My Peugeot 5008 66 plate has an AGM, and that’s it. One battery only. Due to complex charging usage and charging setup Mercs need 2.
Not necessarily! My Merc has a small AGM battery as part of the stop/start system, but that is only to keep the stuff like lights, aircon fan etc ticking over. When the car re-starts it is using the main (big) battery.. and that can be anything, Wet lead/acid for instance.
Just to confirm these are the EU plug versions, personally I've ordered a conversion plug which would appear to house the EU plug, thus converting it to a UK plug from CPC Farnell for approx £2 each. Therefore with the conversion plug inc delivery these are working out approx £13 each for me as I bought 4. If I'd have thought I'd have bought 5 or 6 & saved £4 on p&p.
I think the saving of approx £20 should cover the £2 cost of an adapter plug. My delivery of 4 of these chargers should be any moment now. 4 units for £44 delivered, if I'd have thought, with free shipping over £50 I'd have bought more.
Please bear in mind this is an EU plug 🙃
