Batteries – How to Choose the Right Power Source

Car batteries – cranking power and capacity

Capacity measured in ampere-hours (Ah) determines how long the battery can power electrical systems without recharging. Cold cranking amps (CCA) indicate the ability to start the engine in cold weather – petrol engines typically need 400-500A, while diesels require over 600A. AGM technology offers superior durability for vehicles with start-stop systems and extensive electronics.

When replacement is needed

If the engine struggles to start especially in the morning, lights dim during ignition, or the battery is over 4-5 years old, it's time for a replacement. Check the terminals – white or greenish deposits around the clamps signal corrosion and possible electrolyte leakage. Brands like BOSCH and HELLA offer extended warranties because they use high-quality lead alloys.

Mobile device batteries and power banks

Capacity is expressed in milliampere-hours (mAh) – devices with 5000mAh or more can fully charge a modern smartphone at least twice. Pay attention to output current: chargers with 2A will charge your device twice as fast as those with 1A. Brands like Cellular Line, Hoco and Konfulon offer compact designs with overcharge and short-circuit protection.

USB standards and fast charging

Quick Charge and Power Delivery technologies can charge a phone to 50% in 30 minutes, but require compatibility of both device and charger. Car chargers such as the Cellular Line ARUSB iPhone car charger must match the current your device supports – check your phone manufacturer's specifications before purchasing.

Tool and garden equipment batteries

Li-ion batteries are standard with brands like BOSCH, Einhell and GARDENA because they don't lose capacity when idle. Voltage determines power: 18V systems cover most household tools, while professional applications require 36V or higher. It's worth investing in a single manufacturer's system where the same battery powers multiple different devices.

Maintenance and storage

Store li-ion batteries at half charge if you won't use them for more than a month – this extends cell lifespan. Avoid fully discharging the battery before recharging as this damages the chemical structure. Brands with quality temperature control systems, like Karcher and Black & Decker, provide longevity and safety during intensive use.
