Battery Powered vs. Hardwired Smoke Alarms
This means you can have multiple alarms in a house with a few floors, and if one alarm detects smoke, all the alarms will go off. This can be a huge advantage if a fire happens on the ground floor while you''re asleep above; a system that isn''t interconnected won''t alert you to the danger until the smoke gets to your floor, at which point the fire may have grown
Grounding leisure battery : r/vandwellers
if for whatever reason you have your leisure battery connected to your alternator or your car battery through whatever means you have that I would suggest you grounded I personally prefer to have higher capacity and so I ran two wires to the front. if your battery does not have to share a ground I would not and the reason I would do it that way if so you can limit the chances of it
Battery Ground Fault Detection in Transformer-less UPS
the battery voltage to be unbalanced between battery plus (+) to ground and battery minus (-) to ground. A simple high impedance resistor divider network and a voltage monitor in the UPS was used to detect this imbalance and alarm the condition.

Ground Loop
The fire alarm company installed their panel in the equipment room. and ran a ground wire directly to the water main. It''s also grounded from the EMT 15 amp feed directly into the alarm panel. There is no ground wire in the EMT, just the EMT itself. I say they created a ground loop, and the alarm panel is throwing grounding errors.
Low Battery and Overload Alarms
I''m having the same problem. Despite having 51% battery, the low voltage shuts down my entire system and then reboots repeatedly when our AC compressor fires. We have a soft start and up until now, it''s had no trouble handling the load of our unit. For some reason, my low voltage alarms were preceded by four Overload alarms earlier in the evening.
MKVIe Ground Detected Above 3300 RPM
My experience with grounds in solenoid circuits is that a ground in the circuit on either side of the solenoid will result in a 125 VDC Battery Ground alarm. If you draw out a typical solenoid circuit, the side of the solenoid that is connected to the SO terminal of the DTBC or DTBD will always have a nominal -62.5 VDC on it.

6 FAQs about [Battery grounding alarm reason]
Why is the 'ground' indicator on my battery charger on?
GOOD NEWS! So, the "GROUND" indicator on your battery charger is ON. It is probably working properly, and has correctly detected a ground fault somewhere along the dc bus. Most often, it does not mean the charger is malfunctioning. Now all you have to do is identify the source of the fault...and eliminate it.
Is it possible to detect a battery ground fault?
However, from the above discussion, we can see that timely and reliable detection of a battery ground fault may be useful. A battery ground fault occurs when an undesired conductive path develops from any point on the DC circuit to ground.
Are batteries grounded?
In many markets the battery and loads are set up as floating with respect to earth ground, this means that neither the negative nor the positive of the system is grounded. Certain contaminants in the air are conductive and can create a small current path to ground.
How does a battery ground fault affect an ups?
The same condition will exist in a UPS system with a (single) battery ground fault. The unit will continue to run, but a battery ground leakage detection monitor will sense the ground current, and then can trigger an alarm on the monitor, and/or through a “building alarm” in the UPS.
What is a battery grounding strategy?
Grounding strategies are crucial for accurate voltage measurement and effective battery management. Single-Point Grounding ‒ This method involves connecting all voltage measurement points to a common ground point, minimizing ground loops and interference.
What is a battery ground fault?
A battery ground fault occurs when an undesired conductive path develops from any point on the DC circuit to ground. (see figure below) This happens most often with rack-mounted wet cell batteries, where leaked or spilled electrolyte forms a conductive path from a battery terminal to the grounded rack. This can be a shock or fire hazard.
