This will happen with say an older usb power adaptor. Try (i) charging less batteries at one time (ii) getting a new power adaptor that is rated for usb c or (iii) just plugging it into something that can supply enough power such as a PC. **Q: Will they discharge if left connected to the unplugged charger? When not in use, would be handy if I can leave connected to protect the terminals.** A: No definitive answer on this in my experience if kept on the charger and briefly plugged back in prior to use they may show charging briefly (5_10 mins max) but this may be due to lithium batteries normal nominal loss while stored (much less than nic cads) rather than any effect of the storage being in the charger. **Q: Are these batteries the same measurements as everyday standard 9 volt batteries. Please.** A: I only use these type of 9volt batteries so I couldn't say if they were the same measurements as alkaline ones. They last well until needing recharged **Q: can you charge these on a standard multi battery mains charger** A: Yes, assuming there are the appropriate "press-stud" contacts on your multi-charger. This is exactly what I have. Additionally, the batteries arrived with a coupon to claim a free charger, specifically for the 9 volt batteries. ## Frequently Bought Together - 9V 850mAh Rechargeable Batteries and Charger,Kratax 9V PP3 Lithium-ion Batteries,Low Self-Discharge High-Energy Battery with 600 Cycles,[4 Pack Batteries +1Pack Charger] - JJC Moistureproof Battery Case Holder for 4X 9V Rechargeable Battery, Batteries Storage Box Battery Organizer Case - Duracell Plus 9V Batteries (4 Pack) - Alkaline - 100% Life Guaranteed - Reliability For Everyday Devices - 0% Plastic Packaging - 5-Year Storage - 6LR61 MN1604 --- ## 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.tn/products/176399900-9v-850mah-rechargeable-batteries-and-charger-kratax-9v-pp3-lithium](https://www.desertcart.tn/products/176399900-9v-850mah-rechargeable-batteries-and-charger-kratax-9v-pp3-lithium) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-10-01*
