Amazon Basics 24-Pack 9V Alkaline Batteries, 9V/6LR61, 5-Year Shelf Life - for Smoke/CO Detector, Electronics & Audio

Packaging was minimal, and, due to the small of size of the batteries and packaging, they are very easy to bring with you and store. I am unsure of capacity, but have been using them in my guitar Pedal for about two weeks and have been playing every day and one has lasted much longer than I thought it would. In this I am pleasantly surprised. For reference I am using them in a Dunlop Cry Baby Wah Pedal, for such an appilcation they work a treat, and realistically should be useable in any other 9v appliance.

For use in my active bass guitar. Not yet sure of the longevity of these whilst in use, but so far seem to be fine. The problem is one of trust. I have always used more expensive black/copper brand, but the cost of them is becoming excessive, so though I'd give these a shot. Sadly, they havn't improved my bass playing though:)

These Amazon Basics 9V batteries offer excellent value for money, especially with 12 included in the pack. I've used them in smoke alarms, test equipment, and other household devices, and they've provided reliable, long-lasting performance. The batteries arrived well packaged and with a good shelf life, making them ideal for keeping as spares around the house. For everyday use, they perform just as well as many more expensive brands at a much more affordable price. A dependable, cost-effective choice for anyone who regularly uses 9V batteries. Would definitely buy again.

These batteries are very good quality at a very reasonable price.

They do exactly what they advertised. Not brilliant but fit for the job.

Decent price now all inserted into my smoke alarms. Had these before and they last. Seems to be well built and much cheaper than other well known brands. Took a star off because it’s just a battery!!

I have ordered these batteries for the second time because the previous ones have lasted for a full year in my ultrasonic pest deterrents. Unfortunately, I live on a road with a serious rat problem, and after an incursion into my loft space by rats, I bought the devices to keep them out. The instructions said that the batteries should last 6-9 months. These batteries have lasted much longer. I cannot comment on their performance in a motorised device, but they exceeded my expectations for the above-stated purpose.

de toekomst zal uitwijzen wat ze waard zijn

Excellent price and quantity for backup of smoke alarms

量と質は十分満足できる

Geniales pilas, a un buen precio
