Default 12V battery charger from Screwfix - specifications?

It seems to be impossible to find a detailed specification for
these chargers. I found a document relating to the larger
6/12V switchable 8 & 12A versions but these are only operating
instructions. The nearest irt comes to a specification is to
state the maximum charge rates but, at least, is does say that
the 12A version is suitable bir batteries up to 160 Ah and up
to 112 Ah the 8A version so, pro rata, the figure for the 6A
one underdiscussion here is likekly to be in the region 0f 75
- 80 Ah.



I'll bet those charge figures are a peak output plucked from the air.

Makes you wonder how the car alternator can re-charge the battery so
quickly if 6 amps is a safe amount into an 80 amp.hr battery which is
towards the large size for most cars.

I have a Halfords charger - a few years old but claims to be automatic. On
the front says 11 amps. It takes longer to charge my car battery than the
14 quid Lidl one which only claims about 4 amps.
