Hi Rahimeakyuz, You can try looking in your HP computer's manual(s) for the information about which batteries go with you computer. You didn't say anything at all about what kind of notebook you have - batteries and chargers do vary by age of the (computer) equipment and the type of notebook. • Go to the top of this Forum page - to • Open the HP web page for your Product / Model • Look under Manuals The manual you seek might be named 'Service and Maintenance' (or similar). There are usually a number of chargers that can be used with any notebook - it depends on the size of the battery you are trying to charge. Assuming support for the following batteries: ● 9-cell, 3.00-Ah (100-Wh) Li-ion battery ● 6-cell, 2.80-Ah (62-Wh) Li-ion battery ● 6-cell, 2.55-Ah (55-Wh) Li-ion battery One would not want to charge the 9-cell battery with the smaller 62 watt travel charger.
