The capacity of my 2013 JBL "Micro Wireless" speaker's 600mAh, 3.7V Li-Po battery (MLP403048) decreased gradually over the years, but it decreased greatly in the 9th year. Originally it used to last for an entire day (7-8 hours) of music listening while snow-skiing in the cold. By 2023, it only lasted ~2 hours in the cold. When I tested it via Bluetooth at room temperature (which is easier on the battery), it lasted ~6 hours. After replacing the battery with this 800mAh Starnovo battery, the same test at room temperature ran for 12.5 hours (at the exact same speaker-volume setting, playing the exact same playlist via Bluetooth at the same distance with the same phone-volume-setting). Hopefully, this battery will last for many years to come. If possible, I'll revise this review if the battery fails prematurely.The original battery had 3-wires; red, black & white. This Starnovo battery also has 3 wires; red, black & yellow. After doing research, I found that the yellow wire seems to have the same functionality as the white wire. It charged perfectly and stopped charging when full.One slight complaint is that the wires were shorter than the original wires, and so (after soldering them in), they were just BARELY, BARELY long enough after stretching them taught. But apparently this battery was designed as a replacement for the JBL "Micro 2" (not my JBL "Micro Wireless"), so maybe the wire length is adequate for the JBL Micro 2. ## Frequently Bought Together - Starnovo 800mAh 3.7V Replacement Battery for JB L Micro 2, Micro II, JBL FT403048P - elechawk 10pcs Upgraded Tiny Whoop JST-PH 2.0 Male and Female Connector Cable for Battery JJRC H36 H67 Blade Inductrix E010 E013 --- ## 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.tw/products/354920316-800mah-3-7v-replacement-battery-for-jb-l-micro-2](https://www.desertcart.tw/products/354920316-800mah-3-7v-replacement-battery-for-jb-l-micro-2) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-04-22*
