Energizer E95 Max (D)

Energizer E95 Max D (LR20) Alkaline Battery

The E95 Max is a single-use 1.5 V alkaline D-cell built for devices that need steady, high-capacity power—think camping lanterns, large flashlights, portable radios, and emergency equipment. It uses Energizer’s leak-resistant PowerSeal technology and is rated for up to 10 years in storage, making it a strong pick for both everyday use and preparedness kits.

Best for

• Large LED flashlights and searchlights
• Camping and emergency lanterns
• Portable stereos/radios and heavy-duty toys
• Tools and equipment that specify alkaline D cells

Use it if / Avoid it if

• Use if: You need reliable power with long storage life, you use the device occasionally, or you want simple, maintenance-free batteries.
• Avoid if: You use the device daily or for very long sessions (consider rechargeable NiMH D cells), or you need strong cold-weather performance (primary lithium D cells—where available—or devices that use lithium AA may perform better below freezing).

Runtime planning (simple estimate)

Alkaline D cells typically provide high capacity at low-to-moderate loads. Actual runtime varies by device current draw, temperature, and cutoff voltage.

• Rule of thumb: runtime (hours) ≈ effective capacity (Ah) ÷ device current (A). In series packs, voltage adds but capacity does not.
• Example: If your lantern draws ~0.4 A from a series pack of D cells, and the effective capacity is ~10 Ah under that load, runtime ≈ 10 ÷ 0.4 = ~25 hours (actual results may vary).

Compatibility and fit

• Works in any device that specifies D, LR20, or 1.5 V alkaline D batteries.
• Typical D-cell size: about 61.5 mm length × 33.2 mm diameter (fits standard D compartments).
• Do not mix battery types or brands in the same device (avoid mixing alkaline with NiMH or mixing old with new).
• Observe polarity and insert in the order shown in the device.

Care, storage, and safety

• Store in a cool, dry place (room temperature is ideal). Do not refrigerate or freeze.
• Remove batteries from devices you won’t use for months to reduce leak risk.
• Do not attempt to recharge, disassemble, or incinerate.
• Keep out of reach of children. If a battery leaks, avoid contact with skin/eyes and follow device/battery cleanup guidance.
• Recycle where available; follow local disposal rules for alkaline batteries.

Alternatives

• Rechargeable NiMH D cells: Better for frequent use; higher upfront cost plus a charger, but lower long-term cost and waste.
• Lithium primary D (where available): Lighter and better cold-weather performance; typically higher cost and less common.

FAQ

Is the E95 Max rechargeable?

No. It’s a single-use alkaline battery. Use NiMH D cells if you need rechargeability.

How long will it last in my device?

It depends on the device’s current draw and conditions. Expect longer runtimes in low-to-moderate drain devices and shorter runtimes at high loads or in cold environments.

Can I store these for emergencies?

Yes. With up to a 10-year shelf life, they are suitable for emergency kits when stored properly.

What devices are not a good fit?

Very high-drain or daily-use devices may be more cost-effective with rechargeable NiMH D cells. For extreme cold, consider lithium options if compatible.
