Frequently Asked by Distributors:
Does the I7 fit the iRobot Roomba i7, i8 and E5?
Yes, the i7 is a direct replacement for the i7, i8, and E5 (7150 and 7550) robot vacuums made by iRobot. It is a true 14.4V 2.5Ah cartridge pack that fits the vacuums exactly.
What is the MOQ for the I7 replacement battery?
The standard MOQ is 100 units for the I7. You can get paid samples of 1–10 units to make sure they fit and to validate the BMS-handshake before placing an order for production. Private-label or custom-spec runs start at 500 units.
Is the I7 drop-in compatible with the original iRobot charger or dock?
Yes, the i7 BMS is updated with software designed specifically for that model. This ensures that it charges and reports correctly on the real iRobot charger. It also makes sure that the state-of-charge, authentication, and safety lockouts behave like the OEM iRobot Roomba i7/i8 pack. It is checked and approved for 100% of the units at the end of the production line.
How do I replace the battery in my iRobot Roomba i7 / i8?
Replacing the iRobot Roomba i7/i8 battery is easy. First, power off the robot vacuum. Next, release the battery latch or clip. Then, remove the old battery pack and fit the i7 until it seats properly. You don’t need any tools or modifications. It charges on your iRobot charger or dock.
How long does the I7 battery last per charge?
The I7 delivers a true 2.5Ah at 14.4V, matching or exceeding the runtime of the original pack. How long the device lasts depends on the power mode and the accessory. The cells are matched and aged so that the pack will have the same capacity for its full cycle life.
Why is my iRobot battery not charging or not holding charge — does a replacement fix it?
If your battery pack won’t hold a charge or charge properly, it’s likely that the batteries are nearing the end of their lifespan or the battery management system (BMS) has malfunctioned. A new I7 with fresh Grade-A cells and a fresh BMS solves the “not charging” and “not holding charge” problems caused by a worn-out original pack.
Are these genuine Philips batteries or replacements?
The I7 is a high-quality aftermarket replacement, not an OEM iRobot-branded pack. It is built with high-quality cells, a custom battery management system, and is designed to fit specific models of iRobot Roomba devices. It has been tested against an original iRobot Roomba i7/i8 pack, and is backed by a 12-month warranty.
What cells and configuration does the I7 use?
The I7 uses high-quality 18650 cells (2600 mAh each) arranged in a 4S1P configuration for a nominal 14.4V and a true rated capacity of 2.5Ah. Before assembly, cells are matched based on their capacity (±20 mAh) and internal resistance (±5 mΩ). You can specify your preferred cell brand (Samsung, LG, Panasonic, or BAK) when you place your order.
What is the warranty on the I7?
All I7 replacement packs come with a 12-month warranty that covers manufacturing defects. Every batch of products is shipped with the following documents:
– UN38.3 test report
– IEC 62133 certificate
– MSDS
– CE Declaration of Conformity
These documents are needed to clear customs worldwide.
How is the I7 packed for shipping?
The I7 ships 48 pieces per master carton. The battery doesn’t have any dimensions. Every batch of these products has the necessary UN38.3 / IEC 62133 / CE documents.
