Design & Development

The Key To Advanced Battery & Charger Performance


Robust Core Technology

Maha holds a decisive advantage by having the ability to design its own microcontrollers. This core technology allows Maha to quickly respond to market demands with never-before-seen features.

Market and Technology Driven R&D

Maha undertakes two distinct routes in product research and development: market and technology driven. As an active player in the market, Maha's product management teams constantly listen to customer's feedback and design products to address their needs. On the other hand, Maha also invests strongly to improve fundamental technology in order to enhance performance and reduce cost.

Above-and-Beyond Safety

Maha meets and exceeds safety requirements regulated by agencies such as UL, CE, GS, C-Tick, PSE, etc. In many of the products, customers can expect multiple-redundant safety protections.


Design robustness is verfied through accelerated life testing such as 25G HALT with thermoshock from -40 to 80 deg C.



Production & Testing


Maha operates a state-of-the-art manufacturing hub in Taiwan, using highly automated production and testing equipment to achieve high yields and throughput while maintaining a competitive cost. All facilities are certified by ISO-9001, as well as UL, TUV and various other accreditation agencies.

Every Maha product is tested individually by various automated testing systems eliminating the human factor in quality control. All products also undergo a rigorous burn-in/cycling sequence. Random sampling of in-production goods are subject to additional stringent reliability and aging tests.


Our Story

“Maha” means infinity in English. However, the story of Maha Energy was not with a glorious beginning, nor with a big entrance. Instead, this is a story about a young couple with two little boys, first generation immigrants realizing their American dream. Maha Energy, a minority woman-owned small business with great ambitions to provide better power solutions that gives a better environment for our future generations.

Being one of first to introduce the NiMH battery technology and tailor-made professional-grade chargers, Powerex brand has earned its recognition through years of hard work. Charles, armed with his Electrical Engineering degree, designed the legendary MH-C777 Universal Charger (product link) that allowed users to move the charging contacts to charge any of their batteries.  Next was the MH-C9000 (product link) WizardOne charger analyzer that allowed the user full adjustability for charging and analyzing AAA and AA batteries.  Continuing on, the company focused development of professional grade chargers for users that demand the highest performance.  At the same time, the company focused on improving performance of the NiMH batteries that started at 1550mAh in capacity, all the way to 2700mAh today featuring low-self discharge characteristics.  Today, Powerex batteries offer some of the highest capacity, best performing, consumer rechargeable batteries in the market today. 

26 years later, Maha Energy has stayed true to its values by providing products that outperform the competition and customer service that is second to none.
