Hi group a VERY simple question for you ... (Hopefully)


I've got a Headlight which I use for fishing. It uses a
6Volt 4ah Sealed Lead Acid battery. My queation is
can replace the battery with a SLA of a 6v 4.2ah.

yes, definately.

My limited understanding of this is that the "ah" is the
amount of charge it holds and for how long...and maybe it
has little effect of compatability as long as its a 6VOLT battery.
Is this correct ?

yes, pretty much.

In rating batteries there's also cold cranking current,
but that won't be an issue in this application.
