Saw this on price hipster. By far the cheapest price. Plenty of stock around.
Good to keep your car batteries in top shape. They tend to last a lot longer if you charge them every now and then. I charge mine every couple of months or so.
The lowest price before this was $88.90
It will charge large deep cycle batteries but will take a long time.
Also note that this can charge batteries that have dropped down as low as 3v
I bought the aldi auto xs 3.8A charger which does car amd bike and also 6V. Currently goes for 29 but you can find it on clearance for potentially 20.
