Ikea ladda ready to use

For those too lazy to look at at post #30

if you use test mode, it will show you the discharge capacity even when it finishes charging (i talk about the bc700, don’t know the other)

Yes, totilde, the test mode on the BC700 will do that - Thanks :slight_smile:

Btw, just comparing prices, the LADDA’s cost around $7.60 for a pack of 4, whereas 4 Eneloops would cost about $17.00 locally.
I’ve no doubt the Eneloops are better; but at this price, it’s too good a deal to miss :smiley:

OK, this is partly correct. But you will be forced to accept the automatic charging of the battery before discharging is done! That way you cannot measure the remaining charge in eg. a newly bought battery.

Besides, often the charger cannot detect when to stop charging a newly bought battery or one that has not been used for a long time. In that case a refresh is the best way to go anyway.

Good charging! :-)

yes, you’re right, to know the remaining capacity you must perform the “discharge” option, and you are forced to be present having an eye on it, to read the value before it starts charging again.
I don’t care much about remaining capacities, when the device stops working i just plug the batts in the charger and let it go

Ikea ladda vs Eneloops; Think Eneloop is still king with AAs 1 amp quick charging against Ikeas 200mA in 15 hours. Also have to see how they match in cold weather. Flashlights in the icebox? No snow here this x-mas. :slight_smile: Merry Christmas!

Edit; I bought plenty of laddas,good to have for give away flashlights.

I have exchanged one of the packages with LSD ones. Thanks for the information.


Well.
The first month waiting is done.
on the 17th of december I gave the LADDA’s their final charge, and today I have done a discharge on AA and AAA #1 (AAA had their final charge on the 14th)
The AA started with a capacity of: 2059
The AAA started with a capacity of: 824.

Today this are their discharge results:
AA: 1774 (86,16% of original capacity)
AAA: 687 (83,37% of original capacity)

I will now start cycling LADDA #1 and eneloop C1 (3th gen) (both used in the first load test)
And see how they perform after those cycles. I’m aiming for 50 1A charge 500mA discharge cycles so it will take some time again before I can further test them.
50 cycles might not be much compared to their estimated cycle lifetime, but it might give a first idea if they will still perform better than the eneloop after that or if they are already failing by then.

I’ll keep you updated :wink:

Thank's for doing the test, Johnny!

I got four packs of AA and four packs of AAA for christmas and I am happy that you are doing the tests for me :-)

Two of my packs of AA are fabricated back in ultimo 2012 but seems OK after cycling. All the others are from ultimo 2013. I guess that frequent filling up of stock can bury some packs at the bottom of the pile.

Today I was at ikea all AA were sold out just a dozen packs of AAA available, so I guess a lot people buy these.

Did you do an initial discharge on those 2012 ones perhaps? Or do you still have an unopened pack of those? Would love to see those results as it’s gonna take a while before I can do a 1year discharge.

Yeah… I bet that’s because people been reading this post :smiley:

My local Ikea outlet also sells ’em out fast. Never seem to get the AAA ones…

Actually I did!

The two packs with week no. 1248 had remaining charge (measured with BC-900 at 350mA):

1362 mAh, 1345, 1393, 1349,, 1383, 1341, 1392, 1407 (average 1372 or 69%). But we cannot know if the initial charge was 2000?

One pack from week 1327 was 1647, 1635, and (strangely) 1313. I goofed one number by removing the battery before reading the result -doh!

For one pack of AAA (week 1310) I got (at 100 mA):

615, 611, 621, 627 (average 619 or 82%)

Unopened I now have 1 pack AA week 1333 and 2 packs AAA week 1341.

I think there are some benefits not to fully charge batteries at the factory. Better life in long time storage, safer in transport or just faster to charge at the factory since you have no slow charge at the end??

Those are some good results!
I got 77.5% after 5 months, so 69% after a year isn’t bad and would fall in line with what I know of LSD batteries. The emptier they get the slower they discharge.

Thank you!

I guess there is no benefit for full precharge because the first percents are self discharged very fast and for long time storage it is best for cell life to have them charged to only70%. The self discharge gets slower with decreasing filling.

I once bought some 3year old duraloops which had still around 1200mAh and the cheapo cells I got had also around 1100mAh after a bunch of years. So I see no problems with all the LSD cells in terms of self discharge.
And these ikea cells seem to be even better cheapo LSDs.

The 50 cycles test would be really interesting.

What charge rate do you recommend for the laddas, both the AA and AAAs?

The label on the battery recommends charging AAs at 200mA and AAAs at 75mA.

But when I look at the ladda charger: Shop Quality & Affordable Products - IKEA CA
It says “You can charge any combination and amount of AA and AAA, up to 4 at the time. The charger will stop charging when the batteries are fully charged (maximum 2.5 hours charging).” Assuming the batteries are drained and full charge,

AA: 2000mAh / 2.5h = 800mA
AAA: 750mAh / 2.5h = 300mA

This means it must use a minimum rate of 800mA for AA and 300mA for AAA in order to complete the charge within the 2.5 hour maximum timeframe.

If that’s not confusing enough, I have the C9000 charger. They recommend .5 C which works out to 1000mA for AA and 375mA for AAA. They also say charging below .33 C is not recommended.

What are your opinions?

For a regular charge I use maha’s recommendation.
1000mA for the AA’s and 400 for the AAA’s
The low current the label mentions is indeed what is recommended for a break-in. Charging 16 hours with 0.1C followed by a 0.2C discharge and a 16hour 0.1C charge again.

That’s what’s on my cycle now. 1A charge and 0.5A discharge. They’re on their 8th cycle now, so still a long road until they got 50 cycles on them.

I was in Ikea and picked up 4 packs of AA and 2 packs of triple A’s , don’t even have a charger lol I also have some eneloops on order. I have a xtar wp6, was thinking is the intellicharge worth it or invest in the maha? Hmmm decisions I think the nitecore is a little high on charge rate for AAA?

My personal experience with i4 is that its not suited for AAA size physically, batteries can sometimes make bad contact with positive end of the charging tips and overcharger battery till its unbearably hot, this has happened twice so far.
For AA’s its too slow.

Hmm, MAHA or something similar might be good investment as long as you know that you want/need all the extra modes it offers.

Theres SHAN charger at Fasttech available for half or even one third the price of MAHA C9000, depending on sales/rebates of MAHA and which part of the world you live in.
Anyway, I bought MAHA and Im happy with it, even tho it seems that mine came with either bad power cord or sensitive 12V port on charger itself, so Im getting replacement sent to me by MAHA 8) !

EDIT - The only thing MAHA folks could change in C9000 is the ability to see all charging ports at the same time, currently its looping through all ports one by one and showing all the information of one port at a time slowly cycling through its information twice(voltage, charging or discharge current, time, capacity) then going on to the next port.
I wish it had option to cycle through one ports data manually and also show data from all four ports simultaneously. Perhaps all is needed is simple firmware update?

Sorry for some off topic :)!

We dont have here anything similar to IKEA, if these are as good you folks report them to be, then for 5$ its a steal!
