The Ultralife U9VLJP-BP (technically U9VL-J-P) is the world's best-known and most widely used 9V lithium battery for long-term applications. It is the modern successor to the classic alkaline 9V blocks and outperforms them in every respect: it lasts up to 5 times longerThe Ultralife lithium round cell is lighter and works reliably even at extreme temperatures. It is particularly well known as a "10-year battery" for high-quality smoke detectors, as it often does not need to be replaced for the entire service life of the detector. It is supplied in practical individual blister packs (BP = Blister Pack).Highlights at a glance10 years safety: Enables a service life of up to 10 years in many ion smoke detectors, making the annoying nightly "beeping" due to low batteries a thing of the past.Highest capacity (1200mAh): With 1200 mAh, offers almost twice the capacity of a high-quality alkaline battery (approx. 500-600 mAh) and four times that of a zinc-carbon battery.Flat discharge curve: Keeps the operating voltage constantly high for a long time. While alkaline batteries lose voltage linearly, the Ultralife delivers full power until shortly before the end.Ultralight: Weighs approx. 37 g, around 25 % less than a conventional 9V block (approx. 45-50 g), making it ideal for portable devices such as wireless microphones or medical monitors.Extreme temperature range: Can be used from -20 °C to +60 °C - perfect for applications in cold garages, storage rooms or outdoors (e.g. electronic door locks).Long shelf life: Thanks to lithium technology, it has an extremely low self-discharge rate and can easily be stored for 10 years before being used.The standard for smoke detectors & medical technologyThe Ultralife U9VLJP is the Original equipment battery for almost all major manufacturers of high-quality smoke alarms. It is also extremely popular in the Medical technology (infusion pumps, patient monitors), in the Safety technology (alarm systems, motion detectors), for Musicians (active pickups for guitars, radio links) and in industry for data loggers. Features ModelUltralife U9VL-J-P (U9VLJP-BP blister) ApplicationSmoke detector (10-year use), medical, audio, security TechnologyLithium manganese dioxide (Li-MnO2) primary cell Voltage9 V (nominal) - Voltage stable Capacity1200 mAh (twice as much as alkaline) Shelf life10 years (low self-discharge) Dimensions (L x W x H in mm)48.5 x 26.5 x 17.5 (standard 9V block / E-block / 6LR61) ConnectionSnap connection (miniature push button) Temperature range-20°C to +60°C (can also be used in cold conditions) Special featuresThe "10-year battery", very light, no leakage Weight (g)approx. 37 (Significantly lighter than alkaline ~45g) FAQs for Ultralife U9VLJP-BPIs this battery rechargeable?No! This is the most common mistake. It is a Lithium primary battery (disposable). Never attempt to charge this battery in a charger (risk of explosion). If you are looking for rechargeable 9V batteries, you need "NiMH" or "Li-Ion batteries" (often 8.4V or 7.4V).Does it fit mechanically in every device?Yes, the U9VLJP corresponds to the standard size ANSI 1604. In very rare cases with very old devices, the battery compartment can be extremely tightly tolerated, as alkaline batteries have rounded corners, while the Ultralife is somewhat more "angular" (see picture). However, it fits perfectly in 99.9 % of modern devices (smoke detectors, multimeters, toys).Why is it so much more expensive than an alkaline battery?The higher price is offset by the service life. A Ultralife lasts up to 5 times longer than a standard battery.Calculation example: If you change an alkaline battery (approx. €2) in a smoke detector every 1-2 years and have to fetch a ladder each time, this costs approx. €10-20 plus labour over 10 years. A Ultralife (approx. €8-10) often lasts the full 10 years. You save money and effort.How do I dispose of the battery?As this is a lithium battery, please cover both poles with a strip of adhesive tape before disposal (risk of short circuit in the collection container). Then hand them in at an official battery collection point (supermarket or recycling centre).
