49Wh 11.1V Dell Laptop Battery
This 49Wh lithium-ion battery replaces Dell part numbers ALW14D-2728, 4728, 1728, 5828 and 5728. It is built for owners of compatible Dell notebooks who need a new power source because the original pack no longer holds a charge. The six-cell design fits the standard battery bay for these models. Buyers whose laptops use a different voltage or connector will not be able to use this unit.
CE and RoHS Certified Replacement
The battery carries CE and RoHS certification, confirming compliance with European safety and environmental standards. A one-year replacement warranty covers defects in materials or workmanship. No software, drivers or additional accessories are included in the package. The certifications and warranty terms do not alter the physical installation process or the electrical specifications of the pack.
Straightforward Swap With Visual Check
Installation consists of releasing the old pack and sliding this unit into the same bay until it clicks. The supplier advises comparing the replacement with photos of your original battery before fitting to confirm the connector orientation and case profile match. The most common issue is ordering the wrong part number for a visually similar but electrically different model.

Questions about this item
How many charge cycles can the 6-cell lithium-ion pack sustain before capacity drops noticeably?
The 6-cell lithium-ion pack is rated for typical lithium-ion cycle life; capacity will gradually decline after several hundred full cycles, at which point a replacement is recommended.
What is the first limit reached during continuous discharge — voltage sag or thermal throttle?
Under sustained load the 11.1 V pack will hit its low-voltage cut-off before thermal limits become an issue, so runtime ends when voltage drops to the protection threshold.
Does the battery run warm or draw extra power when the laptop is plugged in all day?
Once fully charged the pack stops accepting current, so it adds negligible heat and no measurable power draw while the laptop runs on AC power.
