I'm just getting into this..so pls b patient..I have been reading for weeks, and thaught I had it ,Now I'm lost again..We(Wife and I,and boys when on leave) Like to go camping,fishing etc..I made a bait bucket wth a pump. 1.8a pump. I have two 1000cca bat's. I know cca dont count for what I want ..can not find ah for them. any way...I want to set bait bucket up to solar..Run 24hr.while @ lake 4 to 5 days.If I figured right.. It would have to be a large panel to keep full charge..I was gonna use 12v 1156 led (say 4) for night light around camp. 3 to 4 hours on 1 bat..pls help.. now I'm really frustraded.

An automotive starting battery (that's the CCA spec) will die very quickly when used in deep cycle use. Just so you know.
So the pump draws nearly 2 amps. With a typical 90AH deep cycle battery, you could run it for 45 hours before the battery reaches 50% and needs recharge.
Running 4 LED lights, it could be weeks before the battery is at 50%. For a weekend, 4 LED lights will last till you get home to recharge.
You need a charger that can recharge deep cycle batteries, which need a couple hours extra charge compared to a car battery.Powerfab top of pole PV mount (2) | Listeroid 6/1 w/st5 gen head | XW6048 inverter/chgr | Iota 48V/15A charger | Morningstar 60A MPPT | 48V, 800A NiFe Battery (in series)| 15, Evergreen 205w "12V" PV array on pole | Midnight ePanel | Grundfos 10 SO5-9 with 3 wire Franklin Electric motor (1/2hp 240V 1ph ) on a timer for 3 hr noontime run - Runs off PV ||

OK let's start with the CCA rating you mentioned. CCA = Cold Cranking Amps. This indicates it is a starting battery, not a deep cycle battery. All CCA means if the battery is fully charged, at 0 degrees F, it can deliver its rated amperage for for 30 seconds at 7.2 volts. It is just an indication of how the battery might work to turn a engine over and nothing else. It has nothing to do with the Amp Hour capacity.
Starting batteries are made differently than deep cycle batteries. There plates are much thinner, spongy like, and many of them. This allows them to deliver very high quick burst of current, and a very high recharge rate. Perfect for starting an engine, but worthless for deep cycle applications. the reason is the plate design. thin spongy plates when pressed into deep cycle service erode away very quickly and/or become sulphate easily.
Deep cycle batteries on the other hand have fewer but much thicker and heavier plates designed to give a slow constant current for a long period of time. So if you see a battery with a CCA or MCA rating, you do not want it.
So I am going to get right to it. I am not going to bother with all the math, but rather just tell you what you need. You need a good quality 12 volt, 200 AH AGM battery like a Trojan 8D-AGM 12V and a good quality 3 stage 20 amp AC powered battery charger like this one

Thx ya'll. Thats what I needed is to get an actual opinion... I did do the math right..Just couln't believe that tsumani pump would take that mutch to run...So I could get away wth these batteries to use led's next week, just not run my pump...I try to fgure something else for that...The batteries are in garage going to waste anyway..there alliance AE1131XMF, from my old semitruck..Comment

Thx Mike,SunkingComment

ok ,, I think I will just run pump through the hotest part of day like, 4hrs a day then run my aereator the rest of the time,it runs on 2d(not in series) so its 1.5v,I will get a volt dropper and hook both up to 12v battery.Now I will only use 8amps a day on pump,and I have no idea about aereator.cannot find any draw amount anywhere..but then I could get a small panel to trickle charge..Comment

Thx for everyones help, will be getting a couple deep cell...Comment

This pump. Does it use 1.8 amp at 115 volts AC or 12 volts DC? If it is DC, then it would seem that you could use the batteries you have. If what I have read is correct, a car battery will recover over and over if you use no more than 1/3 its rated capacity.
Doing the math with my trusty solar powered calculator, I see that five days at 24 hours a day would give you 120 hours. Multiply that by 1.8 amps and you have 216 amp/hours or much less than 1/3 of 1,000 amps or 2,000 if yours are connected in parallel. the AG whatever battery is nice but at $585, it doesn't leave much for buying bait. It would be cheaper to go to a a wrecker service and buy the battery out of the latest wreck.
What is a bait bucket anyway?
A cheap battery I bought from Autozone, and installed in my daughter's car the day before she wrecked it, had a government rating of 95. This means, according to Wikipedia, that it will put out 25 amps at 12.6 volts or 497 watts for 95 minutes. This would allow me to use about 165 watts. Two in parallel would be about all that's needed for the bait bucket.Comment

Thx,jockellis.The pump uses 1.8a 12dc.I appreciate your reply.A bait bucket keeps minnows and perch alive it just recirculates water , puts oxygen in water.I made one out of a igloo cooler with a 12v live well pump. People use these on thier boats. I do not have a boat so I shore fish..built a wagon to hold all my stuff.Wanted to keep my bats charge on longer trips..Comment
