Frequently Asked Questions - LCD Multi Charger+ 57681 VARTA

What types of batteries can I charge with this charger?

This charger is designed for NiMH rechargeable batteries only (AA and AAA sizes). Do not charge primary (non-rechargeable) batteries as they may burst.

How long does it take to charge a battery?

Charging time depends on battery capacity. For a 1000 mAh cell, it takes approximately 6.5 hours, while a 550 mAh cell takes about 2 hours.

What do the LCD display symbols mean?

The display shows the state of charge using quarter circles: 1 quarter = 1-25%, 2 = 26-50%, 3 = 51-75%, 4 = 76-100%. A flashing symbol may indicate a defective battery or error.

Can I charge different battery capacities or sizes together?

Yes, each slot is independent. You can mix AA and AAA batteries of different capacities, but charging times will vary.

Is it safe to leave batteries on the charger overnight?

The charger has overcharge protection (safety timer and -ΔV cut-off), so it is safe to leave batteries overnight. However, it's best to remove them once fully charged.

What should I do if the display shows an error symbol?

An error symbol (no segments or a specific icon) may indicate no contact, wrong polarity, or a defective battery. Reinsert the battery correctly or replace it.

Can I charge lithium-ion batteries with this charger?

No, this charger is only for NiMH batteries. Charging lithium-ion batteries may cause overheating or fire.

Is the charger compatible with worldwide voltages?

Yes, the charger accepts 100-240V AC input, so it can be used worldwide with an appropriate plug adapter.

How should I clean the charger?

Unplug the charger and wipe it with a dry cloth. Do not use water, cleaning solvents, or abrasives.

What safety features does the charger have?

It includes reverse polarity protection, defective battery detection, overcharge timer, and -ΔV cut-off to prevent overcharging.

The relative capacity is calculated within the charger by using the charging time and current. Due to systemic reasons, NIH cells can provide only few reference points for the exact determination of the state of charge. Therefore, under certain circumstances, the percentages on the display can change faster than expected. The timer protects the rechargeable batteries from overcharging. Interrupting the power supply restarts the timer. Charging control function protects the batteries from overcharging. Remove the batteries when the charger is unplugged.
