4 tips to spark longer life from your Li-ion batteries

Our technology largely revolves around using batteries. This applies to whether it’s the battery in our electric vehicle or our laptop or smartphone. We never seem to get enough battery life from them, so if you rely on Li-ion batteries you might want to check out these 4 tips to get longer life from your batteries.

1. Bear in mind that batteries only have a certain shelf life and they will degrade over time. All batteries will have a calendar life so it pays to check it on any packet that you have stored to find out how long they last. With this in mind when out shopping for batteries you should check the packets and purchase your batteries in much the same way as you would buy milk. Buy the freshest possible if you plan on keeping them on the shelf. Of course if you can get a discount on batteries as their shelf life is coming to an end this is all well and good, providing that you are going to use the batteries within the date.

2. Temperature plays a very important part on how long your batteries are going to last. The Li-ion batteries will be very happy at room temperature of around 20 centigrade to 25 centigrade. If the weather gets hotter than 25 centigrade it can break down a protective layer in the batteries and when this reconstitutes it will take away some of the energy from the battery. If the temperature is colder it causes the batteries chemical reactions to slow down and this can cause an issue that can be likened to cars at roadworks in rush hour, they all try to get through. Out of the two a colder temperature is the least harmful.

3. Do you know when to charge batteries and how long the battery should be on charge? In the older batteries that could be recharged charging and discharging of batteries decreased the amount of energy capacity and this was due to nickel cadmium. However with Li-ion batteries this isn’t the case. These batteries tend to degrade the most when they are fully charged. This means that if you leave them for weeks and don’t use the device they are in, ideally they should be left with a low charge of around 20%. If you are charging and discharging a lot then you may want to keep them at around 50%. When using batteries and charging them just a little at a time, you should do it about 45% to 55% and not 90% to 100%.

4. You would not heat and cool at the same time would you? Well this is exactly what you are doing if you make the batteries give high amounts of power output or charge fast. The protective layer that is on the batteries breaks and then has to rebuild and this is the same effect as a traffic jam. In short you should never put a lot of strain on the battery at any one time.
