Real-World Example: Matching Batteries to Device Requirements
A trail camera requiring 1.5V at 800mA pulses needs the L92BP-4 datasheet’s “Intermittent Discharge” section to confirm pulse capability. Without this data, you might mistakenly choose alkaline batteries that voltage sag under high current, causing missed wildlife photos.
Pro Tip: Bookmark Energizer’s Battery University portal for complementary guides on interpreting discharge curves and optimizing battery selection for your specific device type.
How to Interpret Key Specifications in the Energizer AAA Lithium Datasheet
Understanding the technical details in your Energizer AAA lithium battery datasheet is crucial for optimizing device performance. These specifications aren’t just numbers – they reveal how the battery will behave in real-world conditions.
Decoding the Discharge Curve
The voltage discharge graph is perhaps the most valuable yet misunderstood section. Unlike alkaline batteries that show steady voltage decline, Energizer lithium batteries maintain a flat discharge profile until nearly depleted. For example:
- At 100mA load: Voltage stays above 1.4V for 90% of the discharge cycle
- At 500mA pulse loads (common in digital cameras): Voltage dips to 1.35V but recovers quickly
This explains why lithium batteries outperform alkalines in high-drain devices – they deliver consistent power rather than fading gradually.
Temperature Performance Explained
The datasheet’s temperature range section (-40°C to 60°C) doesn’t tell the whole story. In reality:
- Below -20°C: Capacity reduces by 15-20%, but the battery still functions
- Above 45°C: Self-discharge increases slightly (about 0.5% per month)
For arctic expeditions, this means packing 20% extra batteries. For desert use, you’ll want to store spares in insulated containers.
Capacity vs. Load Current
The rated 1250mAh capacity assumes a 100mA continuous drain. However:
- At 25mA (smoke detector): Actual capacity increases to ~1400mAh
- At 1000mA (high-power flashlight): Capacity drops to ~1100mAh
This nonlinear relationship explains why battery life varies dramatically between devices. Always cross-reference your device’s current draw with the datasheet’s “Capacity vs. Discharge Rate” table.
Professional Tip: Calculating Real-World Runtime
To estimate actual battery life:
1. Measure your device’s average current draw (use a multimeter)
2. Find the corresponding capacity in the datasheet
3. Divide capacity (mAh) by current (mA)
4. Apply a 15% safety margin for aging effects
For a GPS drawing 150mA, the calculation would be: (1200mAh / 150mA) × 0.85 = 6.8 hours

Frequently Asked Questions About Energizer AAA Lithium Batteries
What makes Energizer AAA lithium batteries different from regular alkaline batteries?
Energizer lithium batteries use lithium iron disulfide (Li-FeS₂) chemistry, providing 3x the energy density of alkaline batteries (300Wh/kg vs 100Wh/kg).
They maintain stable voltage (1.5V) even under high-drain conditions, unlike alkalines that gradually decline. Their operating range (-40°C to 60°C) far exceeds alkaline’s -20°C to 54°C limit. The lithium construction also makes them 33% lighter – critical for portable devices.
How do I verify if my Energizer lithium batteries are genuine?
Authentic Energizer lithium batteries have:
1) A holographic security label that changes color when tilted,
2) Precise laser-etched batch codes (not printed),
3) Matte finish wrappers with crisp branding, and
4) Patent numbers (like US8,999,563) on the label.
Counterfeits often fail the “drop test” – genuine lithium batteries bounce less than alkalines due to denser internal construction.
Can I recharge Energizer Ultimate Lithium AAA batteries?
No, these are primary (non-rechargeable) cells. Attempting to recharge them can cause dangerous thermal runaway, as the lithium chemistry isn’t designed for reverse current flow.
For rechargeable options, consider Energizer’s NiMH offerings instead. The datasheet explicitly warns against charging with a bold “DO NOT RECHARGE” notice in the safety section.
Why does my device show low battery warning with lithium batteries that still test good?
Many devices use simple voltage checks calibrated for alkaline discharge curves. Since lithium maintains higher voltage until depletion, this triggers false warnings. Solutions:
1) Ignore warnings and track actual runtime,
2) Use devices with lithium-compatible firmware, or
3) For critical applications, implement external coulomb counting (measuring actual mAh consumed).
What’s the proper way to store unused lithium batteries long-term?
Optimal storage requires:
1) Original packaging or non-conductive cases, 2) 10-25°C temperature with <50% humidity,
3) Away from metal objects, and
4) Periodic voltage checks every 6 months.
For >5 year storage, vacuum-seal with desiccant packs. Never refrigerate – condensation risks terminal corrosion despite lithium’s wide temperature tolerance.
How do I safely dispose of depleted lithium AAA batteries?
Follow this protocol:
1) Tape both terminals with non-conductive tape,
2) Place in rigid plastic container (never metal),
3) Take to certified recycling centers (Call2Recycle.org locations), and
4) Never mix with alkaline recycling streams.
Some municipalities require separate hazardous waste handling – check local regulations as fines for improper disposal can exceed $500 per incident.
Can I use lithium AAA batteries in all my devices that take standard AAA?
While compatible in size, avoid lithium batteries in:
1) Cheap toys with no voltage regulation,
2) Smoke alarms with “alkaline-only” warnings, and
3) Devices drawing <5mA continuously (lithium’s self-discharge may outpace usage).
Ideal applications include digital cameras (high drain), GPS units (wide temp range), and medical devices (reliable voltage).
Why are my lithium batteries draining faster than expected in cold weather?
Below -20°C, lithium capacity temporarily reduces by 15-20% due to slowed ionic movement. Mitigation strategies:
1) Keep spares in inner pockets (body warmth),
2) Use hand warmers in battery compartments,
3) Select devices with battery insulation, and
4) Pre-warm batteries before use.
Capacity fully recovers when temperatures normalize – this isn’t permanent damage.
