How to Recondition a Lithium-ion Polymer Battery

Updated February 21, 2017

Lithium-ion polymer batteries are rechargeable batteries that are found in common electronic products, such as laptops, cell phones, electric toothbrushes, electric razors and personal music players, just to name a few. Unlike traditional lithium-ion batteries, lithium-ion polymer batteries can be moulded into any shape and have the ability of fitting into small, odd-shaped places. Reconditioning a lithium-ion polymer battery helps keep the battery working properly and may help restore efficiency or loss of function. Reconditioning should be performed every three months.

Turn the electronic product off. Plug the power adaptor into the electronic product. Allow the power adaptor to completely charge the lithium-ion polymer battery.

Remove the power adaptor. Power the electronic product on by pressing the "Power" button.

Allow the battery to power the electronic item. This will help discharge or drain the battery. Continue allowing the battery to drain until it has been 50 to 60 per cent used. Most electronic products have an icon that indicates the remaining battery power. If the product does not have an icon, estimate based on the life of the battery.

Turn the electronic device off. Plug the power adaptor into the electronic product. Completely charge the battery. Repeat the process of draining and recharging a total of three times.


If you continuously drain a lithium-ion polymer battery below 50 per cent and then recharge it, reconditioning is not required. For example, cell phones are routinely drained and recharged by the user, so reconditioning would not be needed as it is commonly performed anyway. However, a camcorder may only be used on special occasions, so reconditioning the battery helps maintain its function.
