The best way to optimize your battery’s performance and extend their life is by giving them regular battery care and maintenance. Today, we’re gonna talk about the best practices for regular battery care and I’m gonna show you what happens if you’re a slacker like me and don’t do enough regular maintenance on your lead acid batteries

WATERING
During the process of charging and discharging your lead acid batteries, Water is consumed and Hydrogen gas produced and vented out the top of the batteries. When enough time has passed and water is consumed, the water level in FLOODED lead acid batteries will drop and expose the lead plates inside the battery casing. Lead plates exposed to air will corrode and ruin their performance. They need to stay submerged in the sulfuric acid solution in order to work properly and prolong the life of your battery. The proper solution should be about 3 parts water to 1 part acid. In order to maintain this solution, it’s best to top off the water in your flooded lead acid battery cells about ONCE PER MONTH. Use only DISTILLED water and follow your battery manufacturer’s guidelines as to the appropriate fill level. Any other water (like tap water or even rain water) will have minerals that will harm your battery and cause it to self-discharge rapidly. Make sure your batteries are fully charged before you top them off with distilled water. This ensures the proper electrolyte balance within the battery and keeps it running in good condition.
STORAGE:
In order to get the best performance out of our batteries, we store them inside our home in a wood box. If you do store them inside, it’s very important to vent the Hydrogen gas to the outside air, which is exactly what this 2” pipe right here accomplishes. If you store them outside, avoid places that may be exposed to freezing temperatures, which can destroy the lead plates.
TESTING YOUR BATTERY’S STATE OF HEALTH (SOH)
The most reliable way to test your battery’s state of Health is to Use a Hydrometer. A Hydrometer measures the Specific Gravity of the Acid Solution inside your battery. Consult your battery specs to determine how the specific gravity reading correlates to the percent of charge of your battery.
For a quick check, you can use a Volt Meter to measure the open circuit voltage of each battery. Place the positive probe on the positive terminal and the negative probe on the negative terminal. The batteries should read within one tenth of a point. If they are widespread like here, you will need to EQUALIZE the batteries. Equalizing the batteries is basically when you supercharge the batteries with a higher voltage, which makes them boil. This process breaks up the sulfate crystals that build up on the lead plates. It also reverses acid stratification (where the acid is concentrated at the bottom of the battery) and makes the solution more uniform. This ultimately helps the battery charge and distribute power more efficiently. You can do this with your solar array (like I do) or with a generator. Trojan battery has an excellent reference manual and tips on equalizing. Check out the link in the description below for more information.
www.trojanbattery.com/tech-su...
CLEANING:
When exposed to air, the acid crystalizes on the battery posts, which can interfere with battery charging and power distribution. Its best to keep up with the cleaning so it doesn’t get out of hand. Otherwise you’ll end up like me and have to replace corroded ring terminals, or replace the battery cables altogether. Which can get expensive and cause your battery’s state of health to decline RAPIDLY.
SAFETY FIRST: make sure to disconnect the power to your batteries before you attempt to clean them. I like to take a teaspoon of baking soda and mix it in a cup of water. Then take a toothbrush or wire brush and clean all the terminals. The baking soda neutralizes the acid and makes it safe to work with. Although I still wear gloves and safety glasses. disconnect the bolts and battery cables so that you can completely clean all surfaces of the terminals and posts. Then simply dry them with a clean rag, reconnect the battery cables, and you’re done!
Over the years, I neglected to disconnect the cables and didn’t get a really good cleaning.
I didn’t even realize that my battery cables were almost fully corroded until I started having trouble getting my batteries fully charged. Don’t wait that long. It’s really bad for your batteries to discharge so deeply and will ruin them quickly. I had to buy new terminals, a crimping tool, and heat shrink collars to rebuild every single battery cable. I got lucky and was able to reuse the same cables, and I caught it before my batteries suffered too much. But don’t push it. Batteries are EXPENSIVE to replace. It’s much easier to keep up with them with regular care. You’ll get the best performance and peace of mind.

Its good to cover the terminals with grease (Im pretty sure any type should work fine for this) to avoid corosion due to acid x air reactions. Its good to clean and recover with grease once a year (some querosene to get the grease off).

Ventilation is the key, that box looks all neat and tidy but the venting gasess have nowhere to go hence the copper is reacting and slowly etching away. A couple of small cooling fans should do the trick just to keep the air flowing...

the stuff you clean of the terminals is copper sulfate from sulfuric acid reacting with copper, it would make sense that you could probably stop it by just wrapping it in tape, just a guess.

Your charge controller should have a manual or automatic setting for equalization. Make sure the batteries are fully charged and that you have 4 hours of full sun ahead prior to running an equalization voltage.

I've just been shopping for a new hydrometer and stumbled across this vid. I'm tired of the cheap siphon/float types I've been using. This is the first time I've seen a refractometer used for this purpose. Suitable models seem to be available around the same price as decent hydrometers so I'm going to look into this more. Coincidentally I've been asking for years if there isn't a digital instrument, and just discovered one being sold on Amazon and eBay under various brand names for a couple hundred bucks CDN. I wonder if they're any good. Misco has one for about USD 300 too. My worst battery fail happened while attending school away from home for a year while my wife held down the solar-powered fort. Many weekends during our Canadian winter I would drive home to visit and run the generator to make sure she wouldn't have to mess with it during the week. Didn't watch electrolyte level closely enough and ended up below the top of the plates by the time I checked, permanently reducing my bank capacity. Ouch. Ten years later I still have those batteries though. They've been awesome notwithstanding that I seriously dented them when they weren't even very old.

I accepted the option of having them supplied in pairs. Each pair is permanently interconnected and enclosed in an open-top plywood box with rope handles. They have cylindrical plates, which appealed to me for "long story" reasons, and were recommended to me by a dealer who described them as motive batteries. I will always remember him saying that they were pretty much bulletproof "as long as you don't let the electrolyte get too low." Sigh.

I don't know what the strength of your electralite is - battery's that use weaker electrlite have substantially longer life cycles - My grandfather was an early 1900s generator man - from 1890.till the 1960s 100s of thousands of rural homes were powered by 16 cell 32 volt battery banks in the US and world wide - I can remember going to rural homes and my grand father saying they have a 40, 60 or 80 yr battery bank - That simply meant they should get a 40 yr service life from the battery's - In the deep South many Banks were set.up as 60 & 80 yr banks - Today most lead acid battery's are sold with an acid strength of 1.275 at full charge for domestic use - most farm lighting battery's were set up with 1.190 to 1.220 acid strength - down here in the deep South it was common for batterys to obtain a service life of 60 to 70 yrs when used in rural homes they used 1.190 acid strength in 60 yr battery banks - some used weaker acid - There were many camps in the swamps and marsh that used the 80 yr battery's - meaning the acid was very weak 1.190 ( that was what was used in most battery in the early days at 1.190 at 78° f the standing voltage is 2 volts - Battery's with weak acid self discharge very slowly so they only have to be charged every 18 months when unattended - 1.220 has to be charged every 6 months down here when unattended - in a charged state 1.220 will not freeze till minus 17°F - The tempriture often determined the acid strength in different areas of the country - I presently use a 9.5 kw bank of battery's - it's just used after hurricanes and ice storms these days - I also prefer to use a 12 volt system over 24, 48 or 120 volt system - I did work the offshore oil fields and remote mountain oilfields as SCR electrician for decades - To this day lead acid battery's are the preferred battery above all others for stationary application - There many reasons why - I'm 3rd generation - if you replace Your bank I would recommend just replacing the batteries with golf cart battrey's there good battery's - If you lower the acid strength you will also lower the capacity of the cells - my golf carts are rated at 225 amps at 1.275 but at 1.220 there rated 40% less capacity - at 225 amps the 50% discharge rate is 112 amps at 1.275 acid with 1.220 acid they only have 60% of there capacity so the usable capacity of the battery is 67.5 amps - On the other hand golf cart battery's are mass produced and are in expensive - so you can have a large bank of battery's that are inexpensive - For 40 yrs I had a bank of 100 golf cart battery's with only few failures over the decades - I have a 9500 watt bank now - I sold the 100 battery's for there core price 10 yrs ago and there still.in service there set up with 1.190 acid - when you get new golf battery's you simply make sure the acid is at the eye - then syphon or draw the acid off to the top of the cells - then top the cell off with water - It will take a week or less for the water to mix with the acid - at that point it will be around 1.245 - If you draw the acid off a second time and top the water off again the acid will be around 1.225 - that's close enough - When you charge and discharge the battery's the acid gravity will always be a few points off - it's the same when equalized - If you want spare battery's on hand just take a battery fully slow charge it - then dump the acid and save it - then refill the cell with water and let it set 24 hrs dump the water out - do that 2 more times - Then let the water drain out a few days - it's now a dry charged battery air does not react with lead - save the acid, if you need the battery just add the acid back in and charge it at a slow rate a few days - also get a box of new acid from a auto parts store - When the old acid is poured back in the battery it will loose some strength and have to be adjusted with new acid - In 10 yrs I've cycled the battery's I have over a 1000 times the plates still look new - there not swelled or shedding - out of 26 battery's I've had one failure last month - Also parallell all your 6 volt battrey's together and have the parallel banks series together - If on batterys fails it won't effect all the other series of battery's - At lower strength acid you will have to adjust the peak charge voltage and equalizing voltage - You will find there to be very little corrosion problems - vasilen is the better of lubricants and has been recommended for battery's for 140 + yrs - At 1.275 it's hard to get more than 10 yrs out a battery - if for some reason a battery sulfates bad then then charge it for 5:minutes with a welding machine that generates DC voltage after the voltage reach double the battery's rated voltage or it's gassing good - you do that 2 to 6 times allowing a hour for the battery to rest 1 hr each time - Charge the battery back up.as long as there are no shorted or open cells - the battery will be de-sulfated - Battery's that use 1.190 acid they would add magnesium sulfate ( Epson salt) to the acid to decrease the internal resistance of the cells using weak acid - When using battery's with 1.275 acid when the positive post is loose or can be shaken that battery's life cycle is finished - the acid will eat the post out at that point when using .275

I know what you meant, but some of the terminology you are using is incorrect. Inverters don't charge batteries. Inverters "invert" DC current from a battery into 120-volt (not 110) AC current. A converter on the other hand "converts" 120-volt AC from shore power or a generator into 12-volt (or 24v or 48v) DC current to charge a battery.
