Leisure battery top tips summary As a general rule, never allow your leisure battery to discharge below 50 per cent of its capacity. Performance will deteriorate with age. A typical leisure battery can last as little as five years. Winter is often the time when you find out how good your leisure battery actually is.
What voltage is too low for leisure battery?
As a general rule, the charging current should not exceed 0.2C, where ‘C’ is the amp-hour capacity of the battery. Once charged, it’s important to drop the voltage back to about 13.6 volts to avoid damage.
How low can you drain a 12V battery?
12.0 volts or below – At 12.0 volts your battery is considered to be fully discharged or ‘flat’ and should be recharged as soon as possible. The lifespan of your battery will be severely affected if it remains within this voltage range for extended periods of time.
What voltage should a 12 volt leisure battery read when fully charged?
12V or lower
An alternative method of checking the charge level of a battery is using a hydrometer to measure the electrolytes in the cells. The reading should be between 1.1 (discharged) and 1.28 (fully charged).
How low can a caravan battery go?
Depending on your type of battery, you can achieve 20 to 300 cycles (Flooder or Cheap), 400 to 500 cycles (gel) or 600 to 800 cycles ( AGM), while batteries with 5-year-guarantee give 1,000 cycles. Whenever your battery charge falls below 75% re-charge it; never let it level fall below 50%.
At what voltage is a leisure battery fully charged?
Over a period of time, this can cause sulphation of the plates in leisure batteries, due to under charging. Over charging occurs when the battery remains on charge after it has reached full charge (14.40 volts).
How often should I charge my leisure battery?
every three months
Some types are more resistant than others to this phenomenon but, as a rule of thumb, batteries in storage and not in circuit should be charged every three months or so. A lead acid battery will not perform well if it is completely discharged.
What voltage is too low for a 12 volt AGM battery?
The truth is that any lead acid battery, be it a Gel Cell, AGM or flooded batteries such as DCBs, should be cut-off at 11.6 volts. Not doing so increases the risk of damage to the battery and if taken down deep enough into the batteries charge, will ruin the battery.
How low can you discharge a 12V lead acid battery?
Lead-acid batteries can only be discharged up to 50% before irreversible damage occurs. In practice this means that you will only be able to use half of your battery capacity.
Why is my 12V battery 14v?
With the motor running, the multimeter rating should stay in the 14 to 14.5 volt range. Dropping below 14 means either the battery is weak and unreliable for sustained vehicle operation or the alternator is failing.
Does electric hook up charge leisure battery?
If you use mains hook-up, the leisure battery will be being charged by the on-board charger, and in most caravans and motorhomes this is not a very sophisticated system. It can actually damage the battery, this time by over-charging it, causing gassing and drying out of the battery.
Why does my leisure battery keep going flat?
The main causes of battery drain is a faulty leisure battery. The battery may be old, cold or just need to be replaced. A faulty piece of equipment such as the charger or anything connected to the leisure battery could cause a drain.
Can you charge a leisure battery with a solar panel?
A well sized campervan solar panel system is the ultimate way to keep leisure batteries charged for off grid living. While installing solar panels on a camper is relatively simple, it’s important to size the system to meet your needs and choose the right component parts.
What voltage is too low for a 12 volt deep cycle battery?
The lowest limit is 10.5 volts (used in testing) and obviously unsatisfactory in practical use. Experienced RVers try to use no more than 20% to 50% of the energy available in a battery before recharging. That means they never let resting voltage get below 12.5.
How low can a AGM battery go?
It’s a good rule of thumb with AGMs that you should not discharge them to less than about 12.2v which is about 1/2 the rated capacity. That is a good compromise of useful energy versus the lifetime of the battery. At that rate you might get 3–4 years of continuous use out of the battery…
How low can you run a AGM battery?
AGM offers a depth-of-discharge of 80 percent; the flooded, on the other hand, is specified at 50 percent DoD to attain the same cycle life.
How long should it take to charge a leisure battery?
A 75 per cent charged battery may only take a few hours to charge fully, whereas a fully discharged battery may take more than 24 hours. It is better to do this in up to 12-hour sessions than all at once.
Can I charge my leisure battery with a car charger?
There is nothing wrong with using a car battery charger to charge a battery that is described as a leisure battery. The important point is that it should not be left charging a battery for long periods of time…….so it is not a charger for people that want to fit and forget. You do need a smart charger for that.
How long will a leisure battery run a 12v fridge?
You’ll only get about 5-6 hours from an 85Ah battery on a 12v coolbox, so it’s not worth trying for camping. Get a 3 way (gas/12v/240v) powered fridge – they are much better.
Are Aldi Battery Chargers any good?
Aldi Car Battery Charger – waste of time and money.
I have just bought this and I have had similar problems to others. The Mode button doesn’t change the function as specified in the user guide so it looks like it thinks the battery is a 6V battery not a 12V battery. Probably only good to trickle charge.
How does a leisure battery charge in a campervan?
Most motorhomes offer two methods for charging the leisure battery: via the on-board mains charger when on hook-up and from the engine-driven alternator when on the road.
