Nissen Premium 800 6 V Battery IEC 4R25, Zinc-Carbon 7-9 Ah, Mercury and Cadmium Free - for Lamps, Lanterns and 12 V Battery Boxes

The Nissen Premium 800 is a 6 V dry block battery in the standard IEC 4R25 size. This German manufacturer of road safety equipment uses it in its own warning lamps, rapid marking lamps and guide light systems, where a light has to run for a long time without mains power. Capacity is 7 to 9 Ah, depending on load and temperature. The battery uses zinc-carbon chemistry, contains no mercury and no cadmium, and the manufacturer points out its high resistance to cold. When camping, it powers a lantern or lamp made for a 4R25 battery, and two of them in a battery box with a 12 V socket run small 12 V devices without the vehicle battery and without a mains hook-up.

A 6 V block battery in 4R25 size

• model Nissen Premium 800, dry block battery
• designation IEC 4R25
• voltage 6 V
• capacity 7-9 Ah, depending on load and temperature
• zinc-carbon chemistry, 0% mercury and 0% cadmium
• high cold resistance according to the manufacturer
• size 67 x 67 x 98 mm, weight 0.45 kg
• single-use battery, not rechargeable

The label has a small table where you write the start and end date of use. This way you always know how long the battery has been running in the lamp or in the box.

What IEC 4R25 means

The 4R25 symbol comes from the international IEC standard for batteries. The number 4 stands for four cells connected in series in one housing, the letter R for round cells and 25 for their size. Four cells of 1.5 V each give 6 V in total. 4R25 batteries have a rectangular housing with two contacts on the top, so they fit devices with a compartment made for exactly this size: warning lamps, hand lanterns, camping lamps and work lights. Before you buy, check the manual of your device to see whether it needs a 6 V battery in 4R25 size.

Where the Nissen Premium 800 battery works well

The manufacturer designed this battery for its own warning lamps and guide light systems that run for many days without a break on roads and construction sites. The same qualities are useful when you travel with a motorhome or caravan. You can put the battery into a lantern or lamp with a 4R25 compartment, into a work light you leave in the awning, or into a warning lamp that you set up next to your vehicle after a breakdown. The battery needs no charging before use, so you can keep it as a spare and use it when you need it.

Two batteries in a box with a 12 V socket

A single 4R25 battery gives 6 V. A box for two batteries connects them in series, so you get 12 V at the 12 V socket. Capacity does not add up in a series connection and stays at 7 to 9 Ah. Such a set powers small devices with a 12 V plug, for example a lamp, a small submersible pump or a portable shower, away from the vehicle battery and from a 230 V hook-up. Always put two new batteries of the same type into the box and replace them together.

Capacity and operating conditions

The manufacturer specifies a capacity of 7 to 9 Ah. Actual running time depends on the current drawn and the ambient temperature. Zinc-carbon batteries work best at low and moderate loads, for example in LED lamps, flashing lamps and devices that run with breaks. At high continuous current the available capacity drops. Nissen points out the high cold resistance of the battery, which makes it a good choice in autumn and winter for lamps placed outdoors.

Storage and safe use

• this is a single-use battery, never try to recharge it
• store it in a dry and cool place, away from heat sources
• do not short the contacts with metal objects, for example in a toolbox
• remove a used battery from a device you will not use for a while
• in a 12 V box, do not mix a new battery with a used one or batteries of different types
• keep batteries out of the reach of children

Disposal of used batteries

Do not throw a used battery into household waste. Take it to a battery collection point, to a shop that collects batteries or to a municipal recycling centre. The battery contains no mercury and no cadmium, but it contains other materials that need to be recycled.

Good to know

• the package contains one battery
• the label shows the manufacturer number 155051, the IEC 4R25 designation and a table for operating dates
• the battery matches the 4R25 size used by many warning lamps and lanterns
• to power 12 V devices you need two batteries and a box with a 12 V socket

Two contacts on the top

Both contacts, plus and minus, are on the top of the battery. When you insert it into a lamp or box, check the polarity marks in the compartment. Make sure the contacts are pressed firmly against the terminals of the device.

Matching parts

• Battery box for two 4R25 batteries with 12 V socket - power for small 12 V devices from two batteries
