How long does a leisure battery take to charge?
If you have a 100 amp-hour (Ah) leisure battery and you have used it to 50%, you will need to replace the 50Ah. The alternator delivers 5A to the leisure battery; therefore, it will take 10 hours of driving to recharge the battery. If you’re using the mains charger, then expect a max of 3-4 hours.
How long does an alternator take to charge a leisure battery?
If the alternator delivers 5A to the leisure battery, it will take 10 hours of driving to recharge it. Likewise, when using the mains charger, you need to leave it on for long enough to recharge the battery. Most on-board chargers are 15-20A units, so they’d finish the job in around three hours.
What voltage should I charge my leisure battery at?
13.8 volts
Charging the leisure battery Many are designed to work at a constant voltage of 13.6, to 13.8 volts. This level is carefully chosen to prevent gassing and possible damage to the battery through overcharging. However, it is not enough to give the battery a full charge.
How do I know when my leisure battery is fully charged?
If you are looking at the control panel straight after plugging in the EHU, then yes, a fully charged battery will register 14.3 volts with a current of 5 amps or so. But if the batteries are already full (charged by the alternator) and the charger senses this, the current will fall back to around 0.5 amp very quickly.
Do I need a special charger for a leisure battery?
Split charge relays don’t fully charge leisure batteries If you rely heavily on charging leisure batteries while driving, a B2B charger is probably essential because it’s the only way the batteries can be fully recharged. Without this, the battery life is negatively affected.
How does a leisure battery charger work on a car?
This is the most common leisure battery charging method used and is fitted to nearly every van. A split charge relay is effectively a switch, that when closed connects the vehicle and leisure battery together. This enables the vehicle battery, once fully charged to split the charge it receives from the alternator with the leisure battery.

What kind of battery is used to start a boat?
One of these is a marine starting battery (or cranking battery), which is used to start the boat’s outboard motor. Starting batteries are designed to deliver a short burst of high current and to not be discharged to a significant level. These batteries have one primary purpose: to turn the outboard’s starter so you can get underway.
