Review: Much better value and function for money than other brands. Great batteries. - Really really good value for money. I bought this big pack after testing a smaller pack out. They last absolutely ages with a cat who likes to graze and has his automatic feeder opening and closing about 50 times a day. I get double the length of use out of these with my grazing cat compared to other well known brands, and with my other cat who uses his feeder a bit less throughout the day, we have the same batteries in there well over a year later so I'm really happy. They function much better than other brands!
Review: Good quality batteries - Minimal packaging waste. Good price for the 40 pack of batteries which are good quality and last well. These are much better than the cheap batteries you buy in budget supermarkets. They last much longer and end up being much better batteries. Good quality batteries. I will buy again.
