Varta AA Alkaline

Varta AA Alkaline: reliable single-use power for everyday devices

Varta AA Alkaline batteries are primary (single-use) 1.5 V cells sized for common household electronics. They deliver steady power for low- to moderate-drain devices and store well for emergencies.

When to choose these batteries

• Remote controls, wall clocks, basic toys, handheld remotes, and small sensors.
• LED flashlights on low/medium settings and portable radios.
• Emergency kits where long shelf life and readiness matter.
• Devices that are used intermittently (standby most of the time).

When to consider alternatives

• High-drain or frequent use (e.g., gaming controllers, digital cameras, high-output flashlights): choose NiMH AA rechargeables (typically 1900–2500 mAh) to reduce cost and waste over time.
• Very cold conditions or long-term emergency gear: choose lithium AA (Li-FeS2, 1.5 V) for better low-temperature performance and lighter weight.
• Devices that specify rechargeable cells only: use NiMH per the manual.

Key facts

Size	AA (LR6, AM3)
Chemistry	Alkaline (zinc–manganese dioxide)
Nominal voltage	1.5 V
Type	Primary (single-use; not rechargeable)
Typical capacity	~1800–2850 mAh at low drain (capacity decreases at higher loads and in cold)
Shelf life	Long shelf life when stored cool and dry; check packaging date code
Operating notes	Best at room temperature; performance drops in sub‑freezing weather
Environmental	Modern alkaline cells are generally free of added mercury and cadmium; follow local recycling rules

Example runtimes (per cell)

Device	Approx. draw	Estimated runtime
Wall clock	0.2 mA	1–2 years
TV remote	~1 mA average (peaks when pressing)	6–12 months
Wireless mouse	5–15 mA average	1–3 months
LED flashlight (medium)	150–250 mA	2–6 hours

Quick estimate: runtime (hours) ≈ capacity (mAh) ÷ device draw (mA) × 0.7–0.9 to account for alkaline performance under load. Actual results vary by device and temperature.

Compatibility notes

• Works in any device that specifies AA, LR6, or AM3 alkaline batteries.
• Some smart locks and sensors expect 1.5 V cells; NiMH (1.2 V) may reduce runtime—check the device manual.
• Install in matching sets; do not mix old and new or different chemistries in the same device.

Storage and safety

• Store in a cool, dry place (50–77°F / 10–25°C). Avoid heat, humidity, and direct sun.
• Keep in original packaging or a battery case; avoid loose contact with metal objects.
• Remove batteries from devices that will sit unused for 60+ days to reduce leak risk.
• Never attempt to recharge, short-circuit, or incinerate alkaline batteries.
• If leakage occurs, avoid skin contact and follow device manufacturer guidance for cleanup and disposal.

FAQ

Are Varta AA Alkaline batteries rechargeable?

No. They are primary alkaline cells and must be replaced when depleted.

How long do they last in storage?

Modern alkaline batteries hold charge for many years when stored properly. Check the package for a best-before date and use older stock first.

Do they work in cold weather?

They will power devices in cool conditions but with reduced capacity and voltage under load. For sub‑freezing use, lithium AA is a better choice.

Are they safe for children’s toys?

Yes, when used as directed and the battery compartment is secured. Replace all cells at once and dispose of used batteries promptly.

Can I mix brands or old and new cells?

No. Mixing can cause leakage and poor performance. Replace all cells in a device at the same time with the same type and brand.
