Am hoping Colin has a professional opinion on small batteries of the 18650 & larger cyclindrical types as to experience of Top / Middle / don't touch em with @Mart s bargepole brands?

But those here who have chanced their arm & had good results.. feel free to make some specific recommendations.
Would be good to have a better overview of brands, quality control & capacity claims, seeing as so many gadgets are li- chemistry based nowadays.

Singular or bulk buying an unknown brand is akin to the trauma of a british seaside ocean plunge.
Yet a bigger name brand battery purchase may outweigh the value of tentative repair of broken / tired kit.

Prominent manufacturers such as Panasonic, Sony, and LG are renowned for the reliability and performance of their 18650 cells.

Their adherence to stringent manufacturing standards often ensures the actual capacity aligns with the advertised specifications. These brands invest significantly in research and development, which often culminates in a superior product. Their cells typically feature sophisticated chemistry, meticulous quality control, and advanced safety mechanisms, reducing the likelihood of cell failure or thermal runaway incidents.

Mid-tier manufacturers such as Samsung and Sanyo can also produce competent products. Their batteries often offer a balance between cost-effectiveness and reliability, making them an acceptable choice for less critical applications.

However, caution should be exercised when considering lesser-known brands such as UltraFire or TrustFire. Although their pricing may be attractive, they often fall short in areas of performance, capacity consistency, and safety standards. It's akin to the adage "penny wise, pound foolish." The initial savings may be negated by frequent replacements or potential device failures.

Bulk buying from unknown brands tends to be a risky endeavor due to potential inconsistencies in quality control, capacity claims, and safety measures.

The procurement of well-established brand batteries might seem more expensive upfront, but their superior performance, safety standards, and longevity often justify the initial investment. It's a matter of holistic evaluation - the total cost of ownership (which includes replacement costs, potential device damage, and the risk of cell failure) as opposed to just the upfront cost.

In essence, the key to successful battery procurement lies in a careful brand evaluation, with emphasis on reliability, proven performance, and safety standards.
