Lithium Ion Batteries

Recommended Posts

Bit of a heads up for those with these batteries and charging them.  Yesterday we had our second house fire in the last 12 months in a fairly small population where the cause has been these batteries on charge starting the fire.  In both instances the individuals were responsible, putting the batteries on charge after use, and not leaving them on indefinitely.  Both cases they were on charge in garages which lead to extensive damage - yesterday the house was a complete loss.

If you have these, 3 tips I'd recommend

1. Charge them in a steel box to minimise any spread when they do go, and better if they are away from any flammable items or liquids.  When they go, they go with a bang which seems to cause a quick spread

2. Install a smoke alarm near where they are being charged to give you the time to take action, remember to change the batteries in the alarm every 6 months

3. Check the battery regularly before putting on charge - any damage, place it in a steel box until you can get a professional to look at it.  Don't lose your house because you couldn't be bothered removing the battery to look at it.

i have no clue what sort of batteries you are talking about so what devices/tools or whatever were being charged?

Mostly in items that require charging.

The case yesterday was in remote control plane or something like that (higher end toy that cost a bit of dosh - were told it hadn't been on charge that long).  They also are used in garden implements - chainsaws, whipper snippers, lawn mowers etc that are replacing petrol models in most households. 

Most of them will say it on the battery

Jesus. We've got loads of those batteries. When we were renovating the house before we moved into it, we would leave them on charge overnight when we went home so they would be ready to go again in the morning. 

Thanks for the heads up. Will be very careful with those suckers in the future.

I always have one or two batteries on charge at any given time, might have to rethink that. 
Thanks for the heads up

Not trying to alarm anyone, most of them work fine, however the 3 points are what we were discussing on the way home as ways to prevent fires in our own homes.  2 house fires in 12 months across a population of approximately 10,000 by the same cause is a worry.  Put that out across a city of say 3 million and it equates to basically at least a house fire a day that could be prevented.

Most of the time they will be fine, but think regular checking for damage is essential.  I heard from a colleague today some of the new laptop style computers have them as well - first sign with them is the battery expands pushing the screen out slightly (Microsoft surfaces), if this happens get them looked at asap and don't charge them.  Smoke detectors are cheap
