In ACF, the_field('battery'); outputs as follows :

Battery : Sony Rechargeable Ni-MH 2200 mAh battery

or

Battery : Energizer AA Rechargeable Batteries 2300 mAh NiMH 

How can i achieve this (showing only mAh details) :

Battery : 2200 mAh

or

Battery : 2300 mAh

You have to use a regex, in this case, to extract the needed value from a string:

$string = 'Energizer AA Rechargeable Batteries 2300 mAh NiMH';

preg_match('/([0-9]+\s*mah)/i', $string, $capacity );
    
if ( isset( $capacity[0] ) ) {
    printf('Battery: %s', $capacity[0] );
}

This regex /([0-9]+\s*mah)/i will look for any numbers followed by case insensitive mah combination.

You can test this regex online here https://regex101.com/r/KDdHbp/1/

Also, here is documentation on preg_match https://www.php.net/manual/en/function.preg-match.php
