FAQs
Can I replace a standard coin cell with this battery?
No, this is a NiMH rechargeable battery. It requires a compatible charging circuit and has different dimensions and pin configurations compared to standard non-rechargeable lithium coin cells.
What is the weight of the Varta V 150 H?
The battery weighs 16g.
Is this battery suitable for high-drain applications?
No, this series is designed specifically for low-drain memory backup and timing applications, not for devices requiring high current bursts.
What should I do if the pins do not align with my board?
You should not attempt to force or bend the pins excessively. Ensure the battery model matches your specific PCB footprint requirement before purchase.
Does this battery require a specific charger?
It is intended to be used with the integrated charging circuitry already present in the device it is powering (such as a motherboard or controller).
Troubleshooting
Battery fails to maintain memory after power-off
Check the soldering joints on the PCB pins for cold solder points or breaks.
Battery voltage is below 2.4V
Verify if the charging circuit on the host device is functioning; the battery may be deeply discharged from a long period of inactivity.
Pros and Cons
Pros
- Excellent overcharge resistance
- High energy density for small devices
- Reliable operation in varying temperatures
- Purpose-built for memory backup applications
Cons
- Requires soldering for installation
- Not intended for high-drain motor applications
- Fixed terminal configuration may not suit all PCB layouts
Setup, Compatibility & Care
To install this battery, ensure your PCB design matches the 2.4V requirement and has the corresponding through-holes for the pins. Because this is a nickel metal hydride (NiMH) battery, it is essential to follow correct charging protocols. Avoid exposure to extreme heat, as this can reduce the battery cycle life. When soldering the PCB pins, use a low-wattage iron and keep exposure time to a minimum to prevent thermal damage to the internal cell components. Periodically check the mounting points for signs of oxidation if the device is kept in a high-humidity environment.
