An article in the Beeb news prompted me to post this warning about the risks of buying electrical equipment on-line from the likes of eBay/Amazon and others. The article was about a photographery who lost his home in a fire for which the suspected, but not proved, cause was a faulty battery charger. Similar stories abound about laptop battery replacements and chargers.
I have personal experience of this but with no bad consequences. A few years back I flew RC Helicopters and Planes and needed a new Lithium battery charger. Having investigated the various makes I bought one from eBay. A known type in the RC community. Several minutes after using it for the first time, the high power Lithium cell started to swell up and then vented gas. This is why I never leave batteries on charge unattended and for Lithium cells like those, I have a fire-proof case which should limit the damage for a while.
When I investigated I found that the charger was continuously trying to charge the battery rather than shut down. Further investigation online revealed that there were a number of fakes going around - looking just like the real thing. I returned the unit, got a refund and filed a complaint and bought a different make from a model shop.
And a number of years back I bought a hot air gun / paint stripper from Argos. A make I hadn't heard of before but cheap. After few minutes use it flames shot out the front. I returned it to Argos and got a replacement - this did the same. Returned that and got a more expensive Bosch unit which is still going strong.
So, at this time of year when battery operated devices may be given/recieved as presents beware of charging batteries and what you buy on line.
