A: Yes. We can provide CR123A replacement for Panasonic, featuring the same performance.
A: Yes. We have the limno2 battery MSDS for different models. You can send mail to info@vtcbatt.com.
A: For LiMnO₂ battery disposal, you can’t drop the batteries into the regular household bins directly,which will cause a short circuit and fire.
First, you need to fully discharge the batteries to 0V to avoid the risk of a short circuit.
Some people even suggest salt immersion, which is actually proven to be invalid.
Even if you want to store them, you need to keep batteries in a plastic bag or box instead of pockets or metal containers.
Second, you need to avoid any exposure to a leaked LiMnO₂ battery, especially sulfuric acid on skin and eyes, which will not only cause burns and irritation of the respiratory system, but also bad feelings of redness, tearing, and burns.
Third, you need to find a manganese dioxide battery disposal near you, while most supply stores, such as Best Buy, Home Depot, and Walmart, provide battery recycling trash.
Following the local battery disposal regulations to find “battery disposal near me” is the best way to dispose of the batteries. Otherwise, you have to find a hazardous waste company to dispose which are under a cost.
A: Normally, the lithium-manganese dioxide (Li-MnO₂) batteries are not rechargeable, which is a primary lithium battery with the danger of being recharged. We only have ML2032 and ML1220 two rechargeable LiMnO₂ batteries.
Yes. We can assemble four cells of 3.0V LiMnO₂ cells to 12V packs, satisfying the 12V output voltage demand of different devices.
A: Thanks to the low self-discharge rate of 1% per month, the LiMnO₂ batteries can power a low-consumption device for 10 years. But the power consumption is higher, then the shelf life will be shorter.
Yes. We have plenty of stock of this CR2035 battery, and you can also get it directly from our worldwide dealers.

Military Electronics
An Australian defense integrator uses our high-pulse-rate spiral Li-MnO2 cells for tactical telemetry nodes that experience extreme thermal shifts. The hardware requires zero-passivation power over a -40°C to +125°C temperature range. Laser-welded glass-to-metal seals prevent leakage during supersonic expansion, holding a stable 2.4V rail under sudden >1.5A bursts.
Yes. Li-MnO2 battery is classified as a lithium metal battery. It utilizes a solid lithium metal anode paired with a manganese dioxide cathode. Because it uses pure metallic lithium rather than lithium ions intercalated in graphite, it is strictly categorized as a primary (non-rechargeable) lithium metal cell under international transport and safety regulations (UN3090).
A CR battery is an IEC-designated primary (non-rechargeable) lithium manganese dioxide Li-MnO2 cell. In the ‘CR’ prefix, ‘C’ defines the lithium metal anode/manganese dioxide cathode chemistry, while ‘R’ denotes a round or cylindrical form factor. Operating at a 3.0V nominal rail, these cells are the global industry standard for low-power IoT assets, RTC backups, and automotive TPMS nodes due to their zero-passivation characteristics and 10-year shelf life.
Both CR2032 and CR2450 share the identical 3.0V Lithium Manganese Dioxide Li-MnO2 chemistry and IEC classification; their practical divergence comes down to physical envelope volume, energy capacity, and load discharge boundaries:
CR2032 vs CR2450 Engineering Table
| Technical Parameter | CR2032 | CR2450 | Engineering Impact / Application Delta |
| IEC Chemistry | Li-MnO2 (Lithium Metal) | Li-MnO2 (Lithium Metal) | Identical 3.0V nominal OCV and 2.0V cut-off discharge plateau behavior. |
| Diameter | 20.0 mm | 24.5 mm | CR2450 requires a larger radial PCB landing zone layout. |
| Height | 3.2 mm | 5.0 mm | CR2450 is 1.8mm thicker, impacting ultra-low-profile hardware enclosures. |
| Nominal Capacity | 220 – 240 mAh | 600 – 620 mAh | CR2450 delivers ~2.7x higher energy density for extended field reliability. |
| Cell Weight | ~3.0 g | ~6.2 g | Mass footprint doubles. Critical constraint for weight-sensitive medical wearables. |
| Max Continuous Current | 3.0 mA | 6.0 mA | CR2450 handles higher base steady-state loads without internal resistance spikes. |
| Max Pulse Capability | 15.0 mA | 30.0 mA | CR2450 minimizes voltage dips during high-current wireless transmission bursts. |
| Target Applications | RTC Backup, Key fobs, Active Tracking Tags | Electronic Shelf Labels (ESL), Patient Monitors, Smart Valves | Selection Guide: Choose CR2450 if the enclosure tolerates thickness and the project demands 5+ year runtime. |
Yes. Li-MnO2 cells can explode under severe electrical or thermal abuse. They utilize a pure lithium metal anode paired with a flammable organic electrolyte. External short circuits or forced over-discharge trigger violent thermal runaway. Exceeding the separator’s melting point causes the same catastrophic breakdown. Rapid gas propagation drives internal pressure buildup. Industrial packs must deploy hardware-level safety boundaries. Integrated PCMs and thermal fuses isolate these electrical faults. Precision structural venting safely handles unexpected casing expansion.
Li-MnO2 batteries have a 10-year shelf life under controlled storage. The chemistry maintains an annual self-discharge rate below 1% at room temperature. Ambient storage between +10°C and +25 °C optimizes long-term capacity retention. Temperatures exceeding +60 °C accelerate electrolyte decomposition and cause permanent degradation. Unlike Li-SOCl2 cells, Li-MnO2 does not develop a restrictive passivation layer. The cells deliver instantaneous pulse currents immediately after multi-year storage without voltage delay.
Yes, but only certain LiMnO2 battery models can operate below -40°C. The low temperature performance depends strictly on cell design. Standard Li-MnO2 cells suffer severe electrolyte crystallization and a capacity drop below -40°C. To handle these deep-freeze environments, we engineer specialized low-viscosity organic electrolyte formulations and high-pulse spiral architectures. These specific configurations maintain low internal resistance below -40°C.The battery can deliver steady burst currents without voltage rail collapse. Review your model numbers with our engineering team to verify compatibility with extreme-low-temperature conditions.
Yes, but only certain LiMnO2 battery models can operate above 100 °C. Standard Li-MnO2 cells are prone to separator degradation and thermal runaway above 60°C. Not all models support high-temperature operation. For environments up to 125°C, we manufacture specialized cells utilizing hermetic glass-to-metal seals (GTMS) and modified electrolytes. These engineering controls prevent gas evolution and casing expansion. You must verify the operational thermal profiles with our team to determine the correct high-temperature part number.
Yes. We customize primary Li-MnO2 packs directly at our production facilities. Our team configures standard cells to match your hardware layout. We build custom multi-cell series or parallel assemblies in different voltages and capacities. Factory-welded JST, Molex, or Hirose connectors eliminate manual assembly soldering. We integrate dedicated hardware PCMs to safely handle wide-dynamic-range pulse loads. Send your mechanical boundaries and load duty cycles to lock down a production-ready specification.

You can swap cells without altering PCB layouts or enclosure plastics. Email your current competitor part numbers to get the cross-reference datasheets.
Do not recharge primary Li-MnO2 batteries. Forcing current into a lithium metal anode causes internal dendrite growth. These crystalline structures pierce the separator, triggering a direct short circuit. The resulting exothermic reaction leads immediately to thermal runaway. Rapid electrolyte vaporization drives severe pressure buildup, causing casing rupture, fire, or explosion. To prevent accidental charging from power rails, your circuit layout must integrate blocking diodes or hardware isolation.
Different electronic devices require different battery connection structures.VTCBATT provides customized LiMnO₂ battery terminal solutions, including tab position, tab length, solder pin terminals, and connection structures.Our engineering team can optimize the battery terminal design according to the customer’s PCB layout, installation space, and electrical requirements.

For electronic devices powered by LiMnO₂ coin cells or cylindrical cells, engineers should prevent reverse current caused by external power sources.
When incorporating a lithium primary battery into a circuit powered by an independent main power source, protective devices shall be used in order to prevent charging the primary battery from the main power source, for example:
a)a blocking diode and a current limiting resistor (see Figure a);
b)two series blocking diodes (see Figure b);
c)circuits with a similar blocking function based on two or more independent protective devices: provided the first protective device is capable of limiting the charging current through the lithium battery to the normal reverse current specified by the manufacturer, which can be applied to the battery during its operating life, while the second protective device is capable of limiting the charging current to the abnormal charging current specified by the battery manufacturer. The circuit shall be so designed that at least one of these protective devices remains operational when any one component of the circuit fails.

How reliable is a LiMnO₂ battery after long-term storage?
-Reliability Comparison
According to Van’t Hoff’s law, for every 10°C rise in temperature, the rate of chemical reaction increases by a factor of 2 to 4. According to this kinetic law of chemical reaction and battery production practice, it is generally believed that battery storage at 60 °C for 20 days is equivalent to 1 year at room temperature.In the actual production process, we also usually use this method to test and evaluate the service life of the product
