Frequently Asked Questions - CellPac LITE VARTA

How do I charge the CellPac LITE power bank?

Use the included Micro USB cable to connect the power bank to a USB power adapter (5V/2A recommended). The LEDs will blink during charging and stay solid when fully charged.

How many times can I charge my phone with a full CellPac LITE?

With a capacity of 5,000 mAh, it can charge a typical smartphone (e.g., 3,000 mAh battery) about 1.5 times, depending on phone model and usage.

Can I charge two devices simultaneously?

No, the CellPac LITE has only one USB output port, so it supports charging one device at a time.

How do I check the remaining battery level?

Press the power button (if available) or simply connect a device. The four LEDs indicate approximate charge: 1 LED = 0-25%, 2 LEDs = 25-50%, 3 LEDs = 50-75%, 4 LEDs = 75-100%.

Is the power bank safe to leave charging overnight?

Yes, the CellPac LITE has overcharge protection. However, it is recommended to unplug once fully charged to prolong battery lifespan.

What devices are compatible with the CellPac LITE?

Any device that charges via USB (5V) is compatible, including smartphones, tablets, Bluetooth headphones, cameras, and portable gaming consoles.

How do I clean the power bank?

Wipe the exterior with a soft, dry cloth. Do not use harsh chemicals or immerse in water. Keep the ports dry.

Can I take the CellPac LITE on an airplane?

Yes, power banks under 100 Wh (this model is ~18.5 Wh) are allowed in carry-on luggage. Check with airline for specific regulations.

What should I do if the power bank gets wet?

Immediately disconnect any cables, dry the exterior with a cloth, and place it in a dry area for 24 hours before attempting to use again. Do not open or charge while wet.

How do I dispose of the CellPac LITE properly?

Do not throw in household trash. Recycle it at designated battery collection points or electronic waste facilities.

1. Introduction of CellPac LITE

CellPac LITE is the standard range of lithium-rechargeable battery products from VARTA Storage GmbH.

We offer a range of pre-configured battery packs that are immediately available for standard applications. They are made exclusively from cylindrical or prismatic form-factor cells. CellPac LITE power packs are fitted with an electronic protective circuit module (PCM) with additional overcurrent protection. All cells used comply with the requirements of the safety standard UL1642 and many packs are certified to additional safety standards UL2054 or IEC62133. These are a complete battery solution, complete with the necessary cables and connectors that are ready for use.

SYSTEM HIGHLIGHTS OF VARTA Storage CellPac LITE BATTERIES:

Excellent energy density	Good cycle-life (500 full cycles typically)
Variety of form-factors	Low self-discharge
High cell voltage (~3.7 V nom.)	IEC62133-2:2017 certification for most of the packs
UL2054 listing for EasyPack batteries	Wide temperature range
Charging technique compatible with Li-Ion (const. I / const. V)	ISO9001 certified for design and manufacture

ENERGY DENSITY FOR RECHARGEABLE BATTERY SYSTEMS

Comparison of different rechargeable battery systems regarding their energy densities

1.1 Definitions and Standards

BASICS

Unless otherwise stated the technical values and definitions are based on room temperature conditions (RT = 22°C ± 3°C).

SYSTEM - SPECIFIC DATA

The gravimetric energy density depends on battery size and ranges from approx. 170-200 Wh/kg and the volumetric energy density ranges from approx. 350-450 Wh/L incl. PCM.

VOLTAGE DEFINITIONS

Open Circuit Voltage (OCV): Equilibrium potential 3.0 V to 4.2 V on average, dependent on temperature, storage duration and state of charge. Nominal Voltage is typically 3.7 V, see specifications for individual batteries.

End of Discharge Voltage (VE): The voltage at the end of discharging is 2.75 V to 3.2 V per cell, depending on discharge rate and temperature. End of Charge Voltage: Terminal voltage after charge is 4.2 V.

CAPACITY DEFINITIONS

The capacity C of a cell is defined by the discharge current I and the discharge time t: C = I * t I = constant discharge current t = duration from the beginning of discharge until the end of discharge voltage is reached

Rated Capacity: The rated capacity C denotes the energy amount in mAh (milli-Ampère hours) that the cell can deliver at the 5h discharge rate (0.2 CA). The reference temperature is +22°C ± 3°C, and the final discharge voltage 3.0 V.

Available Capacity: Factors which affect the available capacity are:

Rate of discharge
End of discharge voltage
▶ Ambient temperature
State of charge
Age
Cycle history

At higher than nominal discharge rates the available capacity is accordingly reduced.

CURRENT DEFINITIONS

Charge and discharge rates may be given as multiples of the Rated Capacity (C) in Ampères (A) with the term CA.

Example:

Rated Capacity C = 1000 mAh

0.1 CA = 100 mA, 1 CA = 1000 mA

Nominal Discharge Current: The nominal discharge current of a CellPac LITE battery is the 5 hour discharge current (0.2 CA). It is the current at which the nominal capacity of a cell is discharged in 5 hours.

I = C/t = C/5 = 0.2 CA when t = 5 h

3. Charging / Discharging

3.1 Charging

Fast charging can be achieved in a temperature range of 0 ... +45°C.

The current of charging needs to be limited to individual specification of the battery selected. Limiting factors may be the PCM, wire connector assembly or the cell itself.

In order to avoid overcharging along with damaging the battery or even hazardous situations, the charging voltage has to be limited strictly to 4.2 V per cell, see the individual specification for your battery choice for the most in detail information. It is recommended to terminate the charging either after 3hrs and/or after the charging current falls below 0.02 C.

The charging process is illustrated below showing current and voltage of a LPP 443441 S battery using 1 C charging.

Example cell charging characteristics

3.2 Discharging

Since all CellPac LITE batteries are delivered with a safety-circuit the maximum current rating established in the specification must be observed. There are two levels of overcurrent protection of which the first one will lead to a reversible interruption of current supply, while exceeding the second level will make the battery unusable permanently.

Please see the individual Product Information sheets for details of the safety parameters built into our modules which are set differently depending on the type designation.
