give you the correct Laptop Battery

& Model Before purchasing an AC Adapter Satellite A70 you need to make sure make the AC Adapter will give you the correct Laptop Battery voltage and suitable current output.

To find out the voltage & current, turn your laptop over and look for a label, sticker or writing which shows the voltage and current, it should look something like the examples below. The voltage figure will have a "V" after the number i.e 19V and the current will have a "A" or "mA". i.e 3.15A. You can also find these shown on your original AC adapter if you have it. The Voltage must be within 10% of your original AC IBM Laptop Battery Adapters Voltage. The Amps may be higher but they cannot by lower.

If you are purchasing a universal AC Adapter or Car Charger you will need to work out the Watts of your original AC Adapter and select the universal Laptop Battery AC Adapter or Car Charger with the same Watts or next highest Wattage. You can work out the Wattage by multiplying the Voltage by the Amps i.e 20V X 3A = 60 Watts. There is no 60 Watt AC Adapter so you will need to select the next step up which FRU 92P1137 is the 70 Watt AC Adapter.

PLEASE NOTE: If the wattage requirement for your laptop is lower than the 60W or 90W output of the adapter, it will not damage your laptop, your laptop will only take the amount of power it requires. I.E. If your laptop needs 45W, then either the 60W or 90W will work OK. If your laptop needs 80W then you will need the 90W one as the 75W one will not be powerful enough.
