Origin laptop battery 42 Wh (3400 mAh, 11.4 V) for Dell – Origin Storage Dell BTRY 42WHR 3C LITH
Replacement laptop battery from Origin designed for Dell systems. This Lithium‑Ion battery provides 42 Wh (3400 mAh) capacity at a nominal voltage of 11.4 V and comes as a single black unit intended to restore mobile runtime in compatible Dell notebooks. The battery is a direct replacement option for users who need to recover everyday portability and maintain normal workflow without relying on mains power.
The battery offers a compact, lightweight design with a standard Lithium‑Ion chemistry that balances energy density and cycle life. With 42 Wh capacity and 11.4 V nominal voltage it is compatible with systems that require these electrical characteristics, enabling predictable runtime and straightforward swap-in replacement. The single-unit black housing simplifies installation and maintains the original appearance of the laptop.
Power down the laptop and disconnect the AC adapter. Remove the existing battery following the notebook manufacturer’s instructions, taking care to work on a non‑conductive, static‑free surface. Insert the replacement battery into the battery bay until it clicks into place and secure any latches. Reconnect the AC adapter and allow the battery to charge fully before first use to calibrate the charge indicator and optimize initial performance.
Store and use the battery at room temperature, avoiding prolonged exposure to high heat or moisture. For best long‑term performance, cycle the battery periodically: charge to full, then discharge to around 20–30% before recharging. Use the original or manufacturer‑approved AC adapter and follow the notebook maker’s safety guidelines for disposal and recycling.
