Leisure Battery Help, does it have to be manually charged?

Recommended Posts

Hi all,

 

After about 20mins of Work this morning my water shut off and the pump was saying the leisure battery was flat.

i have the battery on a relay to the van battery and I had to finish the rest of the day with my van idling so I could work.

i have read another forum on here and it seems like it’s normal for everyone to have to charge their leisure battery every few nights?

I wasn’t told this when I bought the system, I’ve been using it for 8weeks with no issues so far other than it did this a few weeks back and I tightened up the battery connections and it seemed to resolve the issue.

Any help with what is happening would be appreciated as I don’t have a clue about battery’s, relays or alternators!

my colleague has also been having this same issue but after the alternator went he had it replaced and he’s had no issues since.

Its the same question that keeps getting asked in various forms.

 

If you do a search for 'split charge relay' there are dozens of threads with info for you to look at.

 

Here's just one example

If you don't do enough mileage @Sam Hodgson(or engine running time stuck in traffic) then you are going to be taking more out of your leisure battery than you are returning. That 'glass of water' is eventually going to become empty.

 

I personally can't see how a leisure battery is fully charged using a SCR or a VSR only. This is probably why, as an industry, we have been labelled as battery abusers. We also have so many windies with battery longevity problems, all because we, as an industry, don't look after our batteries the way we should.

 

We've tried SCR charging only and it doesn't work. When son in law worked for us he had a 20 mile round trip to work and then another 5 on the round. He used his van for personal use as well which also added charge to the battery. His battery went flat often and his day was cut short as he couldn't work.

Its a big risk running your vans engine whilst you are cleaning windows. Its also illegal to let your van's engine idle in the street unattended. The risk you take of someone stealing your van and kit isn't worth the risk of earning a few quid imho.

 

Yes, we have been in the predicament where a battery failed half way through a big job miles from base. We had to run the engine to finish the job, but one of us had to sit in the van.

 

Now if you have one of these new battery to battery chargers that use fancy charging algorithms then this could be different story if you do more mileage. I haven't got one or had personal experience with anyone using one. I've never bothered as I don't believe we do enough mileage to fully recharge our batteries, even with these sophisticated charging patterns.

I had a Grippatank system fitted in March they said the SCR should happily charge the battery and i haven't yet bench charged it, it is a Numax 115 ,after driving home after a busy day at work and letting it rest for four hours or so it is usually around the 12.6v. mark. I also use it privately and it will average around 150 miles per week, I note this time of year they can take a hammering and I let the engine run when possible (lunchtime etc)..it is located in a Peugeot Partner and is a bit tricky to get at so it's made me a bit lazy, it got me thinking this morning after a cold night and after disconnecting my oil filled radiator in the van, I could have also charged the battery.

Also I think Spruce said a bit back that you would have to travel 750 kilometres to recharge a dead battery, I would disagree, after a recent return trip to Devon and 600 miles it was showing 12.9v (I believe a full charge is 13.2).

What I now intend doing as an experiment is carry on doing what I am and see how long I can get out of it if I get two years out of it happy days, if it dies on me next week I'll have to up my game and bench charge every couple of days and stop being a battery abuser!

12.6 is nearly 50% depleted so I would guess your battery is constantly hovering between 50% or so, And 12.9 ain't fully charged so I would be inclined to agree with Spruce as it would surely take that extra mileage to reach a full charge.

Don’t forget batteries work under load so reading off 12.9 is pretty much fully charged

This is what I picked up from a RV magazine.

 

In my experience I once did a long trip from the North East to the south coast. My leisure battery was at around 75% charged when I started off. After 250 miles (5 hours travelling) the vans alternator was still charging the battery by just over an amp. It was only on the way home where the amp meter gauge was flickering between 0 and 0.2 amps input into the battery. At this point I called it fully charged; about 350 miles on the road, or around 9 hours including stop start London traffic on the M25.
