Thanks Frank you rock

It is the job of the charge controller. I will advise the use of a MPPT charge controller. Check the manual for how to set it up to "flooded" or "fla" after you have connected the battery. Always remember to connect battery before solar panels.

Before you use the battery ask the battery manufacture to refill the electrolyte for you other wise the strength of the battery is affected.

OK thanks!

How long have you had the battery for? Did you buy them together? Do you have the float indicators in place, and what is the level showing? You may have to first top up with distilled water and then check with your multimeter across each cell to get more than 2V.

Flooded lead acid

Yes you do

@@smilinsunsmilinsun8056 so i have to buy 24volt equilizer. thank u so much sir.

Get a MPPT charge controller. It will sort out the equalisation of the batteries during charging. Simply set it to the type of battery you connect to it or do that under the "User" configuration if you have the battery's manual.

Once in 2 months is fine

@@smilinsunsmilinsun8056 ok, what i meant was that you showed an equalizer device showing voltages and then the equalization that is done periodically. Is there any need for the periodic equalization if you have the equalizer connected to the batteries

how do we do equalization@@smilinsunsmilinsun8056

​@@odoohub5010no, you don't because the equaliser should do that as needed. By the way, some MPPT charge controllers come with this function (a BMS), particularly when you have more than one battery connected to each other.

In your specific case, replacement with electrolyte is correct because the total volume needed to be restored. The reason only distilled water is used for top up is that it's usually the "water" part of the electrolyte that evaporates during charging, making the mixture more concentrated. Reppacement with distilled water restores the correct concentration. I hope this helps

@@cdoscope thank you for your reply. When the fluid arrived, it was distilled water. They have maintained that if I want to refill, it has to be with distilled water but I should use the float indicators to determine the need for a refill. So, going by the indicators, everything is green. I wish there was an all-instructions manual that would help a user to understand what to do in various circumstances.

​@ekeretteekpo3004 they are not quite correct. Consider the simple logic - if the battery needs say 4 liters of elctrolyte (specific mixture of hydrochloric acid and distilled water, and it spill and loses say 1 liter of that mixture, replacing the 4 liter volume of fluid with plain distilled water will certainly cause a 25% dilution of the electrolyte. In the case of loss of 1 liter volume due to evaporation, its only water that is lost, so you only need water to replace the volume. All in all, it's wiser to heed your warranty provider, but tell them what I wrote and listen to their explanation

@@cdoscope alright. I'll do just that right away. Edit: By the way, since the float indicators (which are also tagged "electrolyte level indicator" in the manual) show green, it should mean that the battery cells are fully topped. So, in spite of the spillage that occurred, the cells are fully topped. I wonder what will happen if I simply added distilled water. Unfortunately, I don't know the mark where the fluid level is supposed to be at. The reason this is a bit of a concern right now is that it appears to me as though the battery was discharging a little bit faster than I was expecting.

@@cdoscope by the way, I have just informed them what you've written and waiting for their response. Thank you for your replies, please.

Flush the entire the battery with distilled water and replace the electrolytes with the battery manufacturers exact SG

@@smilinsunsmilinsun8056 I hope isn't too late boss.. Where do I get the disteeled water from?

​@@abibujimah7342battery dealers have them. They sell distilled water as well as electrolyte.

​@@abibujimah7342from a battery seller. They also have electrolyte.

Ac ​@@abibujimah7342

Yeah that is the very small inverters from 3.5kva and below, the system does that by itself

@@smilinsunsmilinsun8056 thanks for the response.

Lead Acid batteries are not supposed to be left on a standbye mode for a long time. If not charged for a very long time it will sulphate . It needs to be constantly charged and equalized.

The batteries will need to be boosted or so. Take them to a technician who will boost charge the batteries and equalise the cells. That should revitalise them for your subsequent use.

You don't need to take them to technician you can do that yourself with the charge controller equalization.

@@smilinsunsmilinsun8056 okay. I didn't want to sound like an oversabi on the matter. I feel like I have acquired so much knowledge over the past couple of weeks.

Lol feel free Buddy to express your knowledge @@ekeretteekpo3004

This is an indication of a wrong charging voltage

You may need to check your entire set up and be sure that the required voltage is what is delivered to the battery. Even though the tubular battery requires maintenance, it shouldn't be that often.

@@ekeretteekpo3004 you are tight Buddy

After checking your setup, check with your seller or the battery manufacturer or the manual to know its specific gravity. Get a proper hydrometer and distilled water, and top up each cell with the water while checking the specific gravity to be sure it matches the manufacturer's specifications. Before this, make sure to turn off the inverter or disconnect it if you used a MCB breaker between the battery and the inverter. Realise that you may be undercharging and/over overdischarging your battery. CHECK YOUR SET-UP. If you can, use a MPPT controller. They are better suited for non-lithium batteries.

Yeah very soon will let you guys know

The battery no longer retains stored energy, it's probably failed

@@smilinsunsmilinsun8056 It is a brand new battery. at 60% it can last up to eight 5 hours at half load. The battery is an Mpower 220 model. I thought it was a calibration problem...if there is anything like that with batteries.

When you say 60%, what do you mean exactly? What is the voltage reading on the controller?

Thanks for watching kindly visit our website and send us an Email. We will respond to you.

@@smilinsunsmilinsun8056 Sure will! Thanks!
