Good Day Wonderful People,
Please who has ever used a fully refurbished battery and how was/is the experience?
Kindly help out with performance report!

Thank you in advance,

I need help... I bought a 150ah Rita battery Nov 2016 then i could use TV, 2 ceiling fan and 2 bulb from 7pm to 10pm then 1 ceiling and 1 bulb from 10pm to 6am and over bar left on the inverter, but recently I can barely use 1 bulb and 1ceiling fan from 7pm to 11pm.
I read online Rita battery y life span is 10 years
can someone tell what is going or reason why this is happening

Probably it is discharged too deeply,
Or overchaged!

I have someone experiencing same issue,
The battery don fat for here.

The Bosses would brief you more in the morning

Cheers!

any solution to correct it

Pls where can I get mercury inverter 1.2kva inverter fuse. There are 3 fuses of 40A. Or how I can rewire it

Good Evening House,
Please make una help update the thread as e dey,
Those that have been using grade A battery from day 1,
How far?
What are your short comings?
Who else has observe the battery voltage when the ups/inverter goes off?

Under idle conditions it's best to maintain a 50% DOD so you can have like 4+ years from your battery,

Make make una update the house on this beautiful setup performance so far!

Guys, my 200Ah Deep Cycle has been charging for more than 10hrs now and the Inverter(Microtek 1.1Kva) hasnt still indicated battery full till now. Does it take that long to charge up a battery normally? For an inverter that has 12amps charging current...

current might be low or the battery already haveing problem with some cells

Quick calculations:
Charge time = Battery AH ÷ Charging Current
In your case:
Charge time = 200AH ÷ 12A
Charge time = 16.67 hours.
Charge time = 16 hours and 40 minutes.

I went to the the service center long ago. It was a small office in a big building but i got the necessary service. The display panel was changed for free.

Tnx bro, as always.
My inverter has a Charge Voltage & Current selection at the rear, it has a "Steady" and "High" setting, its currently on Steady as it came wen i got it. On the manual, it says it can be adjusted based on the battery spec. Will it decrease the charge time if i set then to High? Plus, wats d possible effect on my batt? I plan to set it to High once in a while dou, nt all d time. Here's a pic wit d selection switch circled in red...

There is one more thing however.

Inverter batteries are not supposed to be discharged to 0% state of charge. That will damage the batteries. So intelligent inverters/chargers will only deplete to say 20, 30 or whatever is the preset. Some inverters have user adjustable discharge selecetor.

My point is that, theoritecally, a 200AH battery will not be completely discharged of its 200Ah charge. So a balance of say 30% should be left unusable. That means a charging time for a battery discharged to 70% of its charge should recharge in 16hrs 40 mins less 30% of the time.

This should be, 11hrs 40 mins if my calculations are correct.

Now, even after the 11hrs 40mins, a normal inverter of charger should not show full charge because the charge should be a 2, 3 or 4 stage charger. This means that jf the inverter was charging at 12A, after 11hrs plus of charging at thks voltage should go to the 2nd stage of charging, then 3rd then 4th. Each stage leads to a drop in voltage. It could mean that buy 90% state of charge the inverter or charger should slow down charging. This stage will add to the initial time if the battery were to charge at constant rateof 12A. Asuuming the final 4th stage is charged at 2A and the state of charge is 95%. 95% state of charge may be say 190AH. The remaining 10Ah will a 2A charge will take 5hrs.

In essense, the apparent charging time is far higher than calculated for these obvious reasons and more. More could be temperature and other factors affecting charging time.

This is not from a text book but from my experience and knowledge.

Brilliant!
So, pls check the pic i posted above, by switching the charging current to HIGH, i guess iv bypassed the multiple stage charging system, rite? Aldou i believe this isn't good for the batt.

From the pix, there are 2 selectors regarding charging. Charging current and charging voltage.

There are standards for these depending on type of battery. For example, my Mercury inverter manual says if i am using a 100Ah or less battery, i should select 10A charging current but if using battery between 100-200Ah, select 20A charging. Your manual should specify the charging current at standard and at High so you can properly say you are right or wrong.

With regards to charging voltage selector, Bulk (1st) stage charging voltage depends on battery type (gel, AGM, Flooded). This is the reason some inverters have battery type selector to determine the appropriate charging voltage. For your case, i think 13.5-14.5v is standard and 15.7v or there about is high. If that is correct, then everyday charging of your inverter at High voltage is bad. That high voltage is sometimes needed for equalizing charge where a battery is heavily depleted say to 0%. The high voltage charge may be used periodically to maintain battery cells but not consistently.

Thats why on most mobile phones, if a battery is heavily depleted and phone is plugged for charging, the battery charging indicator will not show until such atime the battery charge is at a certain level.

The issue here is that your inverter specifications must give you a guide to select these switches.

I'm looking on getting two 12v 100ah batteries with good brand (grade A/ refurbished)

refurbish grade a now available nw 30k

I have been worried since yesterday after a heavy windy storm. Electricity was not restored and i was sure its going to be for the night if worst for a day or 2.

Usually we begin load shedding on the inverter which we did from around 4pm, by 11pm the family had settled in and i just had my shower, the inverter low battery alarm buzzed when i switched the TV and fan in the sitting room. WTF i told my self since i saw 4 full bars like 20mins ago and the inverter usually takes us atleast through the night. I checked and saw 2 bars. Another WTF, since it normally sounds the alarm when the last of 4 bars is gone.

It down on me that my battery is about to give up the ghost. I cant remember the last time i spent money on fueling generator and it downed on me i am soon going to start that else i have to produce 120k for a new battery.

I feel like my mecury inverter mismanaged the battery probably from a low DoD or bad charging. I noticed the bulge on the batterh casing a while back but didnt think the battery will go down so soon.

I used to get at least 12hrs even with heavy usage, now its just 7 with minimal load.

Anyways, i am grateful for the almost 2years it served me. Note that the battery wasnt purchased new, in fact it cost just 15k to get it then.

1 12v 200Ah Gel battery Dekar Solar made in USA. The inverter is 1.2Kva Mercury.

My area has very good electricity supply, power cuts are usually for 10 - 30 mins or cummulatively 2hrs of 24hrs. Atleast we boast of 22hrs a day except when there is a fault locally or on the Nationsl grid.

My battery show signs of bulging which is an indicator for overcharging. I blame my inverter for that.

Iam just surprised u culd get out upto 12hrs from one 200Ah batt, iam wondering wat loads u use on it, abi is it jst a fan and a bulb? Or its cos its a Gel batt? I get like 7-8hrs straight on my 200Ah batt with 1 Ceiling fan, 1 LED 32" Tv, 1 Home Theatre, about 2 11Watts bulbs, Playstation 4, laptop and a couple of fons charging. Dunno if dats normal esp seeing that the Playstation 4 alone is 120Watts wen the GPU picks up for gaming. Aldou if am using the Gotv witout d Playstation4, it lasts way longer, cant really tell hw long sha. Wat loads do u put on urs?
You are lucky to have upto 22hrs of power frm NEPA, on a normal day i get like 3hrs a day, max 7hrs a day, which brings me to wat i wanna ask nw, my batt hardly gets full cos of this Nepa wahala, somtimes i jst use my Gen to boost it up, will dis hav a negative effect on d batt over time?

Good-day, please I want to ask a similar question to the member above, but with modifications; I've recently got myself the same type of inverter you got; 1.2kva Mercury, and tried going for a 200Ah "belgium" battery, cos of the price of a brand new one, but turns out second hand things don't like me either. So went back to seller, and seller advised I go for brand new 200Ah Trailer battery, because it is cheaper, but tells me honestly that he doesn't know about its durability or longevity.

I've tested it on yesterday on the following; Lounge, one 21" hunch back tv = 90w, + its home theater system = 40w + Hd receiver = 20w + one regular ceiling fan (maybe 60w), + one bulb = 11w, total = 221w
Bedroom, one 14" hunch back tv @60w, + its home theater also 40w, + Hd Receiver @ 20w, + one regular ceiling fan @ 60w + one bulb @ 9w, total = 189w. Sum total = 410w.

The battery got fully charged (4th bar on inverter stopped blinking) after like 3hrs, 30mins. (Maybe because I put inverter to 20A charging current). And battery depleted after just about 5hrs, 30mins on the above load.

Questions; please any idea on how trailer battery should function (am I getting good value for my money, considering load and set-up)?
2. Do you think that 20A of charge current on Mercury inverter is too high for the batteries and might subsequently cause problems to it early in life.?
3. I have an Hp Compaq laptop, notice it seems to be consuming energy, as when I turn off tv to conserve last bar on battery, and plug in the laptop, that last bar still complains as though the TVs were still on, (don't know its wattage). So can changing some of my equipments like tv and fan to new modern ones help increase my battery ON time Or is this the number of hours I can continually expect from the battery regardless, being a trailer battery.? In a day we see Phcn like total of 12hrs broken into 4 different sections.

Thanks.

My load is, 32" LED TV, DSTV, Home theatre, Laptop, Standing Fan, 3 ceiling fans, 6 lights (18w each) and a blender for few minutes some days when there is no electricity.

TV is off 6 hrs if am home and 9hrs if am not. 2 ceiling fans are almost constant for nights. During the day almost everything goes off except TV, decoder, home theatre and standing fan.

It seems your load is more than mine.

My battery is always full sometimes for days without considerable use.

Undercharging is as bad as overcharging. I dont think charging with generator will cause you any harm.
