3300mAh Replacement Battery for iRobot Roomba 500-900 Series - Long

In this review of the VANPIR 3300mAh replacement battery, the bottom line is simple: it is a cost-effective upgrade for owners of many Roomba models who need restored runtime and reliable daily use. This reviewer found it best for users with 500, 600, 700, 800 and 900 series machines where the original pack has degraded; the battery's higher 3300mAh capacity and Li-ion construction are the single biggest reasons to buy, offering longer run times and lower self-discharge than older Ni-MH packs.

Key Features

• Wide compatibility: Fits a long list of Roomba 500, 600, 700, 800 and 900 series models so many owners can replace a worn pack without model hunting.
• Higher capacity: The 3300mAh (48Wh) rating delivers noticeably longer runtime compared with many older replacement cells rated lower in mAh.
• Li-ion chemistry: Low self-discharge of about 1% per month helps the battery hold charge during periods of infrequent use.
• Durability: Constructed from premium cells designed to retain about 80% capacity after extended cycles for long-term value.
• Safety certifications: CE, FCC and RoHS certified, giving confidence in compliance and stable current delivery during normal operation.

Who It's For

This battery is best for Roomba owners whose original battery shows reduced runtime, frequent docking during cleaning, or inability to complete a cleaning cycle. It is especially appropriate for people who want a higher capacity Li-ion alternative to older Ni-MH packs and who run models in the 500 through 900 series list including common 960, 870, 650 and 560 variants.

It is not for Roomba models outside the listed compatibility, and some users with very new or uncommon docking systems should check charging behavior: if a robot uses a third-party dock, take care the Roomba never fully drains below recommended levels or the pack may be damaged.

Pros & Cons

Pros

• Compatible with many Roomba series, making it easy to replace worn batteries across several models.
• Higher 3300mAh capacity and Li-ion cells typically yield longer run time and lower self-discharge.
• Safety certifications and claimed durability provide assurance for daily household use.

Cons

• Some users report compatibility issues with a few robots or third-party docks, so double-check your model before buying.
