Seem to recharge and hold charge well. Would purchase again. ### ⭐ Not a true 700mah battery *by B***N on Reviewed in the United States πŸ‡ΊπŸ‡Έ on June 6, 2020* I have 2 of these batteries, one doesn’t preform like the other. I have put them on my smart charger for my other R/C vehicles, but it will not come up to the advertised 700 mah, advertised. The other makes the little boat I bought it for, almost to fast for my pool. I figured these should both preform the same. Sadly, I missed my window to return or exchange. Should you purchase these batteries, do not settle for them if they do not preform correctly, exchange them until you have 2 that operate the same. ### ⭐ Defective *by J***Y on Reviewed in the United States πŸ‡ΊπŸ‡Έ on June 16, 2019* I purchased 2 of these to replace the ones in my boats. After trying both of these I figured my boats were busted because neither boats worked with these new batteries. I made the mistake of throwing out the old boats and buying brand new ones (same TR800 models). I got the new boats and these batteries still don’t work. I’ve tried charging them overnight and still no luck. I can see receiving one bad battery, but not both! --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/61027128-feilun-test-qualified-700mah-3-7v-high-power-rechargeable-li](https://www.desertcart.vn/products/61027128-feilun-test-qualified-700mah-3-7v-high-power-rechargeable-li) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-04-23*
