Does anyone have any actual experience of these batteries please ?

Yes, I have virtual identical batteries made by Leoch that I purchased from Alpha batteries. I recommend both the battery and the supplier. My 3 * 130Ah versions have been in-use for 3 years and still giving a similar capacity as when I purchased. I would always use a Victron battery protect device such as https://www.victronenergy.com/battery_protect/battery-protect . I expect to get 8 years minimum out of these batteries!

I have no idea of the history of my VB or LB so might need to change them at some point, what are the advantages? and do they need any special charging?

Around 5 times more charge/discharge cycles, 200 Vs 1200. Approx
Will accept bulk charge current for longer giving faster charging times.
Reaches it's full capacity with less absorption/CV stage charging.
Can sit at partial state of charge without sulfating at approximately above 50% SOC. This means they last longer and give higher power for longer.
Higher charge efficiency (storing and releasing the charge that's been put in) 95% Vs 85% approx.
Higher tolerance to deep discharging. Lead acid typically discharge down 50% whereas a LC could be discharged down 90% for the same level of ageing. This means that a carbon battery has nearly twice as much useable Ah capacity in typical long term use.

Oh, and they plug and play and suit existing chargers.👍
 
Thanks, I'll try to bear that in mind if and when we need to replace them.

I assume as you haven't mentioned it that they are ok as a VB as well.
 
As far as I can recall Kev there is no info about the maximum permissible cranking amps of the usual suspects ie the Leoch AGM and Gel LC batteries so possibly not suitable as a cab batt?
Carbon battery tech is advancing fast and there's recently been several manufacturers releasing Stop-Start EFB batteries with Carbon technology, at present they don't seem to be full blown LC batteries, more a sort of half way house but they are relatively cheap and cost little more than standard lead acid.

I got one for a friend about a year ago Wooie but it had a special offer on it, at the time was cheapest 120ah Alpha had and money was important for them. They don’t use a lot of power and this battery is serving them well

Edited as predictive text thought you were in Star Wars :)
 
Ultimately a lot will depend on how you use the battery and more importantly how you maintain it. If you can get it fully charged back up soon after any discharge and keep it topped up then it'll last way longer than having it hanging around in a partially discharged state, as it's this that typically knackers LA batteries in the camping environment.
If you're a regular cycler ie actually discharging the battery and then re-charging then the above wont stop the battery from cycle related ageing. BTW sitting on site using the 12V system while on EHU doesn't count as cycling because the 12V power being used is supplied by the battery charger and not the battery, It's only when you draw loads that are higher than the capacity of your charger that actually drain the battery, ie inverter loads (which you probably wouldn't be doing as you're on EHU!)
 
Be interesting to see how many seasons he/she gets from it.
Also Jamist's use/charge regime as they've already been going 3 yrs and still doing well apparently. 🤞
