Capacity:

The capacity, measured in milliampere-hours (mAh), indicates how many amps the battery can hold. Opt for a higher capacity for longer device runtimes between charges.

Voltage:

Ensure the battery voltage matches your device's requirements. batteries typically offer a nominal voltage of 3.6 volts per cell. At MaxAmps we are able to build lithium-ion batteries at a wide range of voltages by putting cells in series. Contact us with what voltage is required and we can help find the right battery for you.

Chemistry:

Lithium-ion (Li-ion) batteries are a great option for lower discharge applications that are looking for long runtimes because of their high energy density. However, consider alternatives like lithium iron phosphate (LiFePO4) for applications prioritizing safety and longevity. Or Lithium Polymer for applications that require high discharge.

Brand Reputation:

Stick to reputable brands known for quality and reliability. Trusted manufacturers often invest in rigorous testing and quality control measures.

Brand / Manufacturer

The first thing to consider when choosing an battery for your device or project is the battery brand. Not all brands are created equal and often times you will find are not very truthful in their battery ratings. This is especially true when discussing the Chinese re-wrapping brands. The goal of any manufacturer or brand is to sell as many batteries as possible but some companies have been known to exaggerate their ratings to appear to offer a better product than the other. This practice of exaggerating battery specs is unlawful and can be very dangerous to consumers if gone unchecked. Thankfully, there is a watchdog in the lithium ion battery industry known as the battery mooch who provides thorough testing and will call out these companies for their unlawful practice.

There are five major brands that manufacturer batteries who you can rely on to provide quality, consistent and truthfully rated batteries and those brands are; LG Chem, Molicel, Samsung, Sony|Murata and Panasonic|Sanyo. These brands are well established and have long standing tradition, values and standard to uphold. Any manufacturer specs provided by these brands is well documented and tested many times over. You will often see the battery outperform the manufacturer ratings put forward from these brands.

Other brands such as Efest, Vapcell, Imren and MXJO have been established for a few years and their quality has certainly improved. These brands tend to slightly exaggerate the battery ratings for their products in an effort to appeal to the consumer and sell more. It should be noted these companies do not actually produce their own lithium ion battery but instead purchase them from other manufacturers and then wrap the battery and add packaging to make the battery suitable for retail sale. They do often provide value by using a thicker PVC wrap on the battery which provides an extra layer of protection. As well these brands often include a battery carrying case with all of their batteries.

There are various other unknown brands with all sorts of unrealistic ratings. As of , there is not a single lithium ion battery rated above mAh capacity or a 30A CDR. If you see any battery marketed above these specs, you should be very weary of what you are actually getting as it is absolutely certain to be false and exaggerated.
