Lidl and Aldi will do the job and are well priced.
As an aside, if you have ‘stop start’ on any of your cars and it stops working normally try putting the main car battery on ‘trickle’ for a day. Worked for me.
And another, it looks like the latest ND has ‘stop start’ or am I mistaken?
Just to confuse you even more! I use an Optimate 4 (from new - 3 Years) all the time due to low mileage journeys which are not lengthy enough for the alternator to replace the power used to start the car.
+1 for the Aldi as a conditioner charger. Only caveat is that if the battery is dead flat, you’ll need an old fashioned standard charger to bring the voltage up to a level where the Aldi smart charger can take over.
Everything all the previous poster have said is good information, but if you go looking for a ‘charger’ get out of your head the words ‘trickle charger’ and replace it with ‘CONDITIONING CHARGER’.
I have three of them and my car can sit for months at a time on one of them, in fact it’s now on it’s third week and if the weather doesn’t suit when i have chance to drive it, it will stay there until Spring.
Optimate works great. But it has a lead & you will trip over it, guaranteed. Usually whilst carrying something really valuable from the tinnie fridge in the garage to the house.!!
There’s an easy fix for this. Back in the UK I had my Optimate mounted in the garage roof. I fitted a lead [supplied with the charger] that went from the battery through past the spare wheel hole and into the cockpit behind the drivers seat, The charger lead was clipped up when out of use but only took a minute to connect up when I pulled into the garage. If you look carefully at the end of the red arrow you can see the lead hanging down
Don’t all chargers have leads? My Optimate “conditioning” charger and my two HD/trickle chargers each have a couple, one from the power-point to the charger, and another from the charger to the battery and I thought this was standard!
Seriously though. my Optimate is fitted high on the garage wall and it’s lead with accessory extension is secured to roof cross-beams so that it just drops down vertically to the car’s battery and plugs in to the optional permanent fitting on the battery.
