I read on another product that these machines can't do that - only boost.** A: Why do people who don't know bother to answer someone's question? It's pointless. Leave the charger connected to your flat battery for a while to trickle charge then try it. You won't start it from flat. **Q: Up to what size engine will it start?** A: started a 2.4 diesel Transit after leaving connected to give battery chance to take a charge **Q: Can this unit be left on charge until needed using a modern optimate charger which monitors battery condition to prevent over charging.** A: The manufactures recommend charging the unit to it full charge and then recharging at 2 monthly intervals. It will start most cars even if not fully charged. I have had mine only for a short time, I managed to start my neighbours car with ease using this unit. I don't think they are designed to be continually charged, but if you have some sort of charger that monitor the level of charge, I would wait till Monday then ring Sealey and ask the support department, they will tell you for sure. Hope this helps **Q: Seller?: my boat engine, a Yanmar 2GM deisel manual says needs a batt capacity of min 70 amp hours (my boat batt is 110). will this be good backup?** A: This battery box is essentially used to start engines when the engine starter battery is flat (discharged). It would not bne any good as a substitute battery.It is a small battery which is capable of delivering a big 'wallop' but then needs recharging. If you want to talk about the needs of boats in particular, give me an email to axemann@hotmail.com. I have owned boats for nearly thirty years. ## Frequently Bought Together - Sealey Rs1312Hv Roadstart Emergency Power Pack 12V 900 Peak Amps Hi-Vis Green - KUNCAN 12V Cigarette Lighter Plug Cable，DC5521 to 12V DC Car Charger Auto Power Supply cable for Portable DVD player, GPS, Navigation,Bluetooth Speakers, Breast Pump, Car Cleaners, 5A fuse,4FT --- ## 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.jp/products/49552464-rs1312hv-roadstart-emergency-power-pack-12v-900-peak-amps-hi](https://www.desertcart.jp/products/49552464-rs1312hv-roadstart-emergency-power-pack-12v-900-peak-amps-hi) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-11-06*
