For those who’ve followed my blog from the start, you’ll know that I’ve had a bank of Elecsol batteries, a bank of unbranded lead acid batteries, a bank of Numax batteries and I have successfully killed them all! The Numax faired the worst, they starting deteriorating within 6 weeks of installation, and the setup was darned good. The Elecsols, although I would never touch one again with a bargepole for several reasons, have probably faired the best til now. But compared with their stated abilities, they faired very poorly.
Over the last few years I’ve learned quite a lot about batteries, their applications, appropriate usage, care and maintenance. What I have learned is quite simple:
You can kill any battery no matter what it is if you don’t care for it.
Even average batteries can last you years if you care for them properly.
Now, although I know how to care for mine, the life they lead with me is slightly unforgiving at best, and very demanding at worst. As I said once before I don’t blame Numax for making bad batteries, I blame Adverc for incorrectly recommending the use of Numax’s. So I have spent time recently in Llandulas in North Wales, enjoying Wales and thinking about what to do.
Here’s a recent sunset I observed from where I’m parked.
So, after a lot of thought and research I have chosen my next batteries, and as luck would have it Tayna are only about 2 miles away and can supply them in 2 days. They are going to be…dun dun dunnnn…
I present to you, Trojan, J185 H-AC 12v, true deep cycle, monoblock, open lead acid battery.
Check this baby out. At the 20 hour rate it delivers 225 ahrs. It weighs in at a colossal 58 kilos and is about a third of a metre high.
Now, as we know batteries shouldn’t really be discharged below 50% of their capacity. However as this is just a solid hunk of well built lead, you can discharge these down to 20% of their capacity. Of course it will shorten it’s lifespan, but even doing this it will still last longer than most batteries on the market. I do intend to use them as frequently as possible to the 50% DOD state though.
I got what I think is a great price: £225 each, so I bought two. This price is about equivalent to the six Numax’s I had and also to the combined cost of the 5 Elecsols. The most difficult thing has been in getting rid of other stuff so that I can carry the batteries’ weight. I’ve emailed Trojan’s tech support many times already getting information from them that I needed and they have been superb. I’m looking forward to good things so watch this space!
