Hi @richardblah

If the motherboard in your Acer Aspire 5551 is an LA-591 the cmos battery is soldered onto the motherboard.

Here's an image showing where it is located.

Usually the battery model number is stamped on the battery. Search online using that number to find suppliers that suit you best.

Make sure that you reinstall the replacement the correct way, polarity wise, so as to prevent damage to the battery from occurring.
