2020年11月16日 · Second, I bought a 24v battery tender. I bought a NOCO Genius smart tender. It's got electronics to prevent overcharging. It's 7.4 amps, so it's plenty strong enough to charge up both batteries quickly if they happen to both be low. And yes, the NOCO "remembers" its last setting, so when it gets plugged in it's already at 24v without me doing ...

2017年12月18日 · The Humvee Nato (new $47.50) Slave Receptacle J-6362/U 24V came with a fused-in electrical power cord which would have plugged into a 24v charger. In about 5 minutes, I removed the screws on the back of the Receptacle, removed the power cord, and installed the my charger's cable (red to red, black to ground).

2009年2月19日 · The front battery (the one that feeds all the 12V) will be the one dead if you leave the lights on. Connect your jumper cables to the appropriate posts on the front battery (NOT TO THE CHASSIS GROUND) like a normal 12V jump and you will be fine as long as the back battery still has a good charge. Have done this MANY times with absolutely no ...

2020年1月14日 · Managing each battery separately should be best, using two 12 volt units. Batteries are never exactly the same. Each battery needs handled according to its state of charge and physican condition, age, etc. If maintained in series (24v unit) each battery will not get what it needs. This is especially true in vehicles that have both 12v and 24v ...

2020年4月13日 · Installing 12v radios into 24v system is filled with hazards. People who connect their radios across the high side battery wonder why they smoke when they hook up the antennas. Here's the key. In a HMMWV or any 24 volt system you have 2, 12v batteries connected in series to give you 24 volts...

2012年6月16日 · When you use a 24v charger you will never fully charge the weak battery and you will overcharge the stronger battery. A 24v charger will work but you take the risk of overcharging one of the batteries. A 24v charger would be more suited for boosting a truck off but for trickle charging I'd much rather have two separate 12v chargers.

2010年12月4日 · Then trickle charge the 12v battery off the truck system through a 24 to 12v converter. If usage is short term, the 12v battery might get the job done without connection to the truck, then charge it when you get to shore power. A short term charge can be done by running the 24v from the truck through a headlight bulb in series, to the 12v battery.

2024年10月24日 · IE: at either the 0-12v battery + terminal or 12-24V battery - terminal where the jumper is attached. Ground is connected to the 0-12V batt - terminal and the pair of +24v wires are connected to the 12-24v battery + terminal... There …

2024年11月19日 · The real irony here is that with a straight 100A@24v alt, and a 24-12 converter to provide for the truck 12v loads, that 2800W would be large enough to support a 240AH@24v conventional wet cell battery bank and still be below 100% load worst case...

2011年2月28日 · It's the other way around, mcmullag. Starting a 24V CUCV with a 12V car, not a deuce, or a deuce starting a 12v car or truck. The CUCV has two alternators to provide the military standard 24V, but most of the system is just a 12V civilian vehicle.
