Let me start by saying, I go through AAA batteries like crazy in my house. Between TV remotes, wireless mice, and my kid's endless stream of toys, I needed an affordable bulk option. The Waklyte Kenstar 36-pack delivers exactly that.

The first thing that struck me was the price-per-unit value. For basic household devices, these perform just as well as name-brand alkalines I've used before. I popped three into a flashlight and got a strong, steady beam - no flickering or quick drain.

I appreciate the leakproof design (that stainless steel cover isn't just marketing speak). After finding corroded batteries in an old thermostat last year, this feature gives me peace of mind for devices I don't check often.

One heads-up: while advertised with a 10-year shelf life, my batch had expiration dates about 4 years out. Not a dealbreaker since I'll use them well before then, but worth noting if you're buying for long-term emergency storage.

Where these really shine is in medium-drain devices. They've been perfect in my:

• Wireless keyboard/mouse (lasting about 2 months with daily use)
• Kitchen thermometer
• LED night lights

The environmental claim gets a thumbs-up too - no mercury or cadmium means I don't feel guilty when eventually recycling them.

Are they the absolute longest-lasting AAA batteries? No. But for the price, especially when buying in bulk, they offer reliable performance where it counts. I'll definitely be repurchasing when this box runs low.
