According to the NCC verified leisure battery report this battery is a class c and is good for 70 discharge and recharge cycles. And they aren't even full discharge cycles - only to 50% DOD (depth of discharge)

Its not a quality battery and in my opinion totally not suitable for window cleaning. That's why you are getting so many failures. Tell P/F to send out a quality battery.

If this is accurate then i can't understand why for the last 4 years we have had literally 0 issues with this battery.  I've also spoke to PureFreedoms managing director in depth about this battery and he said they have tested and used about 5 different batteries over the years and this has proved to be the best for them with the least amount of returns and complaints.

If you know the MD at PF then you know he has a good general knowledge of most things i've spoken to him about a dozen times and half the things he talks about goes straight over my head, he gets too technical at times!  Some companies the office staff are just air heads!!!

I will second the above , I used to use those batteries in 85 amp size , I was only paying about £50 a pop so that’s the sign that they are not the best out there .

That battery that is in current use , is it running 2 controllers and 2 pumps all the time ?
Do you have power reels ?

I’m still going with a cheap battery that has been used beyond safe discharge levels !

I will check the details you ask for in a mo , the battery has been at rest over night so I can guarantee that it will be around the 13.2 mark

The battery in use, is currently only running 1 pump and 1 controller, no electric reel either.  If anything the battery is overkill for its use.

OK so just got those figures you wanted , I am using a Numax XV31MF 105 amp and am charging with a £40 Halfords Advanced fully automatic charger .

Battery charged and rested ......13.1V
Charger at full supply....................14.7V
Charger on maintain......................13.7V

See now that voltage reading is impressive!  If my battery could read those levels it would proably last 3 days without needing a charge.

Out of curiosity can i assume you were checking the voltage reading from battery terminals rather than the controller.  I've noticed that there is often volt drop between the controller and the battery of about 0.3 or sometimes higher.

I can only quote what the NCC themselves say regarding their testing process. I can only hope as a consumer that their performance findings and ratings aren't biased.

With modern leisure vehicles featuring more technology and electrical appliances than ever before, buying an NCC Verified Leisure Battery gives consumers confidence that the battery they purchase for use is fit for purpose and will perform as advertised. Also, the NCC is encouraging its leisure vehicle member manufacturers to fit NCC verified leisure batteries.

Battery verification comes via a comprehensive, industry leading, testing process conducted by suitably certified and audited test houses. Batteries will be verified and labelled accordingly, into three categories: A, B and C, depending on their capacity and intended purpose:

• Category A is for batteries with a higher storage capacity for people who frequently use their touring caravan or motorhome away from an electrical hook-up:

• Category B batteries are aimed at those who frequently use sites with hook-up facilities, but require a greater battery capacity to operate devices such as motor movers:

• Category C batteries are for users that require a lower capacity battery to cover basic operation of their habitation equipment for short periods away from an electrical hook-up:

They say that most manufacturers have signed up to this concept. So the manufacturers of Platinum Batteries haven't challenged the charging cycle performance of that 'model' of battery.

There are a couple of battery manufacturers that don't appear on this list - I presume that its because they haven't signed up to having their battery performance rated.

A few years back numerous windies were recommending the Halford's supplied Leisure battery made by Yuasa as a good buy. When then started hearing more and more complaints of batteries not lasting. There wasn't an answer to this until the NCC Verified Leisure Battery testing provided the answer.

All at terminals with a stand-alone power analyser, as you can see here the charger isn’t plugged in

what split charge relay are you using? if you are not using one then you should be.

could be a long list of things, you are the best person to diagnose as you are there, check and re check everything, could even be a corroded fuse or your calibration settings too high so the pumps are drawing a lot of power

Not using Split charge relay and happy with our system without one for now.  What should Calibration settings be on?  Standard Pure Freedom Controller.

Thanks

you should be using one, fit a split charging relay controller, very easy to install,

calibration varies from controller to controller, you can set the calibration by using the auto cal feature in the controller, or set it yourself it is very easy to do

[Simon Trapani]

But I think you have to remember to turn those controller ones off when you finish work?

I'd rather have a fully automatic battery to battery charger or scr to help top up.

Just my two pennies worth.

no you can leave them on or turn them off makes no difference, they are a fully automatic voltage sensing split charge relay, I have them in 5 out of 7 of my vans(2 have smart alternators so use b2b chargers) and I never have to recharge the batterys

for the cost which is only slightly more than a normal flow controller they are well worth it, battery to battery chargers are much higher cost

[Simon Trapani]

The Spring one I had some years back (v7 I think) you had to hold the enter button after use to put it in charge mode if memory serves me right? And leaving the display flashing ‘CHG’ all night whilst not charging is surely a drain even if a small one. So they’re not fully automatic like a battery to battery or scr. And I thought they had a very low charge rate. They were only on the standard skinny little cables that came  with the controller. Maybe the newer ones are better but I didn’t think much of it personally.

This is one of the reasons I rarely post on forums now, there is always someone who has little or no experience who knows it all,  I wasn’t trying to convince you Simon I was trying to help the op when I shouldn’t have bothered as there is not even a thank you. You can tell this forum is full of window cleaners

Scrimble thank you for your input on split relay charge.  I've been using leisure battery only and charging now for 4 years and its worked just fine for us, other than these recent issues so too be honest i dont want to change over.  New battery has now been sent out i will be testing it on monday!

[NWH]

I have changed everything except the charger, and the wiring.  Im losing patience now, its cost my worker 2 days income which could of easily been avoided if i just went chicken oriental and got the whole lot done ages ago.  Downtime can be more costly then replacement parts!

Spot on there much more costly to be off rather than to have paid 100quid or so for a pump etc.
