Battery capacity, measured in milliamp-hours (mAh), indicates how long a device operates before needing a recharge; higher mAh means longer usage.
Think of mAh as the size of a fuel tank – larger tanks allow longer runs between refills. For example, a mAh battery can deliver milliamps for one hour or milliamps for five hours.
High-capacity lithium-ion batteries offer key benefits, such as:
Currently, and are the most popular lithium-ion battery cells on the market.
The battery is an excellent choice for rechargeable lithium-ion cells.
Top high-capacity options include the Panasonic NCRG, LG INR-M36, Sanyo NCRGA, LG MJ1, Molicel M35A, and Samsung 35E (mAh). These batteries offer a good balance of capacity, cost, and availability for various uses.
You may find some cells labeled “mAh,” but here is the truth:
As a custom battery pack manufacturer working with trusted brands, we are cautious about cells claiming over mAh; anything over mAh is likely too good to be true. We ensure thorough inspections so you receive genuine batteries from trustworthy sources!
Switching from to batteries marks a significant advancement in the battery world, driven by the demand for more power and better performance.
The cells boast over mAh, surpassing the power of the reliable old s. If you’re curious about what distinguishes these batteries, explore “ vs ” for details on cost, performance, and application.
The Samsung 50E and Panasonic NCRA are with the highest capacity, each offering a substantial mAh – renowned for their energy capacity and reliability. They’re excellent for high-power flashlights, e-bike packs, and portable power stations. Many are transitioning from to these more robust battery packs and Tesla was one of them.
When aiming to make a lithium-ion battery with the highest capacity, you must first consider size constraints. It’s also important to consider the continuous discharge rating (CDR), which indicates how much current (measured in amps) the battery can safely provide without overheating or damaging itself.
Here are some tips to determine if the battery is suitable:
For maximum runtime:
For high-drain devices:
Truth: Not possible with current Li-ion chemistry.
Truth: Samsung 50E (mAh) lasts shorter than Molicel P50B in 20A+ tools due to voltage sag.
Truth: Tesla stores 5% less energy than but charges 3X faster with a tabless design.
Charge cycles depend on battery quality, usage, and depth of discharge. High-quality batteries usually provide 300-500 full charge cycles before significant capacity loss, with some premium versions claiming up to cycles.
A lithium battery cannot be classified solely by capacity, as each application has unique requirements. The best battery is the one that meets those specific needs.

A mAh capacity rating is available across several battery chemistries, each tailored to specific applications based on performance, weight, and durability:
Lithium-Ion (Li-ion): Known for high energy density and lightweight design, Li-ion batteries are widely used in smartphones, laptops, and cameras. They offer long cycle life and excellent rechargeability, making them ideal for everyday electronic devices.
Lithium Polymer (LiPo): LiPo batteries offer similar performance to Li-ion but with added flexibility in shape and weight. Their slim profiles make them ideal for drones, tablets, and compact electronics. While efficient and lightweight, they require careful handling to prevent damage or overheating.
Nickel-Metal Hydride (NiMH): Although heavier and with lower energy density than lithium-based options, NiMH batteries are durable and cost-effective. Common in devices like flashlights and game controllers, they handle moderate-to-heavy use well and provide consistent performance.
Lithium Iron Phosphate (LiFePO₄): Praised for exceptional stability and safety, LiFePO₄ batteries have a longer lifespan and are ideal for high-demand applications such as electric vehicles, solar storage systems, and industrial tools. Their heavier weight is offset by their robust performance and reliability.
Each battery type offers unique advantages, and the best choice depends on your device's requirements for energy output, form factor, and durability.
Voltage plays a crucial role in determining a battery's compatibility with different devices, even when capacity remains the same. Here are the most common voltage levels for mAh batteries and their typical uses:
3.7V: Standard for single-cell Li-ion and LiPo batteries, this voltage is ideal for compact electronics like smartphones, handheld gaming consoles, and Bluetooth speakers. It provides efficient power delivery while maintaining a lightweight form.
7.4V: Found in dual-cell configurations, 7.4V batteries are commonly used in drones, remote-controlled vehicles, and high-performance cameras. They deliver more power than a single-cell setup, making them suitable for devices that require higher energy bursts.
12V: Typically used in specialized or industrial-grade equipment, 12V mAh batteries are seen in applications like portable medical devices, surveillance systems, or compact backup power supplies. Their higher voltage supports steady performance where consistent output is critical.
The shape of a mAh battery influences how well it fits into a device and performs under different conditions:
Cylindrical Cells: Common in Li-ion and NiMH batteries, these cells are durable and structurally strong. They're often used in power tools, flashlights, and medical devices where ruggedness and consistent output are essential.
Pouch or Prismatic Cells: Typical of LiPo batteries, these flat, lightweight designs are ideal for space-constrained devices like drones, tablets, and slim electronics. Their flexible form allows for custom configurations and efficient use of internal space.
Rectangular or Block Cells: Frequently found in LiFePO₄ or industrial-grade Li-ion batteries, these shapes are tailored for equipment that demands high stability and power density, such as backup power units or electric mobility systems.
The markings "S" and "P" on a battery describe how its individual cells are arranged:
"S" (Series): Indicates the number of cells connected in series to increase the overall voltage. For example, a 3S configuration means three cells in series—if each cell is 3.7V, the total voltage becomes 11.1V (3.7V × 3).
"P" (Parallel): Refers to cells connected in parallel to increase the total capacity while maintaining the same voltage. A 2P setup means two cells are connected in parallel, so if each cell is mAh, the combined capacity is mAh.
The cost of a mAh battery can vary significantly depending on several key factors:
Battery Type: Li-ion and LiPo batteries tend to be more expensive than NiMH due to their higher energy density and longer service life.
Brand and Quality: Reputable manufacturers typically charge more for batteries that undergo strict quality control and meet safety standards.
Additional Features: Built-in protections such as overcharge prevention, thermal regulation, and smart monitoring systems can increase the price.
A mAh battery's lifespan depends on its usage, but typically, it can power a smartphone for 8-12 hours of moderate usage or a Bluetooth speaker for up to 12 hours. In high-demand devices like drones or power tools, it may only last a couple of hours.
Higher capacity generally means longer runtime, but it's not always the ideal choice. Larger-capacity batteries tend to be bulkier and heavier, which can limit their compatibility with compact devices. If your device doesn't require extended power, opting for a high-capacity battery may add unnecessary size and weight without practical benefits.
Selecting the right mAh battery involves balancing factors like battery chemistry, form factor, voltage, and specific application. Lithium-ion and LiPo options offer lightweight, high-density power for portable electronics, while NiMH and LiFePO₄ are better suited for tools, industrial systems, or environments where durability and safety are priorities.
