How long will the battery last and how many charge cycles should I expect?

This Li-ion pack is rated for up to approximately 500 recharge cycles under normal usage patterns. Actual longevity depends on charging habits, operating temperature and workload; light use and moderate charging preserve capacity longer.

• Rated capacity: 48Wh at 15.2V for a balance of runtime and portability.
• Expect up to ~500 cycles before noticeable capacity loss under typical conditions.
• Battery life varies by applications: video, gaming and heavy CPU tasks reduce runtime compared with web browsing or document editing.

What installation and first-use steps help maximize performance?

Install the new pack securely, making sure contacts and screws are correct for your model. For first use, perform the recommended discharge/charge cycles to condition the battery’s controller and help the state-of-charge reporting become more accurate.

• First-use routine: discharge to about 5% (do not reach 0%), then charge to 95%; repeat 3–4 times.
• Use the original AC adapter or an equivalent charger matching laptop specs to avoid charging issues.
• Avoid extreme temperatures; store partially charged if not using the laptop long-term.

What safety and quality features does this RDSJ battery include?

The battery is manufactured to typical Li-ion safety and quality standards and includes protection circuitry to prevent overcharge, over-discharge and short circuits. It ships new from the factory and is intended as a direct replacement for worn packs.

• Protection circuitry built into the pack for safer charging and discharging.
• Manufactured new (not refurbished) to ensure consistent cell performance and cycle life.
• Follow local disposal and recycling rules for end-of-life batteries.
