Was having trouble finding this battery in town. Ordered several to take care of my alarm system. Quality battery at a very good price, fast shipping. Was just what I needed.

BatteryJunction.com sent the battery we needed very quickly so our door alarm was non-functional for only a couple of days; and the six packs mean we won't be non-functional as the ten other sensors' batteries wear out. Thank you BatteryJunction.com!

Im using 5 of these for my 1980s ROSTOV CYCLOPS NS3 Night Vision Scopes IR light (laser). Kudos to Energizer for still making these dinosaurs cause I would of been out of luck using Duracells 5420s. Hahahaha see what I did there.

Worked Perfect

Although a common battery for garage door accessories and available from many sources, I chose Battery Junction since I had previously ordered from them.
The batteries came well packaged. Charge was exactly as it should have been.
One issue is the slow delivery time. Glad I did not need it immediately.
In addition, I ordered three of the same type. I only received two. One was a "bulk" battery. Although, I was notified it was out of stock and would be sent later I have not received it yet. I will assume either the new tariff problems that all businesses are now having is creating a back order situation or it is a slow boat from China and has not arrived stateside.
Products and customer service are very good for Battery Junction; please improve the delivery time. Thanks
