NEW DELHI: HP rates the HP 400 Quiet Wireless Mouse for up to 24 months from one AA battery, but describes that duration as an estimate affected by usage and operating conditions. The Pink model, AZ7B5AA#UUF, is listed at Rs 1,829 including taxes in India. Its battery figure should be read alongside its connection options and separate one-year limited warranty.

Price as of 8 November 2026, 00:15 IST. The price refers to the Pink product code above. HP's broader material describes multiple colours, but this report does not assign a price to another finish. The India product page and the corresponding Pink-model datasheet were the sources used for the specifications.
What the 24-month statement actually covers
The battery footnote names active, idle and sleeping hours among the factors that affect life. It also mentions the number of applications running, environmental conditions and the features being used. HP says results vary and battery capacity decreases with age and use. Those qualifications rule out treating the headline duration as a fixed replacement date for every owner.
For a person who uses the same mouse at a home desk, in classes and while travelling, the meaningful question is how the accessory is used over time. A lightly used household computer and a desk occupied throughout the day need not produce identical results. This is a manufacturer estimate, rather than a battery test conducted by this publication.
The distinction matters when a mouse becomes unreliable sooner than expected. The elapsed time since purchase alone does not identify the cause. Keep a record of the connection in use and the symptom you actually see, such as an interrupted connection or inconsistent pointer movement. That is more useful information than assuming every problem must reflect an inaccurate battery claim.
One AA cell, two connection routes
HP lists a USB dongle and one AA battery in the box. The mouse can use Bluetooth or its 2.4GHz wireless connection, giving owners separate ways to connect to compatible equipment. A computer with a USB Type-A port can accommodate the supplied receiver, while a Bluetooth setup depends on Bluetooth support at the host device.
These connection options are relevant to the real layout of a desk. A laptop may have its ports occupied by storage or another peripheral, whereas a desktop may have a convenient receiver location. Decide the connection arrangement before judging the convenience of the mouse. This report does not claim that one connection mode delivers a longer battery life than the other.
The official wireless range is up to 10 metres in an open area. That qualifier deserves to stay attached to the figure. An open-area specification is not a promise of the same behaviour through every wall, desk or room layout. It also says nothing by itself about the accuracy of pointing on the surface beneath the mouse.
Surface tracking has its own limit
The Pink datasheet advertises adjustable sensitivity up to 6,000 dpi and lists a nominal sensor value of 1,200 dpi. These are sensitivity specifications, not measurements of click speed or the time taken to complete a task. A larger maximum number should not be turned into a claim of better accuracy for every user.
HP calls the sensor suitable for multiple surfaces, while its footnote says glass can affect functionality. That is particularly relevant to a glass-topped work table: the battery estimate and sensor claim are separate issues. If pointer behaviour is inconsistent on that table, the surface qualification remains relevant even when the battery has plenty of life left.
The other distinctive feature is the liquid silicone rubber exterior. HP describes it as soft and easy to clean and sanitise, and presents the design as suitable for either hand. The published dimensions provide a useful reference for physical fit, but the shape still needs to suit the individual. We have not assessed comfort or measured click noise.
The warranty uses a different clock
The India listing and Pink datasheet specify a standard one-year limited warranty. That is separate from the up-to-24-month battery estimate. Neither statement should be substituted for the other. For an actual product fault, retain the warranty card and invoice and use the terms supplied with the product to identify what is covered.
For other peripheral coverage, read our HP 430 Multi-Device Wireless Mouse price: Rs 2,229, HP OMEN 24 price list: Rs 14,000 to Rs 18,290 and HP Smart Tank 580 vs 585 price: 585 starts lower at Rs 14,999. Their connection and pricing details concern separate models and should not be used to extend this mouse's battery or warranty claims.
