Solar Maintenance Chargers (Car Battery)
« on: August 08, 2018, 08:13:01 PM »
I've been trawling the 'net, a lot of the static seems to be from about 2015-2016 but I note many vendors have changed models or their function statements since then.  (Although the Supercheap ones are still alleged to melt!)

Has anyone bought recently; if so, what impressions to date?

Anyone using these? Price is sharp, specs appear good.

What is the intended purpose? Is it as a trickle charger?  the jaycar description of an alloy chassis and a 25 year 80% efficiency warranty sounds good the fact that it's only 30 dollars makes it cheap enough to try one and see if does what you expect it to do

Yes, a couple of the projects I intend to keep, need trickle chargers to maintain their batteries.

Looks like Iím the crash test dummy for this.  :) Hopefully a better net result than the exhaust experience!

All of a sudden Dr Frankenstein's laboratory pops into my head with CB screaming at Egor "where's the bloody jumper cables!"

By the light of the night, it'll seem alright

I may buy one tomorrow and lay on my back in the sun, solar panel resting on my chest, one lead clipped to a toe and the other to an ear.

Iíve bought one from Jaycar to test, itís the ZM-9050. Will know in a few days how itís faring.

Great banter with the staff about crash-tackling shoppies, worth the price of admission.  :D

EDIT 1: Fifteen minutes on the car and itís already taking effect. Central locking is now restored. I am impressed.

EDIT 2: Itís very ďsensitiveĒ to solar aspect. I make a confession here; apart from solar watches and calculators, this is my first meaningful experience with solar cells. So maybe that observation fits into the ďno kiddingĒ category - I donít know. But inclined behind the windscreen vs fully facing into the sun, there is a significant difference in output.

Itís passed the first test with flying colours. Got my three-year-old lead/acid battery charged enough that the 10A smart charger could finish it off. Solar aspect really is proving critical when you need this level of grunt.

For now Iíll leave the alligator clip terminals and long lead on it, I note the unit has a readily removable back cover over the terminations so it will be easy to modify the output wires, to fit with a discreet plug in the cabin.

Will make a little support of scantlings from the Big Green Shed, so when behind the windscreen it is finding a better angle to face the sun.
