Let me tell you, these little LiCB A23 batteries are lifesavers for niche devices! I’ve used them in my garage door opener (which suddenly decided to act like a moody teenager) and a vintage doorbell—both woke up instantly. The 12V punch is legit, and the 5-pack means I’m stocked for years.

Pros: The price is a steal compared to local stores (seriously, why are retail markups so wild?). They arrived fresh with full voltage, and the blister packaging keeps them safe. Plus, they fit every obscure device alias listed—GP23A, MN21, you name it.

Cons: One reviewer got duds (yikes!), but mine worked flawlessly. Shelf life is solid, but if your device drains batteries fast (looking at you, car alarms), bulk-buying might not save you trips.

Verdict: For remotes, doorbells, and gadgets that demand A23s, this pack delivers. Just check expiration dates upon arrival—because nobody wants a ‘new’ battery that’s already napping.
