Battery DELL 5280 5290 5480 BTI 3DDDG
The BTI 3DDDG Battery is a replacement Lithium Polymer (LiPo) battery designed for Dell notebook models 5280, 5290 and 5480. Manufactured by Battery Technology, Inc. (BTI), it provides 3684 mAh capacity in a compact black housing and is intended to restore mobile power for compatible Dell laptops while incorporating standard safety and energy-management features used in BTI battery designs.
The battery uses Lithium Polymer chemistry for stable energy delivery and a slim form factor. With a rated capacity of 3684 mAh, it offers extended runtime compared with depleted or aged cells. BTI’s production and circuit-design expertise ensures compatibility, integrated safety protections and consistent manufacturing quality for this replacement battery.
Power down the laptop and disconnect any external power source. Remove the existing battery following the manufacturer’s service instructions for your Dell model, then install the BTI 3DDDG battery into the battery bay until it latches securely. Reconnect power and allow the new battery to charge fully before first use. Verify battery status in the operating system battery indicator and in BIOS/UEFI if applicable.
Charge the battery using the laptop’s original AC adapter or a compatible charger. Avoid exposing the battery to extreme temperatures, moisture or physical damage. For long-term storage, keep the battery at about 40–60% charge and store in a cool, dry place. Follow Dell’s service guidelines when removing or installing internal batteries to prevent damage.
