I highly recommend these for car key fobs. I had duracell but it kept going low after a week. I had these in the car for a few months. Reallt good and well made!

I have Timex Indiglo watch and change the battery myself. Cheaper batteries don’t last as they don’t seem to have enough juice to power the Indiglo beyond a few months – these are great and last a long time.

Customer Review –
These Energizer CR2032 lithium coin batteries are built for long-lasting power and enhanced child safety features, but at £9.50 for four, the price feels steep.⚡ Performance & Shelf LifeEnergizer has a solid reputation, and these batteries deliver dependable power for everyday devices. The 12-year storage life is a huge plus, ensuring they’re ready when needed without worrying about losing charge over time.They’re also rated for extreme temperatures, performing reliably from -22°C to 140°C, which makes them suitable for both indoor and outdoor use.🛡️ Child Safety Features: Practical or Overkill?The 3-in-1 Child Shield technology adds extra protection—bitter coating, blue dye activation, and child-resistant packaging all work to deter accidental ingestion.While this is great for households with young children, the question remains—are these features truly worth paying a premium for? If child safety is a top priority, these might be worth considering if you have no other means to keep them out of the children’s hands. Otherwise, standard coin batteries at a lower price could do the job just as well.💰 Value for Money?There’s no doubt about the quality, but at £9.50 for four, the price feels inflated compared to other brands. The added safety features might justify the cost for some buyers, but for general use, you may find better-priced alternatives that perform just as well.✅ Final VerdictReliable batteries with excellent shelf life, strong performance, and unique safety measures, but the high cost makes them harder to justify unless child protection is a concern. Great product, questionable value. 🔋

Könnte Leben retten – genial!
Top Batterien mit dem extra Kinderschutz.Die knopfzellen sind überdurchschnittlich teuer aber das ist es wert, sollte jemals ein Kind eine der knopfzellen erwischen. Das kann Leben retten. So eine tolle Erfindung.

Great battery for less money
I mean what is there to say? These are great batteries but in general batteries are expensive and you have to go shop for them. So, order these for less and let thinkassemble.co.uk bring them to you. Easy. Recommended.

Barato y con envío prime
Buen precio, y con envío prime, poco más que decirNecesarias unas tijeras para sacar las pilas, pues lleva un embalaje anti niños que hace imposible abrirlas de otra manera
