Good value but low voltage
Original review 'These seem good value, but my alarm sensors are reporting them as low battery as soon as I put them in and they last a fraction of the time that I am used to in some of my sensors, but not all of them, which suggests there is a lot of inconsistency in their performance. I've ended up buying alternatives.' Update 'Outstanding customer service. I received a response to my review and replacement batteries, which work perfectly. I can't give five stars despite the great service, but I am impressed and will now buy again'

ND Tackle fishing bite alarm batteries
I use these for my ND Tackle bite alarms. I found the battery life great and would order again. I always take the batteries out when not in use and found they last longer. Great value for money

Long Lasting
They seem to last longer than other makes at a similar price. Have used them for a number of years now.

Out of date? 3.26v on load (light switch)
There is no USE BY DATE on the batteries or on the box. They measure 3.6v with no load (not the way to test batteries). Under load (about 10mA) voltage drops to about 3.3v (correct way to test these batteries). I believe these batteries are well out of date. Please put the Use By DATE on future sales. Please arrange pick up and refund me. Regards ML PS if they do happen to work in your application, they will not work for long.

Good value for cost
At first I was disappointed because I thought the battery was only charged 76% but the next day it registered 100% Charged with my motion sensor. So I’m completely happy with the purchase

2月保管して使用すると劣化していた
同じものを使って、良かったので大量のパックを購入 2ヶ月保管して、入れ替えて使うと 結局ほとんどが劣化放電して、電圧が足りなくなっていた カスタマーの期限切れなので泣き寝入り

Good, long lasting battery. Very specific size.
These work well. I have a Radon system in my basement which has a small monitoring device, and these are the batteries it requires. The last quite a while, so the capacity is good. They are not rechargeable.
