Well, l added 2 bottles of INOX battery re-conditioner to the Range Rover dead battery, left it on charge for 24 hours until the lights on the charger were showing fully charged and put it back in the Rangie and she kicked over first time.

Will see how long it lasts if still going in 6 moths time might add another bottle of INOX

INOX cost $9.95 for 95 ml bottle

Apparently adding it before battery is dead is advisable
