Leider passen die Batterien nicht in die vorgesehene Öffnung (Batterie ist etwas breiter und länger), d.h. für umsonst gekauft und weiterhin jährlich wechseln. ## Frequently Bought Together - 10x Ultralife Lithium Battery 9 Volt, E-Block, U9VL, U9VL-J 1200 mAh (Economy Set) Set of 10 - Ultralife 9 V Lithium (SLM 9 V Lithium Battery 9 Volt Set of 5 - Energizer Ultimate Lithium AA Batteries (4 Pack) - Double A Battery - 25 Year Shelf Life - Long Lasting Power - 100% Leak Proof Construction --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/53934026-10x-ultralife-lithium-battery-9-volt-e-block-u9vl-u9vl](https://www.desertcart.co.uk/products/53934026-10x-ultralife-lithium-battery-9-volt-e-block-u9vl-u9vl) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-29*
