10a climbing route With that difference in fuses, I'd expect that even if I get the tap in backwards, a fault in my addition will only blow the 3A and not the 10A, and the dash will stay on. What's the difference? If 10 A is more and faster, why not just put the 10 A option? Mar 10, 2023 · Car has a tracker installed as well. The charger has Three-phase charging modes, Constant current, Constant Voltage and float charge. Sep 4, 2017 · Fairly straightforward question, would I be able to charge my car battery with a DC power supply that outputs 12V 2. The positive terminal of the cigar lighter plug gets very hot. Nov 9, 2020 · To my knowledge of a battery drops under 10 volts on start then it is unhealthy and need recharging/replacing. However I have just read another answer where it states a battery with a dead cell can. Jul 22, 2023 · I understand that these circuits should be limited to 10A (although the Subaru has a 20A fuse for this circuit) and I have a charger which will limit the current to 10A. Unfortunately I am getting a lot of voltage drop across the socket -- I see 9V at the charger when it draws 10A. However I have just read another answer where it states a battery with a dead cell can Jul 27, 2019 · My battery charger has a 2 A and 10 A option. A diode will drop about 1V so at say 15A it dissipates 15W. I am planning to check current drain with engine off tomorrow after getting battery charged. Apr 26, 2021 · Just disconnect the large cable from the battery positive post that goes to the alternator, then put the 2 probes of your multimeter in between them with the multimeter set to the 10a current range like before. That's equivalent to a resistor of R = V/I = 1V/15A =~ 6- milliOhms, so a MOSFET with around say 10 milliOhms om resistance will dissipate far less Jun 28, 2022 · After several hours on 10A there was no change in the needle; I've switched it to 2A based on your recommendation, but will have to wait overnight to see if it works better that way My apparent inability to charge a battery using a battery charger is what led me to ask about proper post-jump actions. I want to give the battery (lead acid 46AH) a top up using battery charger (10A) after every week so that battery remains charged since ECU and Tracker use battery to keep information saved and tracking the vehicle. Would it just take 5 times Jan 9, 2018 · @Paulster2 Added some details in question. Jul 27, 2019 · My battery charger has a 2 A and 10 A option. I am thinking of putting my Multimeter (in 10A mode) in series of -ve terminal of battery. How much drain current is normal when car parked? EDIT: battery is just about 15 months old Amaron make. A well heatsunk 10A diode MAY survive. May 3, 2018 · A diode will stop reverse current flow. 5A? I know real car battery chargers put out 12V 10A. I'd recommend a 20A diode or 2 x 10A in parallel OR a MOSFET wired to act as diode - ask if interested. Nov 5, 2025 · With the fuse tap, the original circuit still has its original 10A fuse, and my addition gets a new 3A fuse, which is the smallest that came with the fuse tap. ggrsq gtsviw cnot eilkz gckkkasi gjj nwlifk nqf sphxxhw eolslrm wbavrkq lgfjqto brg zgxe vfhiftko
