Lead-Acid

Lead Acid batteries as a chemistry have been around for over 150 years. The “sealed” aspect arrived on the market in 1972 with the Cyclon battery. Since then the number of sealed, or more correctly, Valve Regulated Lead Acid batteries on the market has burgeoned. This does not, however, mean they are all the same!

There are a number of different types of Valve Regulated Lead Acid batteries, their quality and features can vary widely from manufacturer to manufacturer and it is worth investigating which is the most suitable for your application.

As an independent battery distributor DMS technologies can work with you to balance quality and cost to ensure the right battery is chosen for your application. 

Chemistry

Lithium

While the term “Lithium” is generic, many of the advantages and disadvantages of these chemistries are consistent when compared to Valve Regulated Lead Acid (VRLA) and NiMH alternatives. We have tried to illustrate some of the similar advantages and disadvantages below, although please be aware that the extent of either can vary depending on the specific chemistry.

DMS technologies is experienced in building Lithium batteries and battery packs for a wide range of applications. Our experience is with a wide range of chemistries from various manufacturers and we build both primary and rechargeable products. At our facility in Hampshire we are set up to assemble Lithium cells into ABS cases providing a drop in replacement to lead acid products. These battery blocks can contain the cell management and protection, maximising the advantages of Lithium while minimising any changes to the existing solution. 

Chemistry

Nickel Metal Hydride

Rechargeable NiMH batteries have rapidly become more advanced and recent developments have further improved their self-discharge characteristics and brought higher capacities to the marketplace. The NiMH battery offers design versatility; they are ideal for custom-build designs and standard applications requiring high performance. Typically they offer a weight saving over AGM or Gel products at a lower cost than new lithium technologies.

Chemistry

Nickel Cadmium

Nickel Cadmium as a battery chemistry has been reducing in use in recent years as the superior capacity of NiMH batteries and lower cost has supplanted their use. The European Union also has certain regulations on the usage of NiCd further reducing their possible applications.

DMS technologies supplies a wide range of NiCd batteries from different manufacturers for a range of applications. We work with this chemistry in permitted markets, such as defence, medical and emergency lighting, so if you have a requirement or are looking at a replacement solution please do not hesitate to contact us
