Varta NiMH rechargeable battery 3.6V 150mAh memory series with soldering pins

This high-quality VARTA NiMH battery pack is designed as a reliable backup power source for data preservation in professional electronic assemblies. With a nominal voltage of 3.6 V and a capacity of 150 mAh, it ensures the preservation of memory data (memory backup) and real-time clocks (RTC) in case of failure of the primary power supply. The specific arrangement of the solder pins (+ 2-pin / - 1-pin) allows secure and reverse polarity safe mounting directly onto the PCB.

Highlights at a glance

• Maximum data security: Designed for memory backup use to protect volatile memory (SRAM) and real-time clocks (RTC).
• Reliable NiMH technology: Proven and robust nickel-metal hydride technology for a long service life.
• Industrial quality: High cycle durability and a wide operating temperature range for demanding environments.
• Safe PCB mounting: Asymmetric solder pins (+ 2 pins, - 1 pin) for reverse polarity-safe and solid installation.
• Can be charged continuously: Ideally designed for standby operation with constant trickle charge in the device.

Reliable backup power for industry

This VARTA battery pack is the first choice for securing critical data in a variety of industrial and professional applications. It is typically used in programmable logic controllers (PLC), industrial PCs, measuring and metering systems (electricity, water, gas), medical technology and in telecommunications and security technology. Wherever the loss of configurations, log data or time stamps must be prevented, this battery provides the necessary security.

Robust and proven NiMH technology

Nickel-metal hydride technology (NiMH) offers decisive advantages over older NiCd batteries. It is characterised by high energy density, very low memory effect and better environmental compatibility. The VARTA storage series batteries are specially designed for long-term operation and tolerate the continuous trickle charge typical of backup applications for many years.

Efficiency and safety by design

VARTA batteries for industrial applications are subject to the strictest quality controls to ensure consistently high performance and maximum operational safety. The battery pack design and the quality of the individual cells ensure reliable operation even under demanding thermal conditions. Direct soldering onto the board ensures a permanently safe and vibration-resistant electrical connection.

FAQs about the VARTA NiMH backup battery

What does the pin arrangement "+ 2-pin / - 1-pin" mean?

This asymmetric arrangement of the solder pins provides mechanical reverse polarity protection. It ensures that when mounting on the PCB the battery pack cannot be accidentally soldered with incorrect polarity. This protects the electronics of the module and the battery itself from damage.

Can this NiMH battery replace an old NiCd battery?

In many cases, replacement is possible if voltage (3.6 V), capacity and the physical dimensions including pin layout match. However, it must be ensured that the device's charging circuit is compatible with NiMH batteries. For most modern trickle charge applications, this is the case.

How is this battery charged?

This battery pack is intended for permanent installation in a device and is supplied by its internal charging circuit. It is not intended for charging in external standard chargers. The main device's electronics supply the battery with a low trickle charge during normal operation to keep it fully charged at all times.

How should this battery be disposed of?

Batteries must not be disposed of with household waste. As an industrial battery, it is subject to the provisions of the Battery Act. Please take the used battery to the designated industrial or municipal collection points to ensure proper and environmentally friendly disposal.
