Varta EasyPack 2000

The Varta EasyPack 2000 is a compact 2000 mAh lithium‑polymer (rechargeable Li‑ion) battery pack designed for professional handheld devices that need reliable power in a tight space. An integrated protection circuit helps guard against overcharge, over‑discharge, short‑circuit, and overheating for safer operation and longer service life.

Quick facts

When to choose this pack

• Use if you need a small, protected pack for handheld electronics with moderate average current draw.
• Use for devices that run several hours per charge at 100–500 mA average load.
• Avoid if your design requires multi‑cell higher voltage, very high surge currents, or operation in extreme temperatures outside Li‑ion norms.

Runtime planning

Estimate runtime with: runtime (hours) ≈ (capacity in mAh × system efficiency) ÷ average load in mA.

• Light use (100 mA): ~17 hours at 85% system efficiency
• Typical handheld (250 mA): ~6.8–7 hours at 85% efficiency
• Higher load (500 mA): ~3.4 hours at 85% efficiency

Actual results depend on device duty cycle, wireless radios, screen brightness, and regulator efficiency.

Charging and safety

• Use a CC/CV charger set for lithium‑ion chemistry; do not trickle charge.
• Follow the charger’s recommended charge current; stop using any pack that shows swelling, odor, or damage.
• Do not puncture, crush, short, or expose to fire or temperatures outside the charger/device specifications.
• Charge in a well‑ventilated area and avoid charging unattended.

Integration notes

• Verify connector type and pinout; match polarity to your device harness.
• Confirm your device supports the expected single‑cell Li‑ion voltage range (roughly 3.0–4.2 V); check the device manual.
• If your device requires temperature sensing or an ID line, order a pack configuration that provides the correct signals.

Care and storage

• For storage over a month, keep at 30–60% charge in a cool, dry place (about 59–77°F / 15–25°C).
• Avoid full discharge; recharge when the device signals low battery.
• Top up every 3–6 months during storage to maintain health.

FAQ

Alternatives

If you need longer runtime, consider a higher‑capacity pack or adding a second pack in a design that supports it. If your device requires higher voltage, choose a multi‑cell Li‑ion solution specified by the manufacturer.
