Let me start by saying this EBL battery combo pack is a solid choice if you're looking for an affordable, bulk option for everyday devices. The 24 AA + 24 AAA mix covers all my household basics - from TV remotes to wireless mice and kitchen scales.
The packaging is compact and convenient, though I do wish they separated AA and AAA batteries into different compartments. Digging through the mixed pile to find the right size can be annoying when you're in a hurry.
Performance-wise, these hold their own against name brands in low-drain devices. My Xbox controller gets about 85% of the playtime compared to Energizers, but at half the price, that's a trade-off I'll take. However, in high-drain devices like digital cameras, the difference becomes more noticeable - I got about 30% fewer shots per battery.
The anti-leak promise seems legit - after six months of use in various devices (including some forgotten in garage flashlights through temperature swings), I haven't encountered any corrosion issues yet. This was a major selling point for me after ruining a nice flashlight with leaky batteries last year.
Where these really shine is value-for-money situations: office equipment, kids' toys, or backup emergency devices. For mission-critical gear or premium electronics though, I'd still reach for top-tier brands. The seller's customer service deserves special mention - their proactive follow-up and extra batteries as a thank-you was a classy touch you don't often see these days.
Bottom line: At this price point, EBL delivers reliable performance for everyday needs with decent longevity and excellent leak protection. Just temper your expectations for high-drain applications.
