Finally charged fully with the pulse repair charger and in desulphurization mode, I'll load test tomorrow and acertain if there's improvement in my ailing battery and update the house if there's improved run time.

Boss, any update?

We await your review....
I learnt something between yesterday and today, I observed that the charger is indeed intelligent and dictects ailing batteries and and switches to desulphation mode and after charging full and I think that's when the repair takes place, like I said earlier I have two ritar 150ah batteries, same make bought same day, I use one at home and the other one in the office, the one at home is failing recently maybe due to under charging because our light at home is too epileptic and I had to rely on my panels for charge and during during this raining season some days was little or no charge. The second one at my office is still top notch maybe because of constant charge because we do have constant light in that area and funny enough this one is always abused because I'm using it for commercial and it's always on from 8:30am till 8 or 9 pm six days a week. My observation was that the good battery doesn't enter desulphation mode after full charge, but the bad one enters desulphation mode after full charge in the right hand indicator while the left indicator will start counting 0.8ah @14.7v, I tested with my car battery which is not top notch and it entered desulphation mode after full charge. So today I decided to carry the batt to my office and charge the battery till it exited desulphation mode because I think that's when the repair takes place, and I've achieved that today because the indicator is reading full charge at 0.0 thou it took up to eight hours on a batt that almost full already. I'll update the house if there's significant improvement when I load test this night.

There really are kind-hearted folks here, and Saint2ace is one of them.

After my above quoted lamentation, I approached Saint2ace about my need to get at least one of these chargers before weekend, and how worried that Jumia may disappoint me.

Without even asking, the baba just offered to give me one of his to use, pending when Jumia delivers mine. We met at Yaba yesterday and I picked it up.

He even gave me a free voltage display for my battery.

Thanks Saint2ace! More blessings!

I believe he's the one that dashed out new battery to ceejays 80 in the earlier years of this thread and he's still helping out, that's one of the aims of this thread, more kudos to you @saintface, keep on keeping on.

they indicated 12v @20amp but I doubt if it's up to 20amp because it took up to six hours to charge my 150ah from 80% to 100%. My other intelligent charger would have done that in less than two hours,

Slow charge is always better than fast charge.

If you check eBay and Amazon, you will see 5A intelligent chargers that cost tens of thousands of Naira if you do the dollar conversion and you wonder why? Deep cycle batteries are best charged at low amps even though they can accept higher amps.

.

Nothing is best than connecting to an inverter plus a specified load at a particular time.After which you monitor with a multimeter or display of the inverter to see how fast or slow the voltage drops at the said load.

Batteries, like I always say, na black market.

Nothing beats a new branded battery when u v the cash.

you've said it all, this their battery tester thingy disappoints, there's nothing better than load testing a used batt, some sincere sellers who value their integrity load tests before selling to customers some use series of 100w former power consuming bulbs in lamp holder to acertain if the batt can hold charge. I've bought used battery from someone here on nairaland which tuned out to be almost useless and when I notified him he started speaking big English and didn't wanna take it back and it took the intervention of well meaning people to settle the issue

so it seems this anjig works differently from the foxsur. the foxsur has pulse/repair mode, and you can select it from the start, immediately you plug it it, i checked with my meter and the voltage flunctuates btw 14.2 and 15.6v with a small pulsing or tick tick sound. so from what you are saying the anjig doesnt have an immediate repair mode, but has to automatically enter that mode after charging?

2ndly the anjig is 400w for upto 400ah batts, while the foxsur is about 100w for 150ah batts max.
which of these units has a better repair function. i can only talk about foxsur, cos i have used it b4, its fairly decent,. though 1 unit malfunctioned and overheated..seems the cooling fan got bad and stopped

I tried charging my rechargeable fan battery with the pulse repair because it doesn't last long again, I just can't explain what really happened, maybe it was the charging amp because the knob was all the way when I was using it to charge the other inverter battery, and funny enough I was there and perceiving the odour small small not until a friend came and complained of the strong toxic smell, I started investigation and found out, and the battery was manageable but now I've completely ruined it

Your first statement is quite correct and the 2 chargers have different functionalities with the same goal, the foxsur is mainly a pulse repair charger with ability to trickle charge while desulphation happens by the pulsing current.

However, the Anjing is first and foremost a bulk charger and only enters the pulse repair mode when trickle charging after battery is full.

So while Anjing is a bulk charger with pulse repair function, the Foxsur is a pulse repair charger with a trickle charger attached, it's a case of heads or tails which wins grin.

But let's also bear in mind, the Foxsur has an 8a max charging capacity, so while it's very good for small batteries such as car battery, golf cart battery etc it will take days if not weeks to fully charge up a decent sized battery and yes the pulse charging starts immediately if programmed to do that but cannot be effective until the battery is fully charge and in a float of at least 13.4v.

The Anjing on the other hand will charge full and begin the pulse charge at 1amp and less and reduces as the internal resistance is chipped away.

So I guess it's a thing of choice, I don't see any of the above being better it all boils down to usage and preference.

Like I always say, the longevity of batteries is based on an understanding of the charging algorithm. If u follow manufacturers specifications u rarely go wrong.

Your battery can bulk charge to 15v and float at 13.8v if u had used the manual setting on the Anjing while charging, then u were charging at more than 16.4v, which of sustained with definitely destroy a cell in ur battery, the more reason it is written in the manual that the manual function should not be used without supervision.

Secondly, if ur battery already had a bad ( u can identify this when ur battery heats up astronomically when charging) then the pulse charger will only make it worse, as it will continue to pump in current to the battery while try to reduce resistance. So In The long run, u'll just get an even bigger problem than u started with.

Lastly, allow the battery to cool down for some hours and use ur rechargeable fan to charge it as normal (slow charge) u might be lucky to get it back the way it was.

We all learn everyday and like I always tell me DIY friends, every mistake is a learning curve.

In less than about 6 hours of using the charger on my Quanta, I am already seeing some improvements.

My 12v inverter has been unable to charge the battery beyond 13.0 for sometime now. The max it manages to do occasionally is 13.2. But I used the charger yesterday and it steadily climbed to 13.4.

We should be having nepa light all through today and I hope to charge it very well by tomorrow morning. I will observe and provide feedbacksb to the house

Meanwhile, I have 2 units for sale here.

eleojo2 is correct the charging current was too high and that was my bad because the knob was all the high where I preset it when I was charging the other big batteries and it didn't cross my mind to tune it down for this small batt, so the house should learn from my mistake and have it at the back of their mind.
Secondly due to the swollen state of the battery it wouldn't fit in the space compartment of the fan anymore so I'm stuck.

eleojo2 is correct the charging current was too high and that was my bad because the knob was all the high where I preset it when I was charging the other big batteries and it didn't cross my mind to tune it down for this small batt, so the house should learn from my mistake and have it at the back of their mind.
Secondly due to the swollen state of the battery it wouldn't fit in the space compartment of the fan anymore so I'm stuck.

if u have an iverter, buy a 12v 5amp power at arena or computer village , connect positive of 12v adapter to positive of 12v fan and negative to negative , make it look neatly done and plug direct to ur inverter or ups

Lol...

In less than about 6 hours of using the charger on my Quanta, I am already seeing some improvements.

My 12v inverter has been unable to charge the battery beyond 13.0 for sometime now. The max it manages to do occasionally is 13.2. But I used the charger yesterday and it steadily climbed to 13.4.

We should be having nepa light all through today and I hope to charge it very well by tomorrow morning. I will observe and provide feedbacksb to the house

Meanwhile, I have 2 units for sale here.

How much is this?

I used gern to charge my inverter and it burnt it. I am looking to replace it with an extra battery.
