Performance and Cycle Life Advantages
Memory Effect and Discharge Characteristics
Unlike older NiCd cells, this NiMH design exhibits minimal memory effect, allowing partial discharges without significant capacity loss.
Discharge curves remain relatively flat, supporting steady current draw for devices such as portable meters and handheld scanners.
Practical Applications in Field and Clinical Settings
Use in Portable and Battery-Constrained Platforms
Engineers favor this model for end-of-line testers, small instrumentation, and compact battery packs where reliability is non-negotiable.
Its stable voltage under load and low self-discharge make it suitable for temporary installations where frequent battery swaps are impractical.
Key Takeaways for Engineers and Procurement Teams
- Reliable 800 mAh capacity in a compact microbattery form factor
- NiMH chemistry reduces memory effect compared to older NiCd designs
- Ideal for medical devices, IoT nodes, and portable test equipment
- Requires appropriate charger with NiMH safety cutoffs

FAQ
Reader questions
Is this battery a direct replacement for older alkaline versions in microbattery housings?
It can replace disposable cells in compatible holders, but you must verify charging circuitry is present, as NiMH requires a different charge profile.
How should I store the Varta 55615702012 if it will sit unused for months?
Store it at partial charge around 40–60% in a cool, dry environment to minimize self-discharge and preserve cell longevity.
Can I use a standard NiMH charger without risk of overcharge?
Ensure your charger supports NiMH chemistry and includes automatic cutoffs or trickle-charge management to prevent overcharging.
What safety precautions are necessary when handling this microbattery?
Avoid short-circuiting the terminals, do not physically deform the cell, and keep it away from sources of heat or open flame during use and storage.
