Does it hurt to leave camper plugged in all the time?
Leaving your camper plugged in continuously can potentially harm its battery system if not managed properly. Most modern RVs with smart converters or multi-stage chargers automatically switch to float maintenance mode, but older units risk overcharging lead-acid batteries, causing water loss and plate corrosion. Lithium batteries tolerate sustained charging better but still require voltage regulation. Pro Tip: Install a battery monitor to track charge status and prevent sulfation in lead-acid models.

What happens to lead-acid batteries when constantly plugged in?
Continuous charging accelerates electrolyte loss and creates thermal runaway risks in flooded lead-acid batteries. Without proper voltage regulation, overcharging generates excess heat and hydrogen gas.
Deep-cycle lead-acid batteries require periodic equalization charges but suffer damage when kept at 100% charge indefinitely. The electrolyte stratifies, leaving concentrated acid at the bottom that corrodes plates. For example, a 12V battery left on a 13.6V float charge for months might lose 30% capacity annually. Pro Tip: Use desulfating chargers monthly if keeping connected to shore power long-term. Transitional phrase: While lithium systems handle this better…
How do lithium batteries respond to permanent charging?
Lithium iron phosphate (LiFePO4) batteries tolerate continuous float charging better but still need voltage cutoff protection. Their stable chemistry prevents thermal runaway below 3.65V/cell.
Unlike lead-acid, lithium batteries don’t require absorption/float stages. A quality BMS automatically disconnects at full charge, preventing overvoltage damage. For instance, Battle Born batteries maintain 98% capacity after 3,000 cycles with proper charging. But what if the charger malfunctions? Transitional phrase: This highlights why…
| Battery Type | Max Continuous Voltage | Annual Capacity Loss |
|---|---|---|
| Flooded Lead-Acid | 13.2V | 25-30% |
| AGM | 13.8V | 15-20% |
| LiFePO4 | 14.6V | 2-3% |

FAQs
Only for unregulated chargers – smart converters maintain safe voltages. Disconnecting prevents parasitic drains but requires periodic recharge cycles.
Can a solar charge controller help prevent overcharging?
Yes, MPPT controllers with float stage management protect batteries better than basic converter chargers during extended shoreline use.
