Why disconnect it.... Buy a "Smart Charger" So long as you connect the negative lead (black) to a suitable point on the vehicles body work and the positive (red) lead to the battery + then there is no need to disconnect your battery. (Remember to leave the bonnet slightly open to allow for air circulation)
A decent "Smart Charger" will let you know when your battery is fully charged.
Once charged (after a min of three dormant hours) it would a good idea to reset the BMS (battery monitor system). See utube for how.

Put battery on charge. Thanks for advice. And know howto reset BMS. Noticed the battery is a Rombat. From another post should I replace this brand?
Only had the car a week so this battery could be ok, it’s a 3 year old car and got it from a ford dealership.

Some have changed the battery to Varta and say that cured the deep sleep problem. Personally, on my last Puma the dealer did a software update to something and it cured the deep sleep without changing the battery.
Touch wood it hasn't raised it's ugly head in the new one (yet) and there are not so many on here reporting it as a problem now. If you look at this thread viewtopic.php?t=713&start=300 you will get some idea of the problems the older ones seemed to have with Deep Sleep.
Charging your battery should hold the problem off though.

Purchased a used Focus Estate recently and it was going into deep sleep for first few days after sitting on the dealership forecourt for a short time.

All fine now after using it in Sport mode for a bit, with the more aggressive regeneration.

I hope you have sorted your problem. My own experience over the years has been that once a battery is giving trouble, especially in the winter, the best course is to replace the battery immediately. It can be a false economy to keep recharging. If you get stuck part way through a journey, you will curse your luck and wish you had taken the bull by the horns and paid for a new one. I am assuming that the battery you have is no good. If it has a green tell tale light which is no longer visible, replace it. I am assuming that the charging system is working properly, but replacing the battery as a first step is often cheaper than getting the system checked by the dealer.
