save a fortune on batteries for solar-set-up
many folk are going to solar power yet finding the expense of the lithium batteries off-putting at the very least
here is a way with break-down of costs over twenty [20] years to save a fortune on batteries and reduce the solar set-up costs
12v lead-acid and gel batteries can also be purchased for a fraction of the price of lithium and most folk do not know they can go to vehicle breaker yards also known as scrap yards and get vehicle batteries for a fraction of the cost of a new battery
and you may also save costs on other things such as cables and connectors switches lights fuses and more plus there could be other things and bargains to help save money for your homestead or mobile-home and-such
for example
where i live i can get second-hand 12v vehicle batteries anywhere from £10 ~ £40 each whereas one [1] new lead-acid battery starts at around £90 for a 60ah ~ 70ah wheres the higher the [ah] the higher the price
thereby if you purchase second-hand 12v vehicle batteries you would be saving them going in the landfill and saving lots of money
and
looking at the high and low price scale for 12v second-hand vehicle batteries
lets calculate costs for a single battery
if second-hand only last five [5] years you can weigh them in get a few bob back or could likely do a swap for a good second-hand battery from the breakers yards or scrap yards or even second-hand vehicle dealers
£40 4x over twenty [20] years is equal to £160 v £4,000 a massive saving of £3,840
£10 4x over twenty [20] years is equal to £40 v £4,000 a massive saving of £3,960
the batteries may last longer as i have seen some folk that claim they are still using their 12v vehicle lead-acid batteries nine [9] years on
£40 2x over twenty [20] years is equal to £80 v £2,000 a massive saving of £1,920
£10 2x over twenty [20] years is equal to £20 v £2,000 a massive saving of £1,980
lets calculate costs for a battery-bank of ten [10] batteries
£40 10x is equal to £400 v £10,000 a massive saving of £9,600
£10 10x is equal to £100 v £10,000 a massive saving of £9,900
£400 4x over twenty [20] years is equal to £1,600 v £40,000 a massive saving of £38,400
£100 4x over twenty [20] years is equal to £400 v £40,000 a massive saving of £39,600
£400 2x over twenty [20] years is equal to £800 v £20,000 a massive saving of £19,200
£100 2x over twenty [20] years is equal to £200 v £20,000 a massive saving of £19,800
lest calculate a new lower end lead-acid 60ah ~ 70ah battery at an average £90 each
£90 is equal to £1,000 a massive saving of £910
£90 4x over twenty [20] years is equal to £360 v £4,000 a massive saving of £3,640
£90 2x over twenty [20] years is equal to £180 v £2,000 a massive saving of £1,820
lest calculate a new lower end [ah] lead-acid 60ah ~ 70ah battery at an average £90 each for a battery bank of ten [10]
£90 10x is equal to £900 v £10,000 a massive saving of £9,100
£900 4x over twenty [20] years is equal to £3,600 v £40,000 a massive saving of £36,400
£900 2x over twenty [20] years is equal to £1,800 v £20,000 a massive saving of £18,200
lets calculate a 240ah new leisure battery at average price of £390
£390 is equal to £390 v £1,000 a massive saving of £610
£390 4x over twenty [20] years is equal to £1,560 v £4,000 a massive saving of £2,440
£390 2x over twenty [20] years is equal to £780 v £2,000 a massive saving of £1,220
lets calculate a 240ah new leisure battery at average price of £390 for a battery bank of ten [10]
£3,900 is equal to £3,900 v £10,000 a massive saving of £6,100
£3,900 4x over twenty [20] years is equal to £15,600 v £40,000 a massive saving of £24,400
£3,900 2x over twenty [20] years is equal to £7,800 v £20,000 a massive saving of £12,200
the costs will vary for area to area country to country thus this is only a guide based on my sources and first hand knowledge
also cheaper quicker more environmentally friendly to replace for most and makes connections with those in breakers yards or scrap yards or even second-hand vehicle dealers
for those in remote areas you may be able to purchase online on places like ebay and have them shipped to you
open for discussion
does this make sense to you or do you have a different point of view…??
p.s
if my calculations are off please correct me as i am not good with math

I am fairly new to solar but have been using car batteries to run my small set up.
The property I purchased has a series of waterfalls out back within reach of the house. Going to water driven power soon.

Often times nothing more than a month long trickle charge will do wonders for old batteries.
-
exactly as the trickle-charge act similar to a desulfator
i have an old battery on trickle-charge as we speak and been on charge since twenty-four [24] January
old school car battery chargers i find best especially the ones that have both 6v and 12v on them
always make sure to open up the filler caps to vent out and top up with deionised or distilled water as required

i took my 12v 70ah car battery off trickle charge a couple of days early as it is now sorted and in use parallel with my other battery on my solar set-up and thus far tests seen to be showing as working well
i now have a 12v [UPS] battery on trickle charge and that will soon be put to good use
i have found that [NOCO] make an affordable 6v 12v combination chargers that include maintainers and delsufator by auto detect for less than £40.00 or USD $48.08 with glowing reviews https://www.halfords.com/motoring/battery-maintenance/battery-chargers/noco-genius1-1-amp-battery-charger-230262.html they also do other models that cost a bit more
not looked into other brands as yet but may be worth looking into

I’ve done the epsom salt and distilled water process on a battery before and i did get extra life out of a battery. Real good if your in a pinch because the process is cheap. Keep baking soda around too because it neutralizes battery acid in case you have a spill.

Interesting info. I appreciate all the help I can get.
I love this community!

you are welcome
that is what we are here for to help where we can and gain the knowledge as we continue to learn from each other
