BPI 1.5V rechargeable lithium battery: a new choice for environmental protection and energy saving

By BetterPower June 23, 2025

With the rapid development of science and technology, all kinds of smart devices have been deeply integrated into our daily life and work. From smart wearable devices to mobile terminals, from digital photography equipment to smart home systems, they have brought us unprecedented convenience and efficiency. However, with the increasing power of equipment functions and the continuous improvement of user needs, the requirements for battery performance have also reached new heights. Traditional dry batteries have gradually exposed problems such as insufficient battery life, low energy density, unstable voltage, frequent replacement and environmental pollution, and can no longer meet contemporary needs. Against this background, BPI 1.5V rechargeable lithium battery came into being. With its excellent performance and innovative technology, it provides a new power solution for smart devices and opens a new energy era.

Ⅰ、Core advantages of BPI 1.5V rechargeable lithium battery

  • Stable voltage, reliable performance

BPI 1.5V rechargeable lithium battery adopts advanced voltage stabilization technology, and the output voltage is stable at 1.5V throughout the process. Whether it is accurate blood pressure measurement by electronic blood pressure monitor or remote control by remote control, it can ensure that the equipment is always in the best condition.

  • Super energy, strong power


BPI 1.5V rechargeable lithium battery has high energy density, the maximum energy of No. 5 battery is 3600mWh, and the maximum energy of No. 7 battery is 1100mWh. Once charged, the usage time is much longer than ordinary batteries, equivalent to 3 traditional dry batteries.

  • Fast charging, efficient and convenient


BPI 1.5V rechargeable lithium battery supports fast charging function. Some products are integrated with USB (TYPE-C) port, which can be easily charged using mobile phone/computer charger or power bank, and can be charged anytime, anywhere, which is efficient and convenient.

  • Extremely long life, economical and environmentally friendly


There is almost no self-discharge phenomenon inside, and it can be recharged repeatedly for more than 1,000 times. Long-term use saves expenses, reduces battery waste, and conforms to the concept of environmental protection.

  • Convenient and universal, ready to use


The appearance and size are consistent with common alkaline dry batteries, with complete specifications such as No. 5, No. 7, C, D, 9V, etc., suitable for various battery-required equipment, no need for modification, buy and replace.

Ⅱ、Core advantages of BPI 1.5V rechargeable lithium battery

BPI 1.5V rechargeable lithium battery can completely replace traditional dry batteries due to its excellent performance and is widely used in many fields.

  • Consumer electronics


Smart home accessories such as smart door locks and wireless doorbells can last for 6 to 12 months with BPI batteries. Medical and health equipment such as electronic blood pressure monitors and blood glucose meters, whose voltage stabilization characteristics ensure accurate measurement data. TV/air conditioner remote controls, electric toothbrushes, wireless mice, etc., have a battery life increase of 3 to 5 times.

  • Internet of Things and sensor network


Low-power sensors such as agricultural greenhouse temperature and humidity sensors and cold chain logistics temperature recorders, with a single battery supporting 1 to 2 years of battery life. Some lightweight smart home gateways can be operated off-grid with solar panels.

  • Industrial and medical equipment


Industrial handheld tools such as laser rangefinders and digital multimeters have high current output characteristics to meet high-load operation requirements. Portable medical portable equipment such as portable electrocardiographs and emergency defibrillators work stably in an environment of -20℃~50℃.

  • Consumer electronics and toys


The power output of electric remote control cars and smart robot toys is increased by 40%. Outdoor electronic devices such as flashlights and fishing alarms support IP67 waterproof design and can work stably in rainy or humid environments.

  • New energy and energy storage supplement field


Micro energy storage systems such as solar garden lights and camping portable power supplies can convert solar energy into stable electricity with MPPT controllers. Backup power supply scenarios such as home emergency power supply and smart meter clock modules use low self-discharge characteristics to ensure that data is not lost during power outages.
