This Origin BTI 72Wh battery uses lithium‑ion chemistry to deliver a balance of capacity and weight, offering up to 6490 mAh of charge storage in a 6‑cell configuration. It is a direct replacement option for compatible Fujitsu models and is supplied as a single unit in black housing.

Power the laptop off and disconnect the mains adapter before replacing the battery. Remove the existing battery following the laptop manufacturer's instructions, then insert the Origin BTI battery until it locks into place. Reconnect the mains adapter and charge the new battery fully before first use to ensure the battery management system recognises the cell pack. Use the laptop's power settings to monitor charge level and battery health during initial cycles.
Store and operate the battery within manufacturer-recommended temperature ranges. To prolong battery life, avoid deep discharges and long-term storage at full charge; if storing for extended periods, keep the battery at around 40–60% charge and check levels periodically. Use only the laptop's approved charger and follow Fujitsu guidelines for safe disposal or recycling of Li‑Ion batteries.
