Wrong batteries??

[bigtwin]

( fully charge it up and then take it to a place that sells battery's and they will load test it for you ( tells you if it's good or scrap )

What discharge rate would the tester use; C5, C20, or something else?

A leisure battery should be tested at the C20 rate.
Anywhere you take a battery to be tested you can be fairly certain they will give it a CCA test which is a starter battery test, which is meaningless for a leisure battery.

Agreed.

Is this a mains-powered charger?

CTEK D250 Dual - Combined MPPT Solar Controller and B2B

 

[TheLifeofBrian]

I have 2x gel leisure batteries , no solar and can go at least 1 week with no Hooke up

What ah are they and do you use tv, heating etc or just lights?

It is only mains powered via the EBL29 I believe. The CTEK controllers are just to control inputs (solar, alt & mains) and output to the batteries I think.

95 ah each , watch tv on fire stick and lights are led , heating truma gas

Some information for you about these batteries. There is also a cheaper version (LDC2) just been released too.

Sorry - not sure what happened to the last post!!
It should have said:
I've just spoken to an advisor at Alpha batteries and he has recommended Lead Carbon Gel batteries.

12V 110AH Expedition Plus Lead Carbon Gel Ultra Deep Cycle Battery (EXP12-110C) - Alpha Batteries

Ultra Deep Cycle Lead Carbon GEL Battery

www.alpha-batteries.co.uk

Apparently my EBL29 doesn't have an AGM setting, only wet or Gel - even though the manual says it can be used for them - apparently it doesn't put out the 14.7v they need to fully charge & will only get to 60% charge.
That perhaps explains why they have died..
These Carbon Gels can be used down to 20% charge and 15000 cycles so sound pretty good - has anyone had any experience with them?
Quite a good price at £190 for 110ah I think - minus a bit of club discount

cheers
Chris

I think that Hoovie is your man for info on lead carbons.

whoops forgot to add one more data sheet.

Have you any experience with the lead carbon gels? Alpha have recommended them to me rather than lead carbon AGM.

No I do not ! I am of the view Alpha would recommend a battery to a customer that was more in the interests of Alpha than the customer. Saying that, this battery has a decent weight and is cheaper than the Leoch. (Only by a few £'s) However, if you look at the cycle performance (on the product data sheet), the Leoch is 2-3 times better than the Expedition.

I am more interested in the fact that it is Gel rather than AGM. They told me I haven't got enough voltage (14.7) needed for AGM & I have 14.4 - doesn't seem a big difference?
I understand Gel's can stand a lower discharge & these carbon Gels are supposed to give 1500 cycles - slightly better than the Leoch 1300.

The Leoch require a charging voltage of 14.4 - 14.6V according to their data sheet

The Gels data sheet does state around 1500 cycles at 50% DOD but goes no further. The leoch states around 2000 cycles when 70% discharged. I believe charging at the correct voltage is essential and if you only have 14,4 V from your charger it does meet the charging requirement set by Leoch. If you have solar and user settings on your solar regulator you could set this to give no more than 14.6 V. Its your choice and you should choose the battery you think will be best for your set up and usage.

Had duracell AGMs for 6 +years still performing well. Think its that a lot of chargers are not set to charge AGMs ours is and so is our solar regulator.

 

[steve69]

Storage capacity is down....batteries failing.

Just yesterday I charged an old 100ah battery showing 3v.
Once fully charged (13.6v) and rested for a couple of hours (12.6v) the voltage was good but storage capacity was down to 45%.....that's a capacity of just 45amps instead of 100amps for a healthy battery.

How did you measure that?

Ultra Deep Cycle Lead Carbon GEL Battery

www.alpha-batteries.co.uk

I've had three of those fitted for two years, no issues to report, one thing to note is the AGM batteries state charging from 0c whereas the gels state charging from -20c so if cold weather charging is an issue you may be better off with the gels, on the other hand the agm's charge a bit faster. I've had both types but only had the agm for a year before I sold the van so can only say it worked okay but I did have an agm profile on the B2B.

 

[nabsim]

So given they are probably duff what in a Motorhome could knacker two batteries so quickly given minimum cycles and charger seems to be working fine . Could one duff battery damage another ?

Taking too much out of them. I killed 3 Bosch/Varta powerframes in 12 months by taking them too low. Was in the van full time in Winter in the U.K. and didn’t have a generator back then. Knowing what I do now it was always going to end badly as I use 65ah per 24 hours

There's a bit more to it than just the voltage. AGM and Gel batteries are 'recombination' batteries, which require a timed extended absorption stage. This is often several hours - 8 or 16 hours for example. With a standard lead-acid, the absorption stage ends as soon as the amps falls below the preset minimum 'tail current'. For AGM and Gel, the absorption stage is extended by a timer for several hours. During this time any hydrogen and oxygen gas produced during charging is 'recombined' back into water (H2O).

I think this is more relevant to mains charging, because the power input is long enough to do this. Solar and B2B are unlikely to provide that extended time stage reliably.

The difference between the lead-acid and Gel settings on the EBL29 is the extended timed absorption stage, the voltages are exactly the same (14.4V).

This may be the information you have seen on a specific AGM battery and assumed, it applies to all AGM batteries. It does not! and if you look at the link below you will see this AGM can be charged 20 Deg below C and operates from minus 40 deg to plus 60 deg.
I suspect the Leoch is more or less the same.

You are correct ! I would still choose the Leoch as the temperature inside my motorhome never falls below Zero degrees when its in use and only for a few hours a day when not in use.

I don’t know if this will help anyone but just in case i'll post it anyway, I'm currently at the rally at woodside field, I have 3 lead carbon gel batteries total 330 ahs, which were at 100% when I arrived yesterday and 250 w solar, by 09:00 this morning the batteries had dropped to 95% running my cpap machine, watching some tv etc. By 10:30 this morning they had gone up to 96% and the solar has gone from bulk charge to absorbtion, so that might give an indication of how quickly they charge up. It is currently quite sunny here and i'm getting between 7.5 and 8.5 amps from the panels.

Hi all,
after nearly a year if owning my 'new to me' Motorhome I find I have the wrong leisure batteries fitted!
We are away in it at the moment and a couple of nights after being 'off grid' I've found the control panel flashing red & had to turn everything off. That included using TV for an hour, lights & leaving heating (gas) running all night. They recovered after 30 mins or so (12 volts) & after the solar panel kicked in when the sun came up they were soon back up to 14 volts.??
After asking an expert (and realising the obvious!) It turns out that if your batteries say 'stop/start' on them they aren't really leisure batteries but normal car batteries this is quite annoying after buying the Moho from a dealer!
Can anyone recommend somewhere to get a proper pair from? AGM preferably - and does anyone want to buy a car battery or 2

Cheers Chris

Maybe lifepo4 battery is better

 

[PhilandMena]

The Leoch Pure Lead Carbon are very good AGM batteries and will accept a lead acid charging profile. Lifepo4 is the dogs but you need to make sure your charging set up is suitable for these type's of batteries including Solar and Alternator set up.
Any of the big battery distributors will meet your need and some may offer a small discount for multiple battery orders.
