How it compares in Household Batteries, Chargers & Accessori
Across the 46 rated household batteries, chargers & accessori products we track, the typical score is 4.6 out of 5. This one sits at 4.6, which is in the bottom quarter of the category. That does not make it a bad buy, but there are better-rated alternatives on the same shelf, so it needs another reason to earn your money.
It carries 240,311 ratings against a category median of 17,635. A rating from a large base is harder to distort and tends to hold up over time, so a high score here means more than the same score on a new listing.
On price it sits in the middle third of a category running from £2.99 to £19.99, where the midpoint is about £6.92. That is the part of the range where most sensible buys sit, neither cutting corners nor paying for the name.
