Morpilot 3200mAh Replacement Battery for Shark RVBAT850 - Long Run

In this review of the Morpilot 3200mAh replacement battery for Shark RVBAT850, the bottom line is simple: it is a practical, low-cost replacement for owners of supported Shark Ion robot vacuums who need restored runtime without buying a new robot. The reviewer found the battery delivers the expected capacity and fits the machines that require a 2-prong connector, making installation straightforward. The most convincing reason to buy is the combination of a true RVBAT850 model match and a clear 2-prong plug confirmation, which avoids the common mistake of ordering a 3-prong battery that will not fit.

Key Features

• Model match: This battery is the specified RVBAT850 replacement, so it fits vacuums that list that model for compatibility.
• Connector type: The two-prong connector is explicitly confirmed, preventing the common mismatch with three-prong models.
• Capacity and runtime: At 3200mAh and 14.4V, a full charge commonly delivers about 150 to 200 minutes of cleaning time depending on the robot model and battery age.
• Fast, compatible charging: Works with the original charging station and typically reaches full charge in around 3.5 hours.
• Safety features: Built-in protections guard against overcharge, over discharge, over current, and short circuit for safer use in the robot.
• Form factor: Same size and function as the original battery, making installation easy and secure.

Who It's For

This battery is best for owners of Shark Ion models that explicitly use the RVBAT850 battery and a 2-prong connector, including RV700_N, RV720_N, RV725_N, RV750_N variants and a range of R75, R85 and RV850-series robots. It is a sensible replacement for someone who wants a cost-effective way to restore run time and expects similar performance to the original cell.

Shoppers who should look elsewhere include anyone with a Shark Ion model that lacks the _N suffix (for example RV700, RV720, RV750, RV755) or machines that require a 3-prong connector; this battery will not fit those robots. Also, users seeking OEM branding may prefer an original manufacturer part instead of a third-party replacement.

Pros & Cons

Pros

• Correct RVBAT850 model and 2-prong connector listed so buyers can avoid a mismatched purchase.
• Good runtime for the capacity, with many users reporting 150mins or more on a full charge.
• Easy installation and physical compatibility with the original battery compartment.
• Affordable alternative to a full robot replacement while restoring cleaning performance.

Cons

• Some users report mixed opinions on long-term battery life compared with original cells, so longevity may vary by usage and machine age.
• Not compatible with Shark models that use a 3-prong connector; check the model suffix carefully before buying.
