Trojan t-1275 vs Signature series J150 RE
Before winter, I need to get a dedicated flooded house battery, my Northstar AGM-27 has been working hard as both house and engine battery for the last 4 months, and I want to return it to engine star...
Forum Discussion
Ok we have two batteries, same size same casing, one has different handle design and says it weighs two more pounds than the other.
We have come to equate all things being equal, the heavier battery is better.
Then we have trojan's technical respondent saying both batteries are exactly the same internally. No difference, and will not touch the RE question regarding a lower recommended absorption voltage, except perhaps if I call the number which was emailed back to me when I responded with displeasure at their intitial response.
Well their own spec sheets have a 2 Lb difference, heavier for the J150.
Are we just to disregard this? Perhaps we should all weigh our batteries rather than believe the spec sheets. If the spec sheets are wrong, then what if the effing point?
Marketing is really pissing me off, and not just regarding batteries.
So then we get Trojan's signature series, their signature J150 that has a Green RE on the end, and an absorption voltage recommendation well outside what we've come to expect from Trojan, much lower.
MOre meaningless marketing to appeal to the renewable energy crowd? It appears so. These batteries aint going into a golf cart, but into a storage shed to be fed by renewables, Quick order up a sticker to satisfy this Man, charge him double for it!!!!!!
Is that where things stand? Can there be no further improvement in plate paste, separators or any other aspect of Lead Acid deep cycle batteries?
Perhap I was hoping they came up with a battery that was perfectly happy , or perhaps less unhappy at being charged slower via solar and perhaps not to 100% every recharge cycle. Is it really too much to ponder this possibility?
But Old Mex says nothing has changed in 30 years, and throws in a few insults of his own toward anybody who might ponder whether it is possible things just might have since he had an insider's scoop and personally affronted the paisley and neon tie crowd as often as possible, if we believe his own rants.
I mean the lead acid battery makers have to be shaking at the thought of Lithium taking over. It is coming. Lead acid battery's days are numbered. Would they not be interested in trying to negate some of the negatives of Lead Acid and try to hold onto their market share, or is it such a lost cause they they just decide to give the marketing department more leeway to basically just lie. Cash in and check out and keep people snorting the Kool aid, one nostril at a time with their useless PDF sheets rolled up into a straw?
I was hoping for discussion, not just a crusty curmudgeon's exasperated harrumph.
Whatever battery I do end up with will have its specific gravity maxed out as often as possible, whether I can get inside its cells to read it or not.
I've got all the tools to do so, and no blind faith in blinking green lights, or marketing, or my Fellow human.
Plenty of rage though.
I appreciate those of you experimenting with the telecom batteries and sharing your experiences. I cannot go such a route. Mine is just a DIY class B. Space is limited. I will be going to great lengths to get a T-1275 battery to actually fit. It would be much easier and cheaper to just get another group31 knowing full well it is a quasi deep cycle battery, but that is a compromise I am not willing to make. Been there, done that, nothing more to learn there.
I want a flooded deep cycle battery. I have my Learner AGM battery already, and I like it. but i am not going to have a bank of greedy AGMS that are unhappy with a peasley 200 watts of solar day after day when discharged to 50%.
More capacity is not happening, more solar is not happening.
The Screwy31 was a dual purpose battery with a deep cycle label and a bunch of flowery marketing. But it also dealt with huge recharging currents. I will be asking a T-1275 to deal with those same huge recharging currents, upto a 50% rate, perhaps more, if it decides to accept it.
Will it protest more than the screwy31 did at those same high recharge rates?
It comes down to that.
