Please update via the ISDT official website (PC required). **Q: What is Destroy mode used for?** A: Destroy mode safely discharges batteries before disposal. It is designed for damaged or unwanted batteries and is not intended for normal daily use. **Q: Why are some modes unavailable for my battery?** A: Certain modes depend on battery chemistry. For example, Storage mode only supports compatible Li-ion, LiHV, and LiFe batteries. --- ## 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.hk/products/60442109-c4-evo-battery-charger-analyzer-smart-aa-aaa-18650-rechargeable](https://www.desertcart.hk/products/60442109-c4-evo-battery-charger-analyzer-smart-aa-aaa-18650-rechargeable) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-07-12*
