Energizer E96 AAAA Batteries

Energizer E96 AAAA Batteries

Energizer E96 is a primary (non-rechargeable) AAAA alkaline battery designed for ultra-slim devices that require reliable 1.5V power in a narrow, lightweight form factor. Typical applications include active stylus pens, clinical penlights, laser pointers, glucose meters, and compact diagnostic tools.

Cross-Reference

• Size names: AAAA, E96 (Energizer), LR61 (IEC), MN2500 (cross-reference)
• Chemistry: Alkaline (primary)

Key Specs

Parameter	Typical Value
Nominal voltage	1.5 V
Form factor	AAAA (E96 / LR61)
Diameter	≈ 8.3 mm
Length	≈ 42.5 mm
Use profile	Low to moderate drain; intermittent bursts
Shelf life	Multiple years when stored cool and dry

When to Choose E96 AAAA

• Use if your device explicitly specifies AAAA/E96/LR61.
• Best for slim housings where AAA will not fit (stylus pens, mini flashlights, compact meters).
• Avoid using adapters or spacers to fit other sizes—this can cause poor contact, device errors, or damage.

Estimated Runtime (Typical Use)

• Stylus pens: weeks to months of normal note-taking/drawing (varies by polling rate and features).
• Penlights: roughly 2–8 hours of cumulative on-time, depending on LED brightness and duty cycle.
• Laser pointers: several hours of intermittent use. Dim output indicates it’s time to replace.

Note: Actual runtime depends on device load, ambient temperature, and usage patterns.

Packs and Buying Advice

• Individuals (stylus, penlight): 2–4 pack—keep one sealed spare.
• Small teams/classrooms: sleeves of 10–25 to reduce trips and shipping.
• Departments/OEMs: inner or master cases for predictable replenishment and lower unit cost.

Compatibility & Fit

• AAAA and AAA are not interchangeable—AAAA is smaller in length and diameter.
• Match markings on the device or old cell: AAAA, E96, or LR61.
• Avoid DIY spacers or taped stacks; they can cause intermittent power and calibration drift.

Installation

1. Confirm size: AAAA/E96/LR61 on the device or manual.
2. Align polarity: match (+) and (–) to the diagram; small bays make reversal easy.
3. Clean contacts: wipe gently with a dry, lint-free swab if contacts look dull.
4. Seat fully: close caps or battery doors snugly to ensure contact pressure.
5. Stylus check: re-pair if required and test line/pressure response.

Care, Storage & Cost Tips

• Store cool and dry; avoid glovebox heat and damp areas.
• Keep cells in original packaging until use to prevent shorting.
• Label install month/year on mission-critical tools to replace proactively.
• Estimate usage (e.g., 1–2 cells per stylus per year) to right-size orders.

Troubleshooting

• No power: recheck polarity, reseat cap, and inspect springs/contacts.
• Erratic stylus: clean contacts, reseat battery, and re-pair with the host device.
• Dim penlight or weak laser: install a fresh E96; inspect lens/LED head for residue.

Safety & Disposal

• Do not recharge—E96 is a primary alkaline cell.
• Keep away from children and pets; ingestion hazard. Seek immediate medical attention if swallowed.
• Do not mix new and used cells in multi-battery devices.
• Recycle where available; many retailers and communities accept alkaline batteries.

FAQ

Is Energizer E96 the same as AAAA?

Yes. E96 is Energizer’s designation for the AAAA alkaline cell. You may also see LR61 or MN2500 as cross-references.

Will AAAA fit where AAA is specified?

No. AAAA is smaller and will not substitute for AAA. Use only the size listed by your device.

How long do AAAA batteries last in a stylus?

Typically weeks to months, depending on usage intensity, Bluetooth features, and polling rate. Replace when strokes are missed or pressure sensitivity degrades.

Are bulk and retail versions different?

The cells perform the same; packaging differs (carded retail vs. sleeves/cases for stocking).

Can I recharge or “revive” an E96 AAAA?

No. Do not attempt to recharge primary alkaline cells. Replace with a fresh battery.
