Current battery is a MOLL, EFB type. Haven't had it tested as it's showing no signs of degrading performance wise besides the occasional warning message. Car gets light use only with occasional decent run out, owner is my Mum who is in her 70s. I'd expect the battery to suffer during the winter months but it still sounds very strong to me. Battery was charged a few weeks ago via my Optimate. I've no concerns over the charging voltage. I'd have to check re switch, but have disabled it in the control panel previously, but does this still leave the charging system active? Just checked the replacement Lucas battery, it states AGM, so not sure if that's compatible? Cheers

Hi, first post, go easy. Been googling battery replacement for my Mum's 2016 Fabia, which has led me here. The car has occasional charging warnings flagging up, so I purchased a new battery to fit, which is still sitting in the garage as I may not actually need it after reading some of the content re the st/st system flagging up charging warnings. It shows no other signs of a lay battery, charging voltage around 13.8-14.0 at idle. So, the thing to do would seem to be to disconnect the st/st system? Can I then fit a bog standard battery rather than the £100+ item sitting in the garage? Will this lead to any other charging issues/warnings? I despise st/st systems personally, and have it disabled on all my other vehicles. Thanks in advance 🙂
