Varta AAA Alkaline

Varta AAA Alkaline batteries deliver dependable 1.5 V power in a compact LR03 size. They are a practical choice for everyday devices that draw low to moderate current and benefit from long shelf life and broad availability.

Key specs at a glance

• Size/format: AAA (LR03)
• Chemistry: Alkaline (primary, non-rechargeable)
• Nominal voltage: 1.5 V
• Typical capacity: ~800–1200 mAh at low drain (less at higher currents)
• Shelf life: long (often up to 10 years when stored at room temperature; check date code)
• Operating range: works best from 0–35°C; performance drops in freezing temperatures

Best for

• TV/audio remotes and presentation clickers
• Wireless mice and keyboards
• Digital thermometers and small medical devices (check device manual)
• Small LED flashlights and headlamps
• Portable radios and sensors with intermittent use

Avoid or consider alternatives if

• High-drain devices (bright LED lights, motorized toys): prefer AAA NiMH rechargeables (1.2 V) for better sustained output and lower cost per use.
• Cold-weather or emergency kits (below 0°C/32°F): use AAA lithium primary batteries (1.5 V) for superior low-temperature performance and longer storage life.
• Heavy daily use: rechargeables (NiMH) reduce waste and ongoing cost.

Estimated runtimes (examples)

Actual runtime depends on device draw, cutoff voltage, and temperature. Use: Runtime ≈ Capacity (mAh) ÷ Device draw (mA).

Device	Typical draw	Example runtime per AAA
TV remote (intermittent)	Very low average	Often 1–2 years of typical household use
Wireless mouse	~10–20 mA average (varies widely)	~40–80 active hours; with sleep modes, weeks to months
Small LED flashlight	~100 mA	~6–10 hours to noticeable dimming
Portable radio	~30 mA	~20–30 hours

Compatibility notes

• Use wherever AAA / LR03 / 1.5 V alkaline is specified.
• Do not mix old and new batteries, or different brands/chemistries in the same device.
• If a device expects rechargeable AAA (1.2 V), alkalines may work but can shut off earlier under high load due to voltage sag.

Storage and care

• Store in a cool, dry place (50–77°F / 10–25°C). Keep in original packaging until use.
• Remove batteries from devices not used for 30+ days to reduce leakage risk.
• Insert with correct polarity (+/−). Never attempt to recharge alkaline cells.
• Recycle or dispose according to local regulations. Do not incinerate.

FAQ

Are Varta AAA Alkaline batteries rechargeable?

No. They are primary (single-use) cells. For recharging, choose AAA NiMH batteries with a compatible charger.

Will they work in cold weather?

They function in mild cold but lose capacity quickly below freezing. For sub-zero conditions, use lithium AAA primary batteries.

How long do they last in storage?

Alkaline AAA cells typically hold charge for many years when stored at room temperature. Check the package date code; replace if past the recommended “best before” date.

Is mixing battery types safe?

No. Do not mix brands, ages, or chemistries (alkaline, lithium, NiMH). Always replace the full set together.

What should I do if I see corrosion or leakage?

Power off the device, wear disposable gloves, and remove the batteries carefully. Follow the device manufacturer’s cleaning guidance and dispose of the cells per local rules.
