Chinese Batteries, NOT a good idea

Beware Chinese batteries

Here is a tale of caution about buying cellphone and other portable appliance batteries from Chinese sources,  this example is of a built in Lithium/Polymer pack fitted to a satellite navigation device.

At first this battery would power the GPS unit for about 3 hours on a full charge, within one month it was incapable of sustaining power for more than 30 minutes, within one year, it would last barely 10 minutes and now at 18 months has insufficient capacity to retain the display alone for more than a few seconds.

The latest episode which is the most disturbing from a safety point of view is the potential explosion threat.  I heard a crack while driving that seemed to come from the dashboard,  suddenly the GPS unit flew out of the cradle and burst into two halves,  it had been split apart by the balooning of the battery pack, the 4 captive screws holding the back ripped out of their pillars and left the GPS in two parts lying on the dashboard.

Nasty happening while driving

This picture was taken back at home after I had cut the connecting leads to the battery,  prior to removing the offending pack to replace with a genuine cellphone spare.
