Hi Loanragie, and yes they are a game changer.
I bought a number of them at the beginning of the year for testing and I am very impressed.
One of their biggest advantages is that they can be left in any state of charge indefinitely and with no detrimental effect on the battery.
They are actually delivered with a sticker on them indicating when the battery was last charged, and some of the batteries I bought were last charged nearly 12 months earlier.
This one feature alone makes Lead Crystal batteries ideal for RV use, particularly for use as house batteries in caravans and camper trailers, that are left unused for long periods of time, between trips.
They are also “UNDER-RATED”, meaning they are actually rated at a lower Ah than they can provide.
Lead Acid deep cycle batteries have their Ah rated by testing at C20 loads, where as a Lead Crystal battery's marked Ah is rated using C10 loads. When tested using C20 loads, they are much better than equivalent lead acid batteries.
Another big advantage is that they can be CONTINUALLY discharge to 0% SoC ( 10.5v ) many hundreds of times.
I have been cycling a number of these batteries down to 0% SoC and then charging them with different recharge voltages and they can be easily fully recharged with voltages as low as 13.6v. I have not bothered charging them with lower voltages as yet.
Here are some examples of Ah ratings.
6-CNFJ-100, their standard capacity 100Ah ( C10 rate ) battery has a C20 rating of 110Ah.
Recommended Retail price of $550
6-EVFJ-100, their HIGH capacity 100Ah ( C3 rate ) battery has a C20 rating of 124Ah.
Recommended Retail price of $695.
While these batteries can be used in many Land Rover applications, I now have a 65Ah Lead Crystal battery in my L322 RR, but there is no suitable sizes for under bonnet use in a D3 or D4.
BTW, I will soon be selling these batteries.
