First Impressions: This Turpow battery arrived in plain packaging but felt sturdy. Installation was a breeze—just four screws and it snapped into my Roomba 650 like OEM. The included brushes were a nice touch for maintenance.

Performance: My old battery barely lasted 15 minutes. With this 5000mAh upgrade, I’m getting 55-60 minutes of runtime—enough to clean my 800 sq ft apartment without mid-cycle charging. It’s not quite the 90 mins of a brand-new Roomba, but for a 5-year-old vacuum, it’s a game-changer.

Real-World Test: Ran it daily for a week on mixed surfaces (hardwood + medium-pile rug). Consistent performance, though runtime dropped by ~5 mins by day 7. The battery stays cool during charging—no overheating worries.

Pros: - Value: Priced 40% lower than iRobot’s battery - Safety: CE/FCC certified with overcharge protection - Compatibility: Works across 20+ Roomba models (tested on 650 & 780) - Warranty: 1-year replacement guarantee

Cons: - Longevity: Some users report needing replacement after 8-12 months - Capacity Variance: My unit showed 4800mAh when tested, not the advertised 5000mAh - Charging Time: Takes 4+ hours for full charge (original: 3 hrs)

Verdict: Perfect for reviving older Roombas or as a backup battery. While it won’t match OEM lifespan, the price-to-performance ratio makes it a smart buy. Tip: Do a full discharge/charge cycle every 2 weeks to maintain capacity.
