dryfit A 200 / A 300
Universal in use, tried and tested over the years.

The batteries in the Sonnenschein dryfit A 200 / A 300 range are compact, versatile and can be used in a wide variety of applications. Both ranges consist of sealed, rechargeable lead-acid batteries in which the normally liquid electrolyte is held retained in gel form. This means that dryfit batteries are completely maintenance-free and are particularly economical in use. Savings of up to 30% are achieved in comparison to conventional batteries using liquid electrolyte due to the elimination of maintenance costs. Elaborate, separate battery charging rooms with their associated equipment are no longer needed. In fact dryfit A 200 / A 300 batteries can even be charged in living accommodation. Power, economy and easy handling are not the only salient features, since the batteries are extremely low gassing and very rugged with a long service life. Short recharging times round off their low self-discharge, they are ready for operation without further recharging even after lengthy storage periods of up to two years.

dryfit is an extremely environmentally friendly battery system. Right at the start of the battery development stage consideration is given to the environment with the choice of environmentally compatible alloys and other materials. Production takes place with modern facilities and environment protection engineering. Sonnenschein guarantees acceptance and proper disposal at the end of the battery's service life.

Lead and plastics are recycled and fed back into the production process.

dryfit A 200 / A 300 batteries fulfil the highest demands with regard to service life in continuous battery power supply mode and for endurance in the cyclic mode (A 200). They can be employed in a multitude of applications:

- Telecoms
- UPS systems
- Alarm signalling
- Medical (infusion devices for intensive wards and for drip-feeding premature babies)
- Remote control engineering
- Model boats, aircraft, etc.

dryfit A 200 batteries are also especially suitable for use in electrically operated wheel-chairs, golf-caddies and other cyclic applications.

Sonnenschein dryfit A 200 / A 300 batteries are available in a finely graduated power range with capacities ranging from 1-200 Ah.

dryfit A 500
When security of the power supply is the primary factor.

Today, electrical power is indispensable and we daily depend on a continuous supply in all aspects of our life. An uninterruptible power supply is particularly important where life and health depend on electrically powered equipment. We only have to think of emergency lighting, escape route indicators and smoke detectors in, for example, hotels, banks, leisure centres, cultural facilities, hospitals and underground car parks. But also telephone systems for maintaining crucial communications, technical equipment for guaranteeing clinical supplies or emergency telephones on motorways.

Furthermore a continuous power supply is needed for the operation of alarm signalling systems for protecting objects. Irrespective of whether this involves the supervision of entry areas, bank premises, cash dispensers, doors, windows or value exhibits in museums - everything depends on a continuous power supply. But it should not be forgotten that a continual power supply is also indispensable where a power failure may cause severe commercial losses, for example in refrigerated warehouses, transmitter systems or electrical plant.

In order to ensure that the power supply is guaranteed at all times, essential facilities are backed up with high performances battery systems. Sudden breaks in the power supply are then no longer a problem. If the power suddenly fails, battery systems take over the emergency supply of power or start up diesel-powered generators.

dryfit traction Block
Absolutely maintenance-free traction batteries for small electric vehicles

The dryfit traction Block is made up of grid plates of a special antimony-free special alloy and separated using high-quality, microporous and specially insulated plastic separators.

The plates are arranged by polarity and connected to one another by connecting straps.

The individual plates are - depending on the required voltage - connected by intercell connectors inside the monoblock housing. The plates are installed in resistant and easily transported monoblock containers made of polypropylene.

Technical Advantages

- maintenance-free - for the entire service life, i.e. at least 700 cycles according to DIN
- non-sensitive - to occasional deep discharges
- economical - cost saving up to 70% over the service life; also: no maintenance activity and no material costs for clear water
- reliable and long-lived - because maintenance errors are impossible and electrolyte contamination cannot occur
- extremely low gassing
- no acid leakage - so no corrosion at the connectors or terminal connections and on vehicles
- no readjustment of charging units necessary
- full charge automatically assured even after years of operation
- no restrictions on how the battery is arranged in the vehicle, since maintenance is not required
- interim charges possible at any time
- very low self-discharge (only 35% of the rated capacity after 12 months in storage at 20C), so Sonnenschein dryfit traction batteries can be put into service at once even after lengthy transportation and storage time
- easy transportation: Sonnenschein dryfit traction batteries can be transported ready for use even when filled and charged, by sea or air freight
- extremely high vibration resistance - gelled electrolyte means mechanical solidification of active material particles

dryfit sportline
The superior battery for marine and leisure applications
