Energizer leaking batteries - Hopefully in the future a thing of the past

I put some Energizer batteries into my sons toy car about 3 months ago, there is still charge and the toy was still working when I noticed a clear liquid coming from the battery compartment. Here are the pictures after opening the battery compartment.

As you can see 1 battery is clearly leaking, which I sure would be very harmful to my young son, or any child. I feel let down by this brand named company, and thought I was buying a safe quality product. Anyway I will not be buying these batteries again, and would advise not purchasing them until they sort out their safety problems.

Hopefully the future of batteries means that these sort of things never happens again, but I am not sure if this will be possible. It sounds like carbon nanotube batteries are the future, but they still contain acid, so how can they remove the risk? I am not sure, maybe the housing of the battery needs improving, also could improvements be made to the product that requires the batteries? I am not sure, but think it needs to be made a priority by the manufacturers to stop this sort of thing happening.

Nexus 4 battery problem

The other day my Google Nexus 4 phone had a battery charging problem. I put the phone on charge with 43% remaining and after a few hours maybe up to 5 the charge was only up to 45%. Taking it off charge and looking at the usage it dropped back down to 44% within a minute. I thought I was in trouble and there was a physical problem with the battery. The solution was to completely turn off the phone and switch it back on, then it started charging fine and I've had no problems since. The only thing I can think of that could have caused a problem is either the number of apps running or a specific app that causes a problem, will keep an eye on it.

The Nexus is not great when it comes to keeping its battery power and I have to charge mine on a daily basis. Here are some tips on improving the charge of the battery.

• Switch the NFC and Bluetooth off when you don't need it.
• Turn off App syncing when you don't need the App to be synced.
• I've chosen a dark background to try to reduce brightness.
• Apps that have the option to change the background colour I've set to black.
• Check the battery usage and see what areas could be improved.

Samsung NC10 Battery Problem Fixed

I have owned a Samsung NC10 netbook for the past 2 years, a couple of weeks ago I tried to use it and it was dead, I plug it into the power supply and left it to charge for a couple of hours. I then disconnected it from the mains and tried to switch it on, it tried to start up but after a couple of seconds went dead. I then connected it to the mains power supply again and it worked fine. The battery manager reported 0% charge, and on the front the green light was displayed, so I figured there was a problem with the battery.

The netbook was out of warranty, but I still tried calling Samsung customer support, they were very helpful and we tried a couple of things to fix the problem, but the conclusion was that I needed a new battery. From the link Samsung support gave me to a retail site a new battery would cost about £70 ($100).

I heard somewhere that putting the battery in the freezer might help, I was not sure whether I was getting this confused with rumours that this fixes damaged hard drives, but I thought I would give it a go. I put the battery in newspaper and in a plastic bag and left it in the freezer over night. The next day I took it out of the freezer let it stand for an hour, then tried it. Nothing happened and it did not work, so I thought that's it I need a new battery.

I left the battery on the side for a week, until the following weekend. I was about to look at purchasing a new battery when I thought I would just give it a go again. I started the netbook up without the battery plugged in and with it connected to the mains power supply, I then plugged in the battery and was surprised to see the red light on the front instead of the green, which indicated it was charging. I left it for a couple of hours and when I came back I could unplug the mains power supply and it worked!!!

I still think there is a problem because it seems to report 99% power now, but I can use my netbook without having to plug it into the mains power supply and this also saves me £70 for a new battery.

I cannot say whether putting it into the freezer was part of fixing this problem, or whether just unplugging the battery and leaving it for a week helped, but something weird happened that has fixed the problem.
