In other words, regardless of what the charger is doing can I say, select 6amps or some other number to charge batteries at a slower rate?** A: No. It uses a charging profile for the type of battery and mode selected (DIP switches). By mode I mean you can set it to be a power supply, battery charger, or combo power supply / battery charger. When in the last mode, it doesn't go into the boost phase (highest voltage) at all because it can't tell what current is going into the battery vs going into the load. If you have a constant load, you'll end up toasting your battery because it will sit at a high voltage for too long. I believe if you find the manual for one of these, it will describe the various charging profiles in more detail. I think it starts off with constant current for lead acid and then switches to constant voltage. But I don't think you can control the exact values. **Q: Would this be suitable for use on a fishing boat? Would an occasional sprinkle/splash of water or rain drops damage the unit?** A: The Samlex units are rock solid, and weather/water resistant. I have one installed on a 28' Boston Whaler Center Console and I have had no problems. ## Frequently Bought Together - Samlex America Samlex Solar SEC-1250UL SEC-UL Series 12V Battery Charger,Black - Blue Sea Systems 7184 285 Series Circuit Breaker, Surface Mount, 60 Amp, 48V DC - Bay Marine Supply MRBF Terminal Fuse Block Kit (Fuse Included) – Single Stud 5/16" (M8) Compact Marine Rated Battery Fuse 250A --- ## 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.co.th/products/208400714-samlex-solar-sec-1250ul-sec-ul-series-12v-battery-charger](https://www.desertcart.co.th/products/208400714-samlex-solar-sec-1250ul-sec-ul-series-12v-battery-charger) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-24*
