What sort of battery charger and how to charge
Since the covid lockdowns the stop start has never recovered and still not working even though the cars starting to get some more use.
mid like to get a suitable battery charger and give it a good charge to see if it will recover.
what chargers do people recommend? And is there anything special I need to do to charge it or is it just a matter of connecting to the terminals under the bonnet?

from what i hear ; CTEK — Maximizing Battery Performance is very good
most of their models have a "restoration " function, which you might need

To me a battery charger is like gas: they are all about the same.
Just my $.02.

I bought a CTEK 40-206 MXS 5.0 Fully Automatic 4.3 amp Battery Charger and Maintainer 12V from Amazon: About $90 plus tax, free shipping. Works great.

FWIW: I have a 25 year old Sears battery charger with 10 and 2 Amp settings; In the spring and the fall, every six months, on the 10 amp setting I attach the charger to my battery overnight. The next day the charger indicates a full charge on the battery.

I suppose there's newer no name chargers out there that have better displays and a few more functions.
Here's a 10 amp one that's ranked #10 on Amazon's list of battery chargers and about $26.75.

The idea is never to let your battery go totally dead, it will lower the battery’s capacity. CTEK is rebrand as Porsche charger, battery tender and schumacher are also very good brands.

couple tips
We all get lazy and simply hook-up the charger without disconnecting the battery, right?
That's usually ok but note you don't want to use the "Restore Mode" or "AGM Mode" with battery in circuit.
These 2 modes involve higher voltages not so compatible with pricey electronics. Besides RTFM says to always disconnect batt!

Having a charged up battery keeps the electric load down during start and subsequent charging. The engine runs with less hick-ups when the voltage is well above 13Volts.

On modern Mercs as most would know, if you disconnect your battery completely you loose ALL the cars settings…all of them. So do you lads run some sort of battery saver to the pos terminal whist you charge your battery?

lost in translation ...
Nevermind, you can use a simple 9V battery maintainer to tame your fears.
Rebooting modern MB computers is truly one of the best temporary medicine against "sleepless SAM" draining system AGM - Zero side effects on settings, roof, windows...

Costco is your friend. They sell one for $20 less than regular retail. CTEK is the historical choice but I had one fail and it cost me a battery. I have one of the cars in storage year around.
