Many built-in battery chargers in a motorhome typically top out at around 13-6-13.8V, to avoid this happening. That’s a sensible precaution inside the confined space of a motorhome, but hooking the battery up to an intelligent ‘staged’ charger in a well-ventilated area is an excellent way to protect your battery investment.
The industry body for the caravan and motorhome industry has a rating system to help owners choose a battery that is suitable for their requirements. Buying a cheaper model isn’t necessarily a problem if your needs are fairly modest. The NCC rating system classifies leisure batteries as A, B, or C.
The reserve capacity of deep cycle batteries used in RVs (including lithium batteries) is represented in Amp Hours. For example, a 12 volt RV battery with an Amp Hour rating of 100Ah means the battery can power a continuous 100 Amps of current for one hour before it is fully depleted. This maximum output over one hour is simply a benchmark.
The longevity of a motorhome or campervan leisure battery depends on frequency of discharge, depth of discharge and how soon it is recharged. A regulator or controller will ensure your battery runs through this charge and discharge cycle regularly. Follow our tips to keep your deep cycle battery in optimal condition:
The upside is the simplicity of maintaining such a simple electrical system. The downside is that it is very easy to flatten the battery by leaving a light on and you will then be on the phone to the RAC in the morning to request a jump start. That is why motorhomes typically have a second battery.
To do so can have a damaging effect on the battery and will certainly shorten its life. Trickle charge leisure batteries when your motorhome is in storage. This will help prevent sulfation and maintain battery life (a lithium battery does not require this). Clean battery extremities and keep battery terminals and covers free of dust and corrosion.

Our current motorhome has 220ah across two batteries and our new expedition truck has a battery bank of 420ah across three batteries. The discharge cycle specifies how many times a battery can be discharged and charged without reducing performance or capacity. 1000 full cycles simply means it can be charged and discharged 1000 times.

I''ve recently started having a bit of trouble with my car. I typically drive my car to and from work each day. A couple weeks ago I went on vacation and when I returned, my car battery was as dead as could be. The battery was already a couple years old, so I went to the local auto parts shop, purchased and installed a new battery.

What is the power output of a USB port?
A unit load is defined as 100 mA in USB 2.0, and 150 mA in USB 3.0. A device may draw a maximum of 5 unit loads (500 mA) from a port in USB 2.0; 6 (900 mA) in USB 3.0. As power is equal to current times voltage, all you have to do is multiply 5V with the current the device is drawing from the port.

A standard starter battery is designed to produce a high peak current to turn an engine over, typically over 1200rpm down to a temperature of -30°C. This is necessary to overcome the mechanical and thermal resistance of the engine, and depending on the engine design and standing temperature, requires cranking current up to 1000A.
