Both are good, I use both, and both are premium over Wal - Mart cheapos. If I could walk ashore, I wouldn't care as much. Cars use a quick start and done – EV's drain them down way deeper, in some (too many ) cases too deep to recover. The company rules says safe discharge is just over half – for maximum life – every emergency has the possibility of deep use damage. To test this I fully charged a four battery pack, of two year apart age groups, one was maybe questionable but so what ??
We cruised fine for over two hours, the gauge did a nose dive and the breaker opened, oops !! Oldest battery smoking, others warm differently, a minute and some seconds to cool and off we went, for 50 yards then click. More wait, 50 yards, click, repeat about four times with shorter good times, then managed to paddle and drift to the dock. That was a fine day, zero wind, and just John Kohnen and I out for a Fern Ridge lake cruise. OK, now how many times did I hear some guy say, lets just add two more to my pair and save the bucks ?? One battery smoked, two should never be recovered -- well, one maybe – but not for me. Balanced pack, same age, new programmed charger, equal moderate discharge – or regret it when the weather turns sour, my opinion. I had a cow when it first happened, lost at sea came into my mind. A generator set – pretty useless immediately. Using the pack hard while charging is also a battery / warranty breaker, takes way too long, has the old smell and noise --- not a good idea for several obvious reasons.
New pack, after a good BREAKING IN PERIOD, did I say that loud enough – will cruise many hours depending on weather, load, hot rodding, and other issues, but no more "death dives" from the pack, and a useful reserve. Every boat has it's optimum speed, Exceeding that drains the pack in a nasty curve, avoid that or !!!
The best two in this test were still showing and testing OK / good, on the meter – I also chucked those -- how about you ??.
Just a note on packing in the amps, Cal
So deka are better than interstate? Think I have one around that says chrominum on it??
12v batteries I would need less of?? But would that cut down on my power and have to retwire the battery compartments?
I can check this out. What one of my suppliers does is sell the used or outdated batteries to big box outlets I can't name -- they are used over a couple years, then relabeled, recycled and tested to exceed the warranty, most likely ! -- with a few returns probable. After the warranty period they drop capacity more than fresh ones, so somewhat lower performance, faster voltage drop, for less bucks. I wouldn't do that, and of course they will say different but it is their product. I figure that amps are the energy output of the hay the horse (battery) eats, more is better but the horse needs to work hard, and have a long life or it is a waste of bucks.
If interstate does your batteries now, that's good, the Deka is a premium brand, usually last longer -- but that extra in service time is not for me to decide for you. Usually more lead gets more amps for longer time, and of course costs more up front for that. I can check Interstate numbers and get back to you on that exchange, with todays price and availability. I need to check tax stuff for Washington, and delivery in house or by post. Sealed batteries only, in most cases.
Lithium is a very expensive way to go, my 10 amp by 48 volt bike battery was expensive, and still weighed more than I had hoped for. Car batts may be different, but adding guesstimate of 25 to 40 % to a high quality sealed wet cell cost is a bunch. I have a listing for Toyota Prius replacement batteries, those might be a good way to build a pack. Probably better than original equipment, or why offer them??
I have super chargers for all types, with a new hot pack, you might want a better charge cycle program, or other latest battery saving pulse type. Sam's club may, or may not, have balanced packs or accept fast charge without reducing the service life. By the way, I did look there myself, to see what was available.
Thanks, Cal

I'm not in town now, but would be in the Seattle area
I think, if I remember right they are interstate u2200??????
I think they are about 8 years old. They still work but hard to get up some hills
They are in an 1981 ford escort...jet industries car. 108v pack I think
Guess lithium would be best but not sure of cost and then need bms and charger etc??
If I can find a cheaper alternative that's even better, some say SAMs club are the cheapest way
Thx
Where u located at?

I do sales for Both Deka, and Interstate, plus usually have some special deals on specific batteries as they are available. I can always beat the prices, but often I can find some that fit the use better, run times desired or more, using your input data.Simple replacement first off --- What size do you have, and how much have you been quoted for a pack where you are now ??Do you want more amps or maybe larger size, if you have space, or a simple replacement ?? I have slightly taller ones that have a common foot print, as good choices for you.Does brand make a difference, or is time the first line, like 3 to 4 years over 5 to 7 years, or longer, a choice of dollars over service time ??Where are you located for delivery purposes ?? I can ship all sizes by weight, only sealed batteries by common means.If you need a new frame or fully rewired with new terminals, that can happen, and makes shipping more cost efficient, as the batteries are secure in that frame for way easier packaging.With some data, we can find what fits best for the car, and your needs.
