Actually, the opposite is true. Exposing your battery to high temperatures is a much more likely way to end up reducing its overall life. But why do batteries hate the heat so much? The reason has to do with the liquid electrolytes that fill the gaps between the lithium cobalt oxide and graphite layers remember them?

At high temperatures, these liquid electrolytes start to break down, causing the battery to degrade over the course of just a few hundred charge cycles. This is a major issue for electric vehicle batteries, which often spend much of their day sitting out in bright sunlight. Strangely enough, batteries are under the most strain when they're fully charged or completely empty. The real sweet spot for a battery is 50 per cent charge as that means that half of its moveable lithium ions are in the lithium cobalt oxide layer and the other half are in the graphite layer.

This equilibrium puts the least amount of strain on the battery, and extends the number of charge cycles it can withstand before degrading. So really, if you were super-keen on keeping your battery living as long as possible, you should keep its charge between 20 and 80 per cent. This means that it spends as little time as possible with lots of lithium ions crammed into either layer, a situation which causes the layers to expand, putting physical strain on them.

Maybe not, then. What do you do with your used or dead batteries? Store them in a non-metal container in a cool dry place until you can properly dispose of them. The Environmental Protection Agency EPA recommends taping the terminals of used batteries with electrical tape or by placing each battery in separate plastic bags. Terminals that rub against each other could cause a spark. Never put loose batteries in a drawer or area where they may come into contact with metal items such paper clips or steel wool.

They will go straight to the landfill. We recommend that you remove the rechargeable batteries before disposing of an electronic device; most electronics recyclers do not recycle batteries separately. To make sure they are recycled properly, make sure they are going to a battery recycler for processing. Call2Recycle makes rechargeable battery recycling easy.

In the case of lead acid and sealed lead acid batteries during discharge, sulfates in the electrolyte move to the plates and recharging pushes these sulfates off the plates and back into the electrolyte. In lithium-ion batteries ions move from the negative electrode plate to the positive electrode while recharging pushes the ions back to the negative electrode.

Unfortunately, the reversing process involved charging a battery does not work perfectly. With lead acid batteries some of the sulfates on the plates during discharge crystallize and cannot then move back into the electrolyte during charging. In Lithium-ion batteries a film builds up on both electrodes with each charge and discharge cycle which blocks the movement of ions. As the electrodes become ever more covered in these materials their ability to be part of the chemical reaction needed to make the battery work degrades.

They discharge faster and cannot recharge to the same level that they were able to when new. Eventually they are unable to charge to the point needed to power the appliance they are designed for. This rate of build up varies by battery type.
