1. How long does a compaq presario cq56z-200-cto battery last? When should I consider replacing mine?All rechargeable batteries wear out with time and usage. As time and cumulative use increase, the performance will degrade. For the typical user, noticeable reduction in run time generally will be observed after 18 to 24 months. For a power user, reduction in run time generally may be experienced prior to 18 months. We recommend buying a new compaq presario cq56z-200-cto battery when the run time does not meet your needs.
2. How should I choose between two batteries with different Watt hours (Whr) available on one system?

For example, if you compare the same system, running the same applications, the 53Whr battery would provide approximately 65% more run time than the 32Whr battery.
