Lead Crystal Battery - Very Impressive

Post by Chris Skinner » 11 Sep 2013 20:42

After researching long and hard I bought myself a 100AH Lead Crystal Battery - actually wanted a 120AH but got this one at a real bargain price. What I have read on the internet and seen actual trials on YouTube seems almost too good to be true, so when I got the battery home I put it to the test. I made sure it was fully charged then I connected it to a 60 watt globe to see how long it would take to get to a state of 11volts under the said load of 5amps.
The result is astounding, see the graph below. A normal lead acid will not achieve this, and if you did push it for the same duration you would do permanent damage to the battery. The beauty of LeadCrystal is that it can be taken to a completely 'flat' state and recharged without any damage - it can cycle like this hundreds of times according to its specs.
Back to the graph - this shows that the battery pumped out over 100AH over the 25 hours, where you can only get around 60-70% of the AH out of a lead acid, and maybe 80% from a deepcycle without risking damage.
Speaks for itself in my view - the LC is more expensive but will last you 5 times the life with far better performance - output, quicker recharge etc....
Do yourself a favour and research this ... you wont buy another battery!

At BushPower they go for around R3000 I beleive.
You can also look on Deltec website for more info.

When you get some time look at this youtube video - http://www.youtube.com/watch?v=O45eLd5YotM

Got myself the 70 Ah (biggest one I could fit) Deltec Lead Crystal from Bush Power last month for R2k2 (inc. VAT).

I've just returned from a trip to Ponta Malongane where it ran my 50 liter National Luna fridge/freezer (2.5 A average current drainage) and a smallish LED camp light for more than a week with very little driving in between. There were some practical issues though:
  • The National Luna dual-battery monitor was convinced that the poor battery was being abused and screamed at me to do something about it right away. I had to turn this silly alarm off every single time the battery went below 11.4 V.
  • The fridge initially also turned itself off to try & save the battery even though the battery did ask to be saved. I worked around this issue by setting the cut-off voltage on the fridge to its minimum (9.5 V) and turning the battery alarm on the fridge off.

Any idea what temperatures these batteries can handle?
For those of us, like me, that have the second battery installed inside the engine bay.

Can one use this type of battery as a main, or only as 2nd?

Alex, hey handle high temperatures much better than deep-cycle batteries, and even slightly better than crank batteries.

Stefan, I am pretty sureyou can.
