As a professional custom lithium ion battery packs supplier, CMB has witnessed exponential growth in the use of lithium batteries across various industrial applications. The market offers a wide array of rechargeable lithium-ion batteries, each type with its unique characteristics and advantages. Choosing the best rechargeable batteries will boost the performance, safety, and longevity of your devices or systems.
Some people will choose the used batteries, especially for home storage systems because of the cost considerations. At CM Batteries, we believe in the importance of using high-quality new batteries. It not only ensures better performance but also aligns with our commitment to safety for our customers, and community, and responsibility for the planet.
Types of Rechargeable Lithium-Ion Batteries
The lithium-ion batteries are used for diverse applications, offering solutions tailored to different needs. The most common rechargeable battery types are included:
NiCd (Nickel-Cadmium) Batteries
NiCd batteries represent an older technology in the rechargeable battery. These batteries are relatively cheap due to their susceptibility to “memory” effects. To maintain optimal performance, NiCd batteries should be fully discharged before recharging. They have a lifespan of approximately 1000 charge cycles, which equates to about three years of daily use. NiCd batteries typically have a lower voltage compared to Li-ion batteries.
NiMH (Nickel-Metal Hydride) Batteries
NiMH batteries are more expensive than NiCd batteries but offer greater flexibility in usage. They can be partially discharged and recharged up to about 1000 times without losing capacity. NiMH batteries provide a significantly larger capacity compared to NiCd batteries, which they have largely replaced in the market. Their widespread use has made both NiMH batteries and compatible chargers readily available.
Li-ion (Lithium Ion) Batteries
Li-ion batteries reform the limitations of both NiCd and NiMH technologies, offering full voltage and freedom from memory effects, which are high-capacity rechargeable batteries, However, they are not available in standard voltages for most sizes, except 9V batteries. AAA, AA, C, and D-size Li-ion batteries typically provide 3.7V instead of the standard 1.5V. Li-ion batteries require specialized chargers for safe and effective charging.
Lead-Acid Batteries
Lead-acid batteries are one of the oldest types of rechargeable batteries. They are commonly used in automotive applications, uninterruptible power supplies, and large-scale energy storage systems. Lead-acid batteries are known for their reliability, low cost per watt-hour, and ability to supply high surge currents. They have a relatively low energy-to-weight ratio and energy-to-volume ratio compared to more modern battery technologies. Lead-acid batteries require regular maintenance in the form of water replenishment for flooded types, although sealed varieties are also available. These batteries have a lower depth of discharge compared to other rechargeable types, typically around 50% to maintain longevity. Despite their lower energy density, lead-acid batteries remain popular in applications where weight and size are not primary concerns due to their cost-effectiveness and established technology.
What Are the Best Rechargeable Batteries？
This table can help you understand which are the best rechargeable batteries, and the best rechargeable batteries often depend on the needs of your device

| Lithium Rechargeable | 2 to 4 years | 600 to 1000 | Varies(Slow)1 hour(Fast） | 90(Gravimetric density)210(Volumetric density) | 40℉ to 140℉(-40℃ to 60℃) |
| Nickel Cadmium | 1.5 to 3 years | 1000+ | 4-10 hours(Slow)0.25-1 hour(Fast) | 50(Gravimetric density)140(Volumetric density) | 22℉ to 140℉(-30℃ to 60℃) |
| Lead Acid | 6 months | Varies | 24 hours(Slow)3-5 hours(Fast) | 30-50(Gravimetric density)30-90(Volumetric density) | 77℉ to 92℉(25℃ to 33℃) |
Of the four types of lithium-ion batteries we have shown, each battery chemistry has its advantages and disadvantages in terms of shelf life, cycle life, charge time, energy density, and operating temperature.
For example, the NiMH battery is the longest-lasting rechargeable battery for the floor sweeper, The 21700 lithium battery is best suited for e-bikes and has the longest and safest life. The specific requirements and applications will determine your personalized battery pack solution with the different chemistries cells. The article “Unveiling the Unique Characteristics of Different Lithium-Ion Battery Types” provides a detailed comparison of each type of lithium-ion battery.
The Factors for Selecting the Best Rechargeable Batteries
When we choose rechargeable batteries for our applications, we should consider serval factors.
a) Energy Density: The amount of energy storage per unit volume or weight will be a constraint for battery pack solutions.
b) Power Density: This refers to how quickly energy can be delivered for high-drain applications.
c) Cycle Life: The number of charge & discharge cycles a battery can undergo capacity loss.
d) Safety: Different chemistries have varying safety profiles, which is particularly important in consumer products or large-scale installations.
e) Temperature Performance: Some batteries perform better in extreme temperatures and it is important for outdoor or industrial applications.
f) Cost: While initial cost is a factor, it’s important to consider the total cost of ownership, including lifespan and efficiency.
Second-Hand Batteries vs. High-Quality Rechargeable Batteries
The battery market is very confused with the situation of the suppliers who sell second-hand batteries of the best quality to assemble battery packs in the market. It brings risks and concerns. The customers not only consider the cost but also are willing to get professional knowledge on custom battery pack assembly, battery pack knowledge, the materials knowledge of the cells, BMS, the nickel strap and battery pack assembly and design woodcraft, etc. The cells are the heart of the battery pack. What is more, the welding and disassembly cells are named used batteries. They prohibit assembling battery packs.
Second-hand batteries with several risks:
- They cause battery pack leakage or explosions.
- The second-hand batteries also damage your brand and lose your customers.
To protect your brand, please care the quality.
Using Second-Hand Batteries Tends To Become More Expensive
High-quality batteries undergo stringent testing and adhere to strict manufacturing standards to meet safety requirements. The poor quality batteries will affect the use of electronic devices with shorter battery life. In addition, poor-quality batteries may also damage the devices, leading to extra expenses for repair or replacement.
While they may have a higher cost compared to their Second-hand battery, their superior performance and longer lifespan make them a smart investment. By choosing high-quality batteries, you can avoid the cost of replacements and repairs. Additionally, high-quality batteries provide you with peace of mind and further financial protection.
To mitigate these risks and ensure the best performance, it is essential to prioritize the use of high-quality batteries.
