In my grand battery testing ( http://ammo1.livejournal.com/669120.html) IKEA batteries were the best in terms of price / quality.
In August 2016, new batteries and chargers for them in IKEA stores.
In a new series of four types of batteries: AA 2450, and 1000 mAh, AAA 900 and 500 mAh. They are, respectively, 499, 249, 349 and 199 rubles for four jokes (~ 125, 62, 87, 50 rubles apiece).
Small and light charger Winning device for two batteries AA / AA, connected to any charging of smartphone / tablet with USB output, worth 199 rubles. Large STORHOGEN charger for 12 batteries, which can be hung on the wall, it is worth 2499 rubles.
I tested the new batteries and chargers.
All batteries are made of Ready to Use Technology (or LSD). This means that they are sold and charged for a long time do not lose their charge during storage after charging.
For batteries of smaller volume (AA AAA 1000 mAh and 500 mAh) manufacturer guarantees 1500 charge-discharge cycles, greater capacity for the battery (AA AAA 2450 mAh and 900 mAh) - 500 cycles.
All batteries are made in Japan.
With very high probability we can assume that they are made in the same factory and with the same technology, that famous Eneloop, which previously marketed under the Sanyo brand, and now under the Panasonic brands and Fujitsu. Here are just Eneloop Pro AA 2450 mAh stand in Russia from 330 rubles for a joke, and even in the cheapest Dutch online store ru.nkon.nl they are sold at 2.1 euros per share (currently around 150 rubles), and in the IKEA 2450 mAh AA batteries are 125 rubles apiece.
To accurately determine the capacitance I used Analyzer Oleg Artamonov. 2450 mAh AA batteries were discharged currents of 500 mA and 2500 mA, the remaining battery current of 200 mA. All batteries were discharged first pre-charged to check how much energy is left in them after they charged at the factory.
Batteries discharged to a voltage of 0.9 V. In my possession were 4 copies of each battery, I tested everything.
Batteries IKEA LADDA AA 2450 mAh 703.038.76
The discharge current of 500 mA.
Actual capacity - 2460-2540 mAh, which is higher than stated in the 0.5-3.5%. The difference between the worst and the best instance - 3%.
The discharge current of 2500 mA.
The discharge current of 2500 mA - very hard mode for batteries in which they are very hot. In real life, no one hurts the consumer because no batteries. There are only consumers (e.g., flash and camera flash) that consume a very high current for a few seconds, but after that the battery has time to "Returned to life."
In this mode, the batteries have shown extreme capacity 2310-2390 mAh. Excellent result!
The capacity of the battery taken out of the packaging (production date 07.16, so that they are kept less than one month) was - 1810-1860 mAh, ie about 73% of full capacity.
Batteries IKEA LADDA AA 1000 mAh 203.038.74
The discharge current of 200 mA.
Actual capacity - 1020-1040 mAh, which is higher than the stated 2-4%. The difference between the worst and the best instance - 2%.
The capacity of the battery taken out of the packaging (production date 04.16, storage time - 4 months) amounted to - 790-820 mAh, ie 77-79% of the total capacity.
Batteries IKEA LADDA AAA 900 mAh 903.038.80
The discharge current of 200 mA.
Actual capacity - 930 mAh, which is higher than the stated 3%. Copies are almost identical.
The capacity of the battery taken out of the packaging (production date 06.16, storage time - 2 months) amounted to - 620-630 mAh, ie 67% of full capacity.
Batteries IKEA LADDA AAA 500 mAh 303.038.83
The discharge current of 200 mA.
Actual capacity - 510-520 mAh, which is higher than the stated 2-4%. The difference between the worst and the best instance - 2%.
The capacity of the battery taken out of the packaging (production date 04.16, storage time - 4 months) amounted to - 390-400 mAh, ie 76% of full capacity.
Excellent battery! All of them have even slightly higher capacity than stated. Battery High Capacity suitable for devices that consume a lot of energy (cameras, toys motors, joysticks), smaller capacity batteries for devices consuming small (clock, remote mouse and keyboard). When choosing it is worth remembering that the smaller capacity batteries have three times more charge-discharge cycles, and means "will live" longer.
Chargers Winning and STORHOGEN
Both chargers use a small current charging mode. This charging takes more time, but it is believed that the charge a small current can prolong the life of batteries.
Winning 403.036.32 charger charges one or two AA / AAA battery, connected to any charging for smartphones or tablets with USB output.
Apparatus cheap, compact and light (total 39 grams). It can even be used to charge the batteries AA / AAA in the way of mobile battery (poverbanka). Single white LED is lit while charging, goes out when charging is completed, and flashes when something went wrong.
AA batteries are charging device current 220 mA, the battery AAA - current of 110 mA. This means that the charge for the four types of batteries will take the following times:
AA 2450 mAh - 12 hours;
AA 1000 mAh - 5 hours;
AAA 900 mAh - 9:00;
AAA 500 mAh - 5 hours.
STORHOGEN 603.036.50 charger can charge from 1 to 12 batteries. It is designed so that the charged batteries can be stored directly in it. The device can be hung on the wall. He has a door that covers the battery compartment. The device with the door closed resembles a locker key.
The top row of batteries installed "upside down" - plus-down contact. A liquid crystal display device shows the charge level. For each battery charge level is displayed four - of the full discharge (shown blank battery symbol) to full charge (three risks inside the battery symbol). If the battery is not installed, the battery symbol for the corresponding slot is not shown.
Animation image when there is no charge. Blue illumination indicator operates minute after any installation or removal of the battery or after the opening of the lid.
AA batteries are charging device current 250 mA, the battery AAA - current of 110 mA. This means that the charge for the four types of batteries will take the following times:
AA 2450 mAh - 10.5 hours;
AA 1000 mAh - 4.5 hours;
AAA 900 mAh - 9:00;
AAA 500 mAh - 5 hours.
Charger "smart" - it examines the degree of charge batteries inserted therein, and displays it correctly. When all the batteries are charged, the charger first, consumes 0.2 W, and then goes into sleep mode, while consuming less network from 0.01 watts.
At IKEA stores are now being sold is actually the best batteries on the market at the lowest price. Two new chargers in many respects unique, too.
