If you are working with the cord length still attached to the power adapter (transformer), make sure you slide the shell for the new connector onto the cord and faced the right way before you solder on the connector. Otherwise, you'll be faced with doing it all over or just taping the heck out of the connector. The length of the barrel connector that fits into the laptop body is somewhat flexible, too long can work, to short and you may be able to back-off a little on the connector shell.

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.
