Q: Can this test for a battery drain as well as current battery output?

The meter performs the following primary tests: 1.System voltage: 12 Volts; 2.Test Results: Good, Recharge or Replace; 3.Capacity - Cold Cranking Amps (CCA); 4.Internal resistance value (mΩ); 5.Life in percentage (%); 6.Cranking system testing; 7.Charging system testing; 8.Voltage test in waveform; and 9.Record and re-play battery data. I've used it in several vehicles and on batteries to determine the status, and so far it has performed very well for me. I think the first seven points above will meet your need, although if the charging system fails, I don't think it will tell you exactly which component is causing the trouble. Hope this helps.

Q: Deep cycle marine batteries?

yes, it can work with Deep cycle marine batteries

Q: Manual also comes in Spanish ????

The manual that comes with it is USELESS; it is super-tiny; never seen anything like it ever before. It is about 2" square (that's an estimate, it is in my vehicle right now). I have 20/20 vision and I have to strain my eyes when I try to read it. It's pathetic. Doesn't matter this piece of crap gives inconsistent results anyway. REPLACE, GOOD-RECHARGE, GOOD, etc... randomly shows that any battery's health is anywhere from 20% to 100%. One a brand new battery in a friend's new car (purchased 3 weeks ago), it shows the battery health as 24% and says REPLACE. On my battery, it has been all over the place. On my neighbor's car with a bad battery that won't charge but will allow you to turn on the parking lights, this thing says the battery health is 95% and "GOOD BATTERY". Yeah, this thing is going back.

Q: do you tell unit battery rated cca and it tells you when battery at end of life?

You enter your battery"s claimed CCA, the unit performs a measurement on that data and gives you the amount of CCA the battery can provide. As the value goes down from the rated CCA, you have to make the determination as to how much life the battery has remaining.

A necessity to have

This item is great. Working on the several pieces of farm equipment we have, being able to check the life of your batteries is a necessity. Being able to see the voltage and test cold crank amps it perfect. Would definitely recommend.

Lets you know your car batterys health

This has saved me some money. It lets me test the battery to determine if I need a new one or just need to charge the existing one. When I am recharging it lets me know how far along I am and if it has fully charged yet. A good tool to have in your tool box. A good value.
