Ikea has new LADDA batteries.
They are now of a higher capacity and made in japan. White button top, 4 vent holes. 500 charge cycles.
They are more expensive. The old ones where €3,99 (both AA and AAA) The new ones are €5,99 for AAA and €6,49 for AA
The store I went to still had old AAA’s but no more old AA’s
The website isn’t showing the new ones yet.
I also bought a usb battery charger. VINNINGE They claim it will shut off when batteries are full and has temp protection. 2 slots, 5V 0,5A input, output: 1.4V 0.22A(2xAA) 1.4v 0.11A(2xAAA). Paid €2,49 for it.
From what I can find they will come with more products, including a 12bay AA/AAA charger with LCD in april. At least in the netherlands.
