## Product: Energizer Ultimate Lithium AA Batteries (24 Pack)
**Brand:** Energizer

## Pros
- Batteries perform exceptionally well in high-drain devices like beard trimmers, lasting three to four months per set.
- Functionality tests on received batteries showed they were working despite expiration date concerns.
- Packaged in original retail packs, which some users prefer over bulk packaging.
- Imported from Singapore with consistent model and packaging, maintaining brand authenticity.

## Cons
- Many users report batteries arriving not fully charged, making them unreliable right out of the package.
- Expiration dates on batteries are consistently earlier than advertised (March 2024 vs. expected 2025 or later), raising concerns about old or expired stock.
- Significant reports of early battery failures, with some devices like security cameras experiencing malfunctions due to dead batteries within weeks.
- Performance in wireless mice is underwhelming; lithium batteries here do not last significantly longer than cheaper alkaline alternatives.
- Overpriced for the actual battery life and performance delivered, especially compared to regular alkaline or other premium brands.
- Packaging inconsistencies and fulfillment errors led to receiving fewer batteries or mixed pack sizes.
- Customer service has often been ineffective or unhelpful regarding product or fulfillment issues.
- Regular Duracell alkaline batteries sometimes outperform these lithium batteries in durability for low-drain devices.

## Bottom Line

If you’re powering high-drain devices like beard trimmers, these Energizer Ultimate Lithium AA batteries deliver solid, long-lasting performance. However, for everyday low-drain gadgets like wireless mice, their extra cost doesn’t translate into noticeably longer life, and users frequently face inconsistent charging and early failures. The suspiciously early expiration dates and reliability issues especially in sensitive electronics like security cameras are red flags. For better peace of mind and value, you might want to explore more consistent battery options or stick with top-tier alkaline batteries for less demanding uses.
