Most Macworld UK readers quickly checked their Apple notebook batteries when the company announced its battery recall - but some just can't be bothered to do so.

Apple recalled approximately 1.8 million iBook and PowerBook batteries at during the last week of August.

A recent survey here reveals that 54 per cent (549) of the 1,009 readers who voted have checked their machines, and found them to be OK.

An additional 27 per cent of readers who voted (273 people) checked their Macs and found that they were on the danger list.

Some readers are taking their time: 8 per cent (78) of then haven't checked their Macs yet, "but will soon", while an astonishing 109 readers (11 per cent) "can't be bothered" checking their machines.

iBook and PowerBook readers have been asked to check their batteries, as some of those now used are known to be potential fire risks.

The affected batteries were built in Sony plants in Japan, Taiwan and China, then sold by Apple between October 2003 and August 2006, both in new computers and as replacements.

Some of the batteries are prone to a fault, in which tiny metal shards left behind during manufacturing sometimes pierce the battery cell walls, causing a short circuit by touching an anode or cathode. And in a few extreme cases, setting the notebook ablaze.

Apple has confirmed nine cases in which its machines overheated as a result, causing minor burns in just two instances.

A complete list of affected batteries is available here.

Some readers welcomed the news. Writing on Macworld's forum, one wrote: "I haven't checked my battery yet, but I hope it is affected, as these days I am lucky to get over 30-minutes use out of it."

Others were a little concerned, one observed: "This matter makes me think on how many times I have flown working on my Mac at 30,000 feet. In the past my G4 PowerBook has grown warm, but not to the point of discomfort."

Readers also seem to have reached a consensus that it is taking Apple between 4-6 weeks to ship the new batteries to them. During the wait they are expected to cease using their existing battery. Many readers decline to do this, describing the risk as "minimal".
