Sliding a pack of these Energizer-made 6V batteries into my Saflok A28110 lock, I immediately noticed how snug and secure they felt. Unlike some generic batteries that tend to rattle or fit loosely, these ones sit perfectly, giving me confidence that the lock will get the steady power it needs.

The moment I installed them, I appreciated how straightforward the process was. No fuss with complicated connectors—just four easy-to-insert cells.

The energizer brand is a plus—they’re known for reliable alkaline power, so I don’t have to worry about frequent replacements. They fit multiple models, which makes them versatile if you manage several locks.

On the downside, the price is a bit higher than some off-brand options. And if your lock is a different model, you’ll want to double-check compatibility.

Still, for peace of mind and dependable performance, these batteries are a solid choice. They’re a small but crucial part of keeping my door lock functioning flawlessly day after day.

Unboxing these SAFLOK A28110 batteries felt surprisingly reassuring—each pack contains 50 pieces, and the packaging clearly states they’re Energizer-made in the USA. I immediately appreciated how compact the individual batteries are, despite packing a punch with their 6V power.

The fact that they replace multiple models and brands makes them versatile, especially if you’re juggling different security systems. Plus, the pack size gives you plenty of backup, so you’re never caught off guard.

The leak-proof design gave me peace of mind, especially since I’ve had batteries leak and damage electronics before. The triple-layer safety tech seems to do its job, even after months of storage.

That 10-year shelf life is a huge bonus for emergency preparedness, ensuring I can store some for years without worries.
