PANASONIC Lithium battery BR-A 3V 1800mAh

The Ultralife UHE-ER14250-H is a compact primary lithium battery in the 1/2 AA format (half AA size). It belongs to the "High Energy" series and uses bobbin technology for maximum energy density in the smallest space. With a voltage of 3.6 V and a capacity of 1.2 Ah, it is the global standard for memory backup on computer motherboards and in industrial control systems. It offers an extremely long service life and high reliability at low discharge currents. Highlights at a glanceCompact 1/2 AA format: At just 25 mm high, it is exactly half the length of a standard AA battery, with the same diameter (14.5 mm).High energy density: Despite its small size, it delivers a capacity of 1.2 Ah, which is sufficient for years of operation in backup applications.Bobbin technology: The internal design is optimised for low self-discharge (< 2 % per year), ideal for devices that are permanently connected to the mains and only require backup in the event of a power cut.Constant 3.6V voltage: Provides a stable voltage level that is significantly higher than that of alkaline (1.5V) or lithium-manganese batteries (3.0V).Extreme temperature range: Operates reliably between -55 °C and +85 °C, making it suitable for use in outdoor sensors or heated control cabinets.Long service life: Designed for a service life of up to 10 years in low-power applications.The standard for motherboards & dive computersThe UHE-ER14250-H (often also referred to as LS14250 by Saft or SL-750 by Tadiran) is the classic "BIOS battery" for industrial computer motherboards, older Apple Macintosh models (G3/G4/G5) and PLC controls (Siemens S5/S7 backup). In addition, this format is frequently used in professional dive computers, dog collars (for tracking) and alarm system sensors used. Features ModelUltralife UHE-ER14250-H (High Energy 1/2 AA) ApplicationCMOS backup (Mac/PC), dive computers, sensors TechnologyLithium-thionyl chloride (Li-SOCl2) - Bobbin Construction Voltage3.6 V Capacity1.2 Ah (Nominal) - High energy density Max. discharge currentapprox. 40-50 mA (continuous) - Only for low loads Dimensions (L x W x H in mm)14.5 x 25.2 (size 1/2 AA) ConnectionStandard, PCB pins or solder tabs Temperature range-55°C to +85°C Special featuresExtremely long-lasting (>10 years), standard for memory backup Weight (g)approx. 10  FAQs about the Ultralife UHE-ER14250-HWhat does "1/2 AA" mean?Half length: The designation refers purely to the mechanical size. The battery has the same diameter as a standard AA battery (14.5 mm), but is only half as long (approx. 25 mm). It therefore does not fit in normal AA compartments.Can I replace it with a CR14250?Be careful with the voltage: A CR14250 (lithium-manganese) usually has 3.0 volts. The ER14250 (like this Ultralife) has 3.6 volts. In many cases (e.g. dive computers) the difference is tolerable, but some sensitive electronics absolutely require the correct voltage. Check your device manual.Is the battery rechargeable?No. This is a primary battery. Never attempt to recharge it. If you are looking for a rechargeable battery in this size, you will usually need a LiFePO4 battery (3.2V) or Li-Ion (3.7V) in size 14250, but these require a special charger.Is the battery available with solder tags?Yes. As these batteries are often permanently installed on circuit boards (e.g. in industrial control systems), they are often available with different connection types:Standard: Flat terminals for insertion into holders.Axial: One wire comes out at the top and one at the bottom (for horizontal mounting).PCB/Tags: 2 or 3 pins on the underside for direct soldering. When purchasing, pay close attention to the required connection type.

A characteristic feature is the passivation effect: a thin protective layer forms on the lithium anode, which reduces the self-discharge to an absolute minimum, enabling extremely long storage and operational capability. This ensures that energy is reliably available even after many years. Features  ModelTadiran SL-760/PR TechnologyLithium thionyl chloride (Li-SOCl₂) SizeAA (Mignon) Rated voltage (V)3.6 Capacity (mAh)2200 Max. continuous discharge current100 mA Self-dischargeapprox. 1% per year Operating temperature (°C)-55 ~ +85 Dimensions (Ø x L, mm)approx. 14.7 x 50.5 Weight (g)approx. 18 ConnectionRadial pins (PR) RechargeableNo  FAQs about this Tadiran batteryWhat does the connection with "radial pins" mean?In contrast to axial connections, which exit from the centre of the terminals, radial pins are arranged so that they exit from one face of the battery. This configuration is optimised for specific layouts on printed circuit boards (PCBs) and enables particularly stable and defined mounting of the cell.What is the advantage of the SL-700 series over other series?The SL-700 series is optimised for the absolute lowest self-discharge. It is the best choice for applications that require very little power over many years, such as memory backup in computers. In contrast, other series (such as the SL-300 iXtra) are designed for applications with higher pulse current demand.For which devices is this battery type suitable?This battery type is ideal for professional electronics in which the battery is permanently soldered and an extremely long service life is decisive. Typical applications are meters, industrial computers, alarm systems and long-life sensors with specific PCB layouts.Is this battery rechargeable?No, this is a primary lithium battery and must not be recharged under any circumstances. Attempting to charge the cell is dangerous and can lead to overheating, leakage or rupture of the cell.What does the passivation effect mean for this battery?After longer storage, a protective layer forms on the lithium surface. This layer is the reason for the extremely low self-discharge. On first use, it can lead to a short voltage delay. This should be considered in circuit design for applications that require current immediately after activation.

The cell features a hermetic glass-to-metal seal which reliably prevents electrolyte leakage. The inorganic electrolyte used is non-flammable and ensures a high degree of intrinsic safety. Each cell is designed to deliver its energy consistently and safely over a very long period, thus minimising maintenance costs and reducing the overall operating costs of your application.iXtra series: The technology for higher performanceThe iXtra series from Tadiran is designed to offer improved voltage stability under load. Compared to the standard series (SL-700), which is optimised for minimum continuous currents, the SL-300 series shows improved performance with medium load requirements and pulse currents. The passivation effect is thereby more quickly overcome, leading to a more stable power supply in applications which regularly "wake up" to perform tasks.Features  ModelTadiran SL-360/P TechnologyLithium-thionyl chloride (Li-SOCl₂) SizeAA (Mignon) Nominal voltage (V)3.6 Capacity (mAh)2400 Max. continuous discharge current130 mA Self-dischargeapprox. 1% per year Operating temperature (°C)-55 ~ +85 Dimensions (Ø x L, mm)approx. 14.7 x 50.5 Weight (g)approx. 18 ConnectionAxial wires (P) RechargeableNo  FAQs about this Tadiran batteryWhat does the "axial wire" connection mean?This model is equipped with connection wires that exit centrally from the positive and negative terminals of the cell and run in opposite directions along the longitudinal axis. This configuration allows for very flexible installation and direct, firm connection to the electronics by soldering, without the need for a battery holder.What is the difference between the SL-300 (iXtra) and the SL-700 series?The SL-300 (iXtra) series, to which this cell belongs, is optimised for applications with moderate current requirements (e.g. radio sensors). It offers more stable voltage under load. The SL-700 series, on the other hand, is designed for absolute long-term use with minimal continuous current, such as in pure memory backup applications.For which applications is this battery type suitable?This battery type is ideal for professional electronics that require a long service life, but regularly need power for functions such as data transmission. The axial wires make it perfect for installations where the cell must be firmly soldered.Is this battery rechargeable?No, this is a primary lithium battery and must under no circumstances be recharged. Attempting to charge the cell is dangerous and may result in overheating, leakage, or the cell bursting.What does the passivation effect mean for this battery?After prolonged storage, a protective layer forms on the lithium surface, which minimises self-discharge. The iXtra series is designed so that this layer is broken down more quickly and with less voltage drop under load than with the SL-700 series, which is advantageous for applications with regular current pulses.
