Keep original packaging until use to prevent accidental discharge. Industrial users should implement barcode tracking and FIFO rotation systems to ensure proper stock rotation.
Can I mix GP lithium AAA with other battery types in the same device?
Never mix chemistries – this creates dangerous imbalances. Even mixing old/new GP lithium cells is problematic. In multi-battery devices:
1) use same production lot batteries,
2) verify voltage within 0.03V difference, and
3) replace all cells simultaneously.
For critical medical equipment, consider GP’s pre-matched battery packs with guaranteed performance parity.
Why does my device show “low battery” warnings with GP lithium AAA when they still work?
Many devices use voltage-based alerts calibrated for alkaline’s steep discharge curve. GP lithium maintains higher voltage longer, triggering false warnings. Solutions:
1) Update device firmware if available,
2) Use battery adapters with voltage regulators, or
3) For smart devices, recalibrate power management settings to recognize lithium characteristics.
