Special featuresEnvironmentally friendly (less waste), quick handling, leak-proof Weight (g)approx. 7.6 (per battery) FAQs about the Energizer L92 in a box of 10Are these batteries different from the ones in the blister pack?No, technically they are identical. This is exactly the same Energizer Ultimate Lithium L92 cell. The only difference is the packaging: instead of being individually shrink-wrapped in plastic and cardboard, the batteries are loose in a small cardboard box. This saves space and waste.What is the best way to store the opened box?Cool, dry and short-circuit proof. As the batteries are loose in the box, make sure that no conductive objects (paper clips, coins) fall into the box. If you remove individual batteries, close the box again. Thanks to the lithium technology, you can easily store the box in a cool cellar or storage room for up to 20 years.Is the box of 10 cheaper?Usually yes. As the manufacturer saves the cost of the complex individual sales packaging (blister pack), this price advantage is often passed on to the customer. The "unit price" is usually more attractive for bulk goods than for blister packs of 4.Is this pack worth it for VR controllers?Absolute. Modern VR controllers (e.g. Oculus/Meta Quest) require a lot of energy and benefit enormously from the low weight of lithium batteries (faster hand movements, less fatigue). As you usually have 2 controllers and play intensively, the 10-battery supply is very useful here.
