And we 'd like to share a trick from quora.com, that could shed some light on many issues:

Why is my laptop battery not charging to 100%? How do I overcome this problem?

Soumya Sambit Rath, Electronics Student and Amateur Developer replied: 

I got your Problem

You must be experiencing kind of“97% remaining and not charging”.

This is a special feature in the modern laptops to protect the battery from overcharging and hence increase the life of the battery.

In most of the laptops, the Charging light on the Laptop turns GREEN from RED when the battery is charged 95%. When this GREEN light has come, just shutdown and keep the laptop connected to the charger. Wait for a couple of minutes and then again switch it ON.

You can verify, now it will surely show 100% remaining

This works because it is the system software that stops charging the battery. Once it shuts down, there is no software to monitor such things and hence battery gets charged to FULL

This trick worked with My ASUS X205TA.

Factors Affecting Battery Life

As batteries age they gradually lose their capacity as their function is performed. The constant charge and discharge eventually leads to failure. Components corrode over time, electrical shorts occur and vibration causes damage; all eventually causing failure. Overcharging and undercharging of a battery will also have a bearing on battery life.
Battery Inspection

Check electrolyte level - fluid below the tops of the separators indicates overcharging or poor maintenance. Overcharge condition may be due to incorrect voltage setting, low voltage caused by heat or internal defects, or old age deterioration.

Is there electrolyte on the top of the battery? This can indicate overcharging or overfilling.

Is the battery loose in the carrier? This can cause failure from vibration.

Does the battery have signs of damage or mistreatment? This can also cause failure.
Discharged (flat) Batteries

A flat battery should be checked with a hydrometer. A low Specific Gravity reading of 1.220 or less in all cells indicates a discharged battery and it must be charged before further examination and testing can occur. The discharged condition may be due to a problem in the electrical system (slipping alternator belt, faulty regulator or alternator, high resistance due to corrosion). Internal shorts may also be due to manufacturing defects or shorts through the ageing process or vibration damage.
Early Warning Signs

Batteries often fail when least expected. The usual warning is a slower than normal battery ability to crank the engine. Other less noticeable factors, such as changed driving patterns and colder/hotter weather will all have an effect on the life of a battery. Encourage your customers to ask for a ‘FREE Battery Test’. It’s good public relations and if the battery is near failure, it may avoid the inconvenience of a roadside breakdown.
