is specifically designed for use with the HP Smart Array P400 and P700 controllers. These are high-performance storage controllers that are commonly used in servers and other data center equipment.
The Smart Array P400 and P700 controllers are designed to provide advanced data protection and performance features for storage arrays. They use batteries as a backup power source to maintain data integrity and consistency in the event of a power failure. The 453779-001 HPE battery is designed to provide the necessary power to the controller during a power failure and also to protect the data stored in the controller’s cache memory.
It’s important to use only original and compatible batteries with the Smart Array P400 and P700 controllers to ensure proper operation and to maintain the warranty of the device. Using non-compatible batteries can cause damage to the controller and also void the warranty of the device.
It’s always recommended to check the compatibility of the battery with the specific model of the Smart Array controller before purchasing to ensure it will work properly.
Installation and Maintenance
The installation and maintenance of the HPE 4.8v Ni-mh 650mah Low Profile Battery (part number 453779-001) is relatively simple. The battery is designed to be easily replaced by authorized service providers or advanced users.
Here are some general guidelines for installing and maintaining the battery:
Installation:
- Turn off the server and disconnect all cables.
- Remove the battery compartment cover.
- Remove the old battery and disconnect it from the controller.
- Install the new battery and connect it to the controller.
- Replace the battery compartment cover.
- Turn on the server and check the battery status in the controller’s firmware.
Maintenance:
- Keep the battery in a cool, dry place. Avoid storing it in extreme temperatures or in direct sunlight.
- Charge the battery before use.
- Check the battery status regularly.
- Replace the battery if it fails to hold a charge or if it reaches the end of its service life.
- Always use the compatible and original battery for the Smart Array controller to maintain the warranty of the device.
It’s worth noting that the service life of the battery can vary depending on usage and the environment. It is important to monitor the battery charge level to ensure that it is charged and maintained properly to prolong its life.
