Nokia cell phone batteries are made in family sets. A specific Nokia cell phone battery, identified with an alphanumeric notation will be used for different Nokia phones within a subset.
 For example, the Nokia phones E52, E55, E61i, E63, E71, E72, E73, E90, N97 and N810 tablet use the same battery since they belong to the same class and use similar components. This battery is BP-4L. Therefore, finding a replacement battery for one means finding for another. The capacities of these batteries are also the same for each set. Generally Nokia smartphones have batteries with capacities over 1000mAh while the feature phones have less than that. This is to meet the power draw from the faster processors and more powerful innards of those Nokia smartphones.

Generally, Nokia cell phone batteries are Lithium Ion batteries. The advantages of Lithium Ion batteries are what make them ideal for mobile devices such as Nokia cell phones. These advantages include the highest energy density per volume of all battery types; flexibility of design, size, shape and capacity; lack of the memory effect seen with Nickel-based batteries.
 Therefore, Nokia cell phone batteries do not need to be fully discharged before charging. They are also light, charge fast and come in small sizes.

To make your Nokia cell phone batteries last longer, do not overcharge them and remove them from phones when you won’t be using them for extended periods. New Nokia cell phone batteries do not necessarily have to be fully charged or discharged on first use. However, a few charging cycles is recommended before great performance can be expected. In addition, these batteries must be kept away from heat and moisture. When replacing the batteries, make sure they are aligned in the right directions in the phones’ battery compartments.
 Take care to clean the contacts too every now and then to remove dirt and prevent short circuiting.

Why do phone batteries die? After each charging cycle, batteries die a little. After awhile, these batteries will no longer be able to hold as much charge as they used to when new. The rate of discharge will also fall leading to phones dying out faster between recharges. Other signs of impending death to look out for include incorrect battery indicator readings and paradoxical indicators of fully charge within minutes of plugging in or emptying out within minutes of full charging.

When you need to replace your Nokia cell phone battery, first, remove the old battery and look for the identifying number on it.
You should see one like the BP-4L above. A battery with that number is the one you should shop for. Next, you go online or visit your local store looking for a replacement battery with that number. Make sure that the battery you buy as a replacement is branded Nokia and marked with the number from the old battery. In addition, both the old and new batteries must be the same size, shape and weight. That is the only way to be sure the new one will fit.

To replace your Nokia cell phone battery, pop out the phone’s back cover. Then prize out the old battery. When you put the new battery in its place, it should be a perfect fit. Finally, make sure you fully charge this replacement battery before you use it for the first time. It should give you a performance close to the one you got when you bought your Nokia phone for new.
