FAQs About Notebook Batteries
We expect notebook batteries to last a lifetime due to them being rechargeable. The fact is all notebook batteries will need to be replaced at some point. Proper care and knowing what affects the life of your battery can help you to get more from your purchase.
Q: When should I consider replacing my notebook batteries?
A: All rechargeable batteries degrade over time. Usually the first sign of replacement is a change in performance. The battery replacement timeframes are 18 months – 3 years.
Q: How long should I be able to use a fully charged battery?
A: Several factors affect the length of time your battery will operate before it needs to be recharged. A few contributing factors are brightness of screen, number of applications running including those running in the background, types of applications running, and system configuration.
Q: Will discharging and then recharging make a notebook battery last longer?
A: No in fact it is recommended that you only discharge your battery once a month. If you do so more than that, you may damage your battery. If there is an emergency or if your notebook needs to be serviced, discharging multiple times is acceptable.
Q: Can I use a different brand battery than the manufacturer brand that came with my notebook?
A: Yes and most generic batteries are just as good as name brand. Keep in mind though if your notebook is still under a warranty, you may default if you use a different battery?

A: The battery contacts can be cleaned with rubbing alcohol or an eraser. This should be done every so often. You may opt to alternate by using rubbing alcohol one time and the next time use an eraser and so on.
Q: How do I determine what battery will give me the longest life before needing to be recharged?
A: As a rule of thumb, the lighter the weight and lower the cost, the lower the capacity and run time will be. Higher cost and heavier weight equate to higher capacity and longer run time.
Q: How do I dispose of my old laptop battery?
