Ring RSC504 4A Weatherproof Automatic Smart Charger 12V
Only suitable up to 1800CC
I am sure this product will be okay . Be aware that this size is only suitable for cars up to 1800CC. I have not opened this so have to go back and upgrade. there was nothing on the Web to say this would be a problem, as it says suitable for all battery types. Just a waste of my time. hopefully the bigger model will do the job.

Ideal trickle charger
Perfect if you only use your car/mower infrequently. It charges at 4 amps and automatically reverts to 2 amps then shuts down when battery is fully charged. Charging starts automatically again as battery slowly discharges.
Good quality and a nice compact size that will fit under bonnet with it closed.
My only complaint is that the mains supply lead is too short and this model has just the basic features. No led voltage indicator and no battery test/recover function. For those you will need the 8 amp version at considerably more expense. This is not made clear on either Screwfix website or Ring's website.

Did the job!
Purchased this charger as needed something to sit under bonnet of a car at a motorshow event and keep it charged up while it sat all day with touchscreen display and LED daytime running lights all activated. Did the job I needed it to do. The next model up which has LED display, charges at upto 8A and has 7 different charge modes is probably better value for money, but the slightly smaller size of this model suited my requirements better on this occasion.
