Li-Ion Batteries – Powerful Energy for E-Bike, Tools and More
Lithium-ion batteries dominate many applications today – from the e-bike world over cordless tools to power banks and RC models. The high energy density and low self-discharge make them the first choice when you need maximum performance at light weight. Typical voltages range from 7.2 volts (for small RC cars) to 72 volts (for e-mobiles). Capacities ranging from 1.5 Ah to 30 Ah cover different runtimes. When selecting, pay attention to compatibility with your device: many manufacturers rely on proprietary plug systems, while others use standardized formats such as 18650 cells. Check the product specifications for voltage, capacity, and cell typeto avoid surprises.
Particularly popular are batteries with integrated battery management system (BMS), which prevents overcharging and deep discharge. In this category you will find models such as the "Li-Ion battery, 18 volts, 2.0 Ah" or high-performance "Power Racing 50C – 6700mAh – 3S – 11.1V" for RC sports. If you are looking for a replacement battery for your e-bike, complete housing solutions are available as frame, rear rack, or side-click batteries.
NiMH batteries – Reliable and rechargeable for everyday use
Nickel-metal hydride (NiMH) rechargeable batteries are the proven choice for devices with moderate power requirements – from remote controls and flashlights to toys and cordless phones. They are more environmentally friendly than disposable batteries and offer low self-discharge, especially in modern 'Ready-to-Use' types. In this category you will find formats such as Mignon (AA), Micro (AAA), 9V block and special sizes. The NiMH rechargeable batteries are often available in sets with chargers – for example, the 'USB fast charger for 4 AA / AAA NiMH rechargeable batteries including 4 ReCyko Mignon (AA) NiMH rechargeable batteries with 2600 mAh'.
A typical product is the 'Recharge Ultra Mignon (AA) NiMH rechargeable battery with 2500 mAh – 2 pieces'. With 2500 mAh, these cells last significantly longer in a digital camera or cordless trimmer than standard batteries. Please note: NiMH rechargeable batteries have a nominal voltage of 1.2 volts, while disposable batteries provide 1.5 volts. Some devices still work perfectly, while others indicate a low battery early. Check compatibility in your device's instruction manual.

High-capacity AA rechargeable batteries for long-lasting energy in everyday life.
Tips & Worth knowing
Correctly distinguishing battery types
The chemical composition determines voltage, capacity and safety. Li-Ion batteries (3.6–3.7 V nominal voltage) deliver high currents and are lightweight. NiMH batteries (1.2 V) are more robust and cheaper. For stationary applications such as alarm systems, lead-fleece batteries are also used. Read the product specifications regarding cell type before purchasingto make the right choice.
Capacity and voltage – what matters?
Capacity (mAh/Ah) indicates how long a battery can deliver a specific current. For a cordless screwdriver, 2–4 Ah is often sufficient; for an e-bike, 10–14 Ah is common. The voltage (volts) must match your device – too high a voltage can cause damage. Check compatibility based on the information on your old battery or in the operating instructions.
The right charger
A suitable charger extends the life of your battery. In the subcategory Battery Chargers you will find simple plug-in chargers, but also intelligent universal chargers with LCD and microprocessor control. For NiMH, chargers with individual slot monitoring are recommended; for Li-Ion, those with a balancer function. Only use chargers that are designed for your battery type – an incorrect charging current can lead to overheating. Further tips on selecting cordless tools can be found in the blog article “The right cordless screwdriver: buying guide and application tips”. Also the „Cordless Power Tool Test & Comparison 2026“ offers orientation for tool buyers.

Frequently Asked Questions
What is the difference between Li-ion and NiMH batteries?
Li-ion batteries have a higher energy density and a nominal voltage of 3.6–3.7 volts, while NiMH batteries are at 1.2 volts. Check the respective product specifications for the properties and certifications important for your selection. Both battery types are rechargeable but require specific chargers. In this category you will find both Li-ion and NiMH batteries in various formats and capacities.
How do I choose the right capacity (mAh/Ah) for my battery?
Capacity determines runtime. For a cordless screwdriver, 2–4 Ah is often sufficient; for an e-bike, 10–14 Ah is common; for RC models, 4000–6000 mAh may be optimal depending on driving style. Also note the voltage: your device only tolerates a specific voltage. The products in this category range from 1.5 Ah (for small tools) to 30 Ah (for e-mobiles). Check the product specifications to find the right capacity.
Can I charge a NiMH battery with a Li-ion charger?
No, you should definitely avoid that. Li-Ion chargers provide a different charging termination voltage and often a higher current, which can overheat or damage NiMH batteries. Always use a charger designed for your battery type. In the subcategory 'Battery Chargers' you will find specific chargers for NiMH and Li-Ion, some also as universal chargers with switchable mode.
How long does a battery last on average?
The lifespan is measured in charge cycles. Li-Ion batteries typically last 300–500 full cycles, NiMH batteries about 500–1000 cycles, before the capacity noticeably decreases. Factors such as deep discharge, overcharging, and high temperatures shorten the lifespan. Modern batteries with BMS (Battery Management System) protect against premature wear. In the category you will find both standard and high-quality cells. Check the manufacturer's specifications for cycles.
Can I use batteries of different capacities in parallel?
That is not recommended. If batteries of different capacities are combined in a device (for example in a battery pack), they discharge unevenly, which can lead to deep discharge and damage. Always use batteries of the same capacity, same type, and preferably the same age.
In summary
The category 'Batteries' includes 327 items and is divided into four subcategories: Battery Chargers, E-Bike Batteries, Li-Ion Batteries, and NiMH Batteries. The range extends from standard AA/AAA batteries to high-performance LiPo cells for RC sports to complete e-bike battery packs with voltages from 24 V to 72 V and capacities from 1.5 Ah to 30 Ah. Additionally, you will find suitable chargers, power banks, and replacement batteries for electric mobility devices, tools, and consumer electronics. Before purchasing, check the compatibility with your device based on the voltage and connector specifications.
