I have bought these previously and they imo are comparable to brands costing much more and are beyond comparison when at this price. Beware buying cheap batteries that aren't alkaline unless for use in low power items such as clocks etc.. I know because you can buy batteries in pound shop etc.. but they are inferior du to being zinc carbon.

Beware buying ANY disposables as they are a waste of money as well as wasting the planet too!

The arguments have been made many, many times, yet still people see these things as an option :-(

Get your facts right if recycled like other potential wastes such as plastics, they are not wasting the planet.

Battery reprocessing

Batteries contain a range of metals which can be reused as a secondary raw material. There are well-established methods for the recycling of most batteries containing lead, nickel-cadmium, nickel hydride and mercury. For some, such as newer nickel-hydride and lithium systems, recycling is still in the early stages.

There are a number of different recycling processes for batteries, which are aimed at recovering a variety of materials:

Lead can be recovered by either separating the different materials that make up the battery (lead, plastics, acid, etc.) prior to metallurgical processing. Alternatively, batteries can be processed as a whole through heat treatment in a particular type of furnace with metals being recovered at the end of his process.

NiCd batteries can be reprocessed through a similar thermal technique, which recovers cadmium and iron-nickel for steel production.

Batteries containing mercury (button cells) are most commonly processed using a vacuum-thermal treatment, in which the mercury vaporises. It condenses and eventually solidifies when temperatures are reduced and can then be reintroduced into the material cycle.
NiMH batteries are reprocessed by mechanically separating the individual materials (plastic, hydrogen and nickel) within a vacuum chamber to prevent the escape of hydrogen. The output of this process is a product with high nickel content which can be used in the manufacture of stainless steel.

Li-Ion batteries are currently reprocessed through pyrolysis (heat treatment) with the primary recovery the metal content.

Zinc-carbon/air and alkaline-manganese batteries can be reprocessed using a number of different methods, which include smelting and other thermal-metallurgical processes to recover the metal content (particularly zinc).
