Werken maar 4 maanden.
Ik kreeg de batterijen 22-12-25 binnen. Gelijk gemonteerd. Eind april 2026 zijn ze al leeg. Een flinke prijs betaald voor iets meer dan 4 maanden beveiliging.

Could you please reach out to us at info@sleepingbattery.com so we can look into this together?

Prima product
Zeer tevreden, ik merk geen verschil in dagelijks gebruik van de sleutel en keyless entry. En fijn gevoel dat hij beschermd is tegen diefstal op het moment dat de sleutel 's nachts op het kastje ligt! Prima product.

Works perfect!
I have used this product for 2 years now and it works prefect. Sometimes I even forget that I have it, because I don't even notice that it is inside my car key.

Very bad company
Very bad company! The sell you 2 batteries but when the first battery is empty the second one is already dead! The don’t give you a new one. So you pay 100euro for only 1 battery! That’s insane!!!

Sleeping Battery Duopack
Product: [Product Name] CR2023 Batteries (Order #CART-01463-61899-WYQ5T)
Purchased: January 2nd, 2024
Depleted FOB battery warning date: October 21st, 2024
Issue: Both batteries I purchased drained to critically low levels within a year. One battery was used in a car FOB, while the other was unused. Jan 2024 to Oct 2024.
Expected Battery Life: CR2023 batteries typically last 2-3 years.
Issue: Normal CR2023 Batteries come with an average charge of 3.0V to 3.4V. The batteries I had bought had reached 2.56v and 2.50v in a matter of 10 Months. The depleted state for a CR2023 is 2.7v. So they must have reached that threshold much earlier than 6 months.
Defective Batteries: The rapid discharge suggests a possible defect in the batteries.
Evidence: I attached pictures of the batteries and their charge states.
Request: I asked for a full refund or replacement for these defective batteries.
Response from info (at) sleepingbattery (dot) com: They said they cannot refund or replace after 6 month (how fitting) but offered a 20% discount. The argument they made was that some cars talk to their FOBs more than others; let me translate that for you: "our batteries will drain within 6 months to unacceptable voltages."
These two batteries cost 70+ Euros. They don't last a year. A simple RF blocker case is a better investment if you still want the security benefits.
