Company History

Overlander's fine reputation for quality battery assembly began in 1975 when we started manufacturing packs for electric radio cars. Whilst battery technology and the range of cells and packs has moved on with time, our commitment to meet the needs of industry, commerce and UK Radio Control Modellers has remained constant.

We continue to grow our technical skills and knowledge which has helped us continue to develop and improve our own in-house manufacturing capabilities. We construct packs from both NiMh cells and Lithium Polymer at our factory in Forton, Lancashire. Our trained operatives always conform to our stringent best practices and the manufacturer's assembly recommendations.

Generally larger bulk quantities of batteries are assembled at our facilities in China. This invariably takes place to strict UK Overlander requirements and specifications and all suppliers are inspected thoroughly. We take pride in visiting our Chinese suppliers and partners on a regular basis which enables us to be confident that all goods produced for us match the quality of our "home grown" products. We are also keen to ensure that there are good working conditions and living standards for these distant workers.

Our mainstream business has grown over from serving the radio control modeller. However in recent years we have grown to manufacture and supply to other areas such as NHS Trusts, industry, aerospace, motorsport and university research departments.

Overlander are an official UK distributor for the market leading Eneloop brand of rechargeable batteries. We undertake both custom battery assembly with these and bulk sales. Later in 2014 by utilising our knowledge of batteries and longstanding relationships with suppliers, Overlander will be launching its own brand of Alkaline AA & AAA cells into the wider battery market. These cells have been carefully selected so that the wider public will soon be able experience the Overlander reputation for quality taken for granted by Radio Control enthusiasts for many years.


Overlander complies with all European requirements and has developed and implemented its own Quality Management Systems. In 2017 after a successful external audit from ISOQAR, Overlander was confirmed to have achieved the standard to be accredited as an ISO9001:2015 company. As part of this commitment we are always seeking ways and means to continuously improve our business.

Ethical, Environmental & Sustainability

We are committed to respecting and protecting the environment. We comply with all applicable legislation and are members of both the BatteryBack compliance recycling scheme and WeeeCare compliace. We shall always be looking for ways to improve our environmental performance, endeavour to prevent pollution and minimise the use of natural resources where possible.

At Overlander we recognise the importance of operating to a set of core values in the way that we carry out our business with our customers and supply chain. These core values seek to establish, protect and increase the trust and confidence of individuals and organisations with whom we interact, thereby enhancing our reputation and successful business dealings.


On 20th August 2013 Overlander were presented with their ISO9001 certificate by Roger Wood from ISOQAR.

ISO9001 is the internationally recognized standard for the quality management of businesses. Gaining this standard is a huge achievement for our company and something the team are very proud of.

This certification shows our commitment to quality, our customers and the willingness to work towards improving our efficiency.
