Sonnenshein Blocs

sonnenschein-batteriesSonnenschein are a respected brand providing batteries that are compact and versatile enough to be used in a wide range of applications. The dry fit technology in Sonnenschein blocs allows for a closed system battery whereby the electrolyte is fixed in a gel. The most significant benefit of this is that these batteries need absolutely no maintenance at all throughout their entire serviceable life. Sonnenschein batteries also have the added advantage of delivering the highest reliability even when used in the most extreme operating conditions.

Sonnenschein blocs are suitable for a variety of deep cycle applications and are particularly popular for mobility, marine and leisure, solar and military use.

Benefits of Sonnenschein Blocs

  • Completely maintenance free - no topping up is required for the entire service life of the battery
  • Extremely high intrinsic safety as the closed system prevents any acid leaks
  • Robust and reliable in even harsh uncontrolled environments
  • Low self-discharge rate
  • Extremely low gassing due to internal gas recombination
  • Trouble-free transportation of operational cells with no restrictions for air, rail or sea transportation
  • Non-hazardous, clean and environmentally friendly
  • Completely recyclable

Sonnenschein Blocs for Marine, Leisure and Mobility Applications

deep-cycle-gel-batterySonnenschein’s batteries for the leisure and mobility market are widely used in electric boats, golf cards, wheelchairs and mobility scooters. The reliability and long life of these batteries allow them to provide high performance without compromise.

As well as being completely maintenance free, due to the closed system the Sonnenschein range will not leak acid and so can be used horizontally as well as vertically. Amongst other advantages this provides users with the freedom to travel by air with their mobility equipment.

Sonnenschein Blocs for Industrial, Commercial and Military Applications

As Sonnenschein batteries are robust and reliable enough to be used in even harsh uncontrolled environments, they are particularly suitable for industrial, commercial and military applications where low maintenance and high reliability are of paramount importance.

The dry fit technology used in these batteries guarantees that these batteries are completely maintenance free, easy to handle, environmentally friendly and offer impressive cost efficiency (the A600 series offers around 30% less overhead cost when compared with traditional batteries).

The Sonnenschein range of solar batteries have been designed for medium to large solar powered application. Because they are environmentally friendly, recyclable and can be stored for long periods without the need for recharging they are ideally suited to use in solar and wind power stations and power distribution companies. And as well as allowing for an uninterrupted power supply for telecommunications applications, Sonnenschein blocs are also ideal for emergency lighting, security, railways, utility and safety equipment power supplies.

Sonnenschein Battery Technology


braibar-engine-2v-cellsEvery part of a Sonnenschein battery is developed for optimum performance and highest reliability. Design features include:

Positive plates - these are robust tubular plates which consist of a lead calcium alloy which is optimised for high corrosion resistance.

Negative plates - these feature grid plate construction consisting of lead calcium alloy.

Separator - used to separate the positive and negative plates, it is microporous, robust and optimised for low internal resistance.

Poles - these feature a screw connection for easy and safe assembly and maintenance free connection with superior conductivity.

Valves - these release gas in case of excess pressure and protect the cell against the atmosphere.
