How often Should you charge batterys I had to charge mine every night after 4weeks old from ionics. now have new one NOT FROM IONICS.

[AS Window Cleaning]

if you do a search on batteries should find a few on this subject.

we personal charge our 110 amp every 2 weeks.... for 3 days 2 operators on 2 pumps.

others charge daily. I think we got lucky with batteries, does seem to be some dodgy ones also. also depends on length of hose, micro/mini bore, pump speed settings, number of operators.......

Hi

This has to be a difficult question to answer, hence the lack of replies.

I would love to know what pumps Atilla the ..... is using as he must have a pump with an exteremely low energy draw.

Our Shurflo 5l per minute pumps each draw between 2.5 and 4.4 amp depending on the Varistream Digital speed setting. (Speed setting 4 = 2.5amp, speed setting 5 = 3.4 amp and speed setting 6 = 4.4amp. These readings were taken with the pump pushing water through 100m of 8mm minibore hose with all but 5m still coiled on the hosereel and connected to the brush with 2 only 2mm pencil jets. The 85amph leisure battery in this van is new and at the point of test was 12.5v or fractionally over 75% charged. When the engine was started the alternator was supplying a charge to the battery of 3.1amps via a split charge relay - van = Ford Transit Connect. With the engine off and battery coupled to a 10 amp Numax intelligent leisure battery charger for motor homes it charged battery at 7.5amps).

So if I chose to run at setting 4 which is approx 1.5 litres of water per minute and the pump does 4 hours work per day, then the battery would need to provide the pump with 10 amp. So with Atilla's battery his charge will be down to 100 amps at the end of the day provided he started with a fully charged battery.

Now whether that means that a 110 amp battery will last 11 working days before its fully discharged I can't say for sure, but in this example you would be well safe charging it once per week, although I would still prefer to charge it every few days.

This was just a quick test to make sure the Volt/amp guage I bought works. I will install it permanently in my van (Citroen Relay Hdi) in the near future to monitor what happens to my leisure battery when its being charged via a split charge relay, what amps the battery will accept and what the amp draw is with 2 identical pumps working at the same time.

We may also be able to get some feed back over time with regard to battery performance in conjunction with ambient temperature and age.

Should be an interesting exercise.

Split relay.

That's all I'm saying.

i charge my pure freedom trolley battery every night.nearly 2 years old.never misses a beat.

Your replies are always knowledgeable and concise spruce. 

For your info, and as i seem to get extra long life compared to many, this is what I have.

110 amp leisure battery
2 varistreams, set at speed 3/4 temp depending, and presure 6.
2 Flojet 6.3 litre per minute 9 amp max pumps, 100 psi.
60 meter approx of minibore (whatever the 8mm stuff is).
2 operators working 7 hours a day for 3 days a week, all low level 2 storey stuff.
Pure water

Im wondering whether my charger helps, its a Ring Intelligent charger, i only charge on 2amp (instead of up to the 8 i could) as apparently slower charger is better, i normally leave it over the weekend about 48 hours, its charged long before then and just cycles.

And, Yes, i wondered if would get less battery life when its colder, i imagine you would.  Esp as I have the back doors open when i work.  I used to have spare battery in van, but its now in the shed powering the static solenoid, so thats why i charge every 2 weeks, to be on the safe side.......

i have two vans one van lasts 2 weeks with no split relay ,the other 2/3 days both 110a i am trying to work out why the difference /either i have a gel battery and that lasts 5 times longer or that a shurflo pump uses a lot more power than a flowjet any ideas thanks

[pristine window cl]

thankyou everyone, maybe i should have mentioned that i use a thermopure but i do not run it every clean,
i work on my own with pump not to high,

Hi Atilla,
I understand that the slower you charge a leisure battery the better it is, so maybe this is a reason. I read somewhere that the intelligent chargers will get 25% more charge into a leisure battery than an ordinary charger will, so is this extra 25% in the 110amp statistics or should it be added on top of it?

It could also be the flojets don't use the same amperage as the Shurflos. Also the shorter hose length will further reduce energy needed to pump the water through it.

I've just noticed something else this evening. My son in law has the latest Varistream, new Numax battery and pump. This is the Varistream that shows one, two or three bars depending on the state of charge in the battery when you press the relevant button.

He has been away for the last two weeks so his van has been standing idle.
I thought I fully charged his battery just after he left so I was a little surprised it was only 75% charged last week when I tried my new gauge on it. So I left the charger on and fully charged it as I started to doubt whether I had charged it or not. Anyway, went out to the van this evening and put the charger back onto the battery and again it's only reading 75% charged.
If I disconnect the battery and reconnect it then it sounds as though a solenoid engages in the Varistream. There is also a spark when putting the battery terminal on.

I presume is that there is a flow of current through the Varistream that enables the voltmeter in the unit to operate. If this is the case then I will need to get a seperate on/off switch to totally isolate this unit when it's not being used as this will also add to his battery performing less efficiently.

Maybe I ought to email Williamsons pumps as they are sure to know.
