Don't waste your money on D cells rated less than 10,000mAh
on 8 September 2014
Prior to purchasing low mAh rated D batteries, type " "D" Battery Exposed" into a search engine and read. Unfortunately I did this research only after purchasing this product, where one of the batteries I received rattled and the power from it was intermittent. From reading the article I can only assume why a "D" battery would have a smaller object inside of it that moves and rattles when the battery is shaken. Keep in mind, that the postage cost to return the battery to the supplier is a minimum of £2.80, not far short of the cost of the battery itself. Royal Mail also has strict restrictions on sending batteries, especially faulty ones (check their Prohibited & Restricted Goods section on their website) and you will be asked by Royal Mail staff what you are sending, which can make returns a difficulty to say the least. My advice is spend the extra money and buy a full capacity D cell (i.e. around 10k mAh or more) where the whole of the D sized cell is electrolyte. The seller was not at fault here providing the product as described promptly and a replacement of the faulty cell, it was a manufacturing fault and a product designed in such a way that such a fault is more likely to occur. It is a shame the manufacturers of these products are not more transparent with the nature and design of these products so the consumer can make an informed decision when purchasing. I certainly would have made a different purchase, regardless of the additional cost. When these batteries are spent I'll also take them apart and post up images of what was rattling about inside.
