Problem with Motorhome battery going flat

Pensionspender

For several years I have had a problem with my Autosleeper Talisman battery going flat when parked for less than 2 weeks. The AA have been called out on numerous occasions and they don't have any obvious reason for the discharge.

Does anyone have info on the best trickle chargers on the market so that I could plug it in when hooking up on site and also keep it charged up for the occasional outing through the winter.

Would be such a relief not to have that anxious feeling when I am leaving a site after a week or more in case my van doesn't start.

Sorry I am not very technical. i am a female driver approaching 74 and want an easy life!!!!
