LADDA, IKEA's range of rechargeable batteries, is absolutely essential for anyone looking to reduce their impact on the planet. Cut costs and waste by making the switch, and you'll never run out of working batteries again. They're compatible with most high-energy items, like portable speakers, toys and torches, and amazingly, you can charge and reuse them up to 1,000 times. You can obtain a charger (STENKOL) and four batteries for £12 ($15.98), which we think is an absolute bargain.
