My opel corsa utility 1.4 bakkie isnot starting. sounds like a flat battery but when I check my battery I get 12 volts

Test the battery for load not volts. Use a load tester. If it falls below 9volts under load replace battery. If the battery is older than 3 years old replace it. A bad battery will damage the alternator (full field condition).

Hard to turn over with battery key. seems to start easier with key. Also battery dies easily

Have your battery load tested with a carbon pile tester to see if it holds it's load replace if necessary

Turn on ac or defrost and it dies has a rough idle

With thanks to Gary T From TheStraightDope.

it looks like your battery is knackered. Test it by following Gary's procedures below or perhaps just buy a new one.

If it's a serviceable battery, remove the vent caps and test the specific gravity of the electrolyte fluid. A tester for this is pretty inexpensive ($5-10?). A difference of 30 points between any cells is suspect, a difference of 50 is bad (replace now). If there's not enough liquid in the cells to fill the tester, bring them up to their full mark with clean water and wait a day or two for it to mix in. If the liquid is below the metal plates inside, buy a new battery now.

Other tests require pricier equipment or trickier procedures. A load test can be done with a load tester, or by disabling something to prevent the engine starting and then cranking it for 10 seconds, in either case reading the battery voltage at the point it's been under load for 10 seconds. Starting with a fully charged battery (12.6 v), it should read at least 9.8 v for the load test - but if it's close to that, it's weak. Really good batteries read over 11 v.

What is a load tester for a batterie

A load tester is typically a resistance pack with an amp gauge to see how the battery deals with current draw. most automotive parts stores have one to bench test car/motorcycle batteries, which they do at no charge (pardon the pun).

Batteries can have a "surface charge"(voltage) which will supply low current at the specified voltage from a battery with bad cells, but when a real operating load, such as for an electric motor, the charge drops to zip..

If the charger is putting out voltage to the battery while it's plugged in then it would definitely be a battery issue, generally the charging system for electric wheel-chairs has regulatory circuits to prevent over charging so having one plugged in when not in use typically doesn't cause issues.

No-start. battery good, starter good

did you test load your battery (vat40 or carbon load tester) seems you may have a bad cell and is droping your voltage or a bad ground cable can also cause it, check both and dont forget your starter relay this one can be jump to test circuit. good luck

Dosnt keep a charge

Its ether the battery or the alternator. The best way to check it is with a load tester. To check it hook the tester to your battery with your car running, red to positive (+) black to negative (-) if the alt. Is good it should read around 13.6 volts to check your battery shut off your car and toggle the load test switch hold for a 10caribbean count the meter on the tester will tell you if its good. If you don't have one or can't get one most parts stores. Will do it for free. If both check out good you have a dead short somewhere. In that case you just have to track it down. But start with battery or alt.

My 1997 cadillac eldorado has a hard time starting after sitting, but runs fine once started

Check the battery condition. This can easily be done with a battery tester. It may be under load and the batter has a bad cell or a cell that is going. Also the starter may be overloading the system. Also an easy test with a load tester.

Can I use a standard hand held battery tester to check the batteries and charging system in my travel trailer. The tester is a I35 AMP Battery Load Tester.

You can teat the battery with this, but you need a volt meter to test the charging system. Your battery should have about 13.5 volts when the ehicle is running.

Pontiac G5 only starts when jumped. Battery tested out fine, Alternator tested out fine. Not running any codes...Now what?

Was the battery "load tested"? lotso f auto parts stores just test for 12 Volts across the terminals. You ned to have it load tested. Thats where a load simulating the starter is put on the battery. I have a carbon pile tester that places 500 Amps on the battery. many times I have seen a battery show 12 Volts and fail the load test due to a dead cell.

If it's a side terminal battery, it's really hard to get a good clean connection.
