Product Condition:
Warranty provided by ALLHDD.COM:
30 Days


The UF302 Dell 3.7v 7wh Li-Ion Battery is designed to be used with the Dell PowerEdge RAID Controller (PERC) 5i. Specifically, this battery is used to power the PERC 5i's cache memory in the event of a power failure, allowing the controller to save any cached data to disk and prevent data loss.

To ensure compatibility, it's important to check that the battery is the correct model for your particular PERC 5i controller. In addition, it's important to make sure that the battery is properly installed and connected to the controller, as a loose or improperly connected battery can cause issues with the controller's cache memory.

It's also worth noting that, like any battery, the UF302 Dell 3.7v 7wh Li-Ion Battery has a limited lifespan and will eventually need to be replaced. Dell recommends replacing the battery every two years to ensure optimal performance and data protection.

Capacity and Performance

The capacity and performance of the UF302 Dell 3.7V 7Wh Li-Ion battery for PERC 5i depends on several factors, including the age of the battery, how it has been used, and the conditions under which it is used. Here's a general overview of what to expect:

Capacity: The capacity of a battery refers to the amount of energy it can store and deliver over a single charge cycle. In the case of the UF302 battery, its capacity is 7 watt-hours (Wh). This means that, in theory, the battery can deliver 1 ampere (A) of current for 7 hours, or 7 amperes for 1 hour, before it is fully discharged. However, the actual capacity of the battery may be less than the rated capacity, especially if the battery is older or has been subjected to heavy use.

Performance: The performance of the UF302 battery refers to how well it delivers power to the PERC 5i card. The performance of the battery can be affected by a number of factors, including the load placed on the battery, the temperature of the battery, and the age of the battery. Generally speaking, the battery will perform best when it is new, and its performance will gradually degrade over time as it undergoes charge and discharge cycles.

In terms of the specific performance of the UF302 battery for the PERC 5i, it is designed to provide backup power to the card in the event of a power outage or other power-related issue. The battery allows the PERC 5i to continue functioning for a short period of time (typically several minutes) while data is saved to disk or other measures are taken to protect against data loss. The actual performance of the battery in this context will depend on the specific usage scenario, as well as the age and condition of the battery.

Charging and Discharging

The UF302 Dell 3.7V 7Wh Li-Ion battery is a rechargeable battery that is commonly used in the PERC 5i RAID controller card. Here's a brief explanation of the charging and discharging process for this battery:

Charging Process: When the battery is connected to a charger, the charging process begins. The charger sends a current to the battery, which causes the lithium ions to move from the cathode to the anode. This process is known as "charging." As the battery charges, the voltage across its terminals increases, and the current flowing into the battery decreases. The charger typically monitors the battery's voltage and current, and when it detects that the battery is fully charged, it stops charging the battery.

Discharging Process: When the battery is in use, the opposite process occurs. The battery's stored chemical energy is converted into electrical energy, which can be used to power the device. As the battery discharges, the voltage across its terminals decreases, and the current flowing out of the battery also decreases. The battery will continue to discharge until its voltage drops below a certain threshold, at which point the device may shut down or prompt the user to recharge the battery.

It's important to note that Li-Ion batteries like the UF302 should not be fully discharged if possible, as this can damage the battery and shorten its lifespan. It's also recommended to use a charger specifically designed for Li-Ion batteries, as using the wrong type of charger can also damage the battery.
