I put the two AA batteries in that came with it and now they will not come out. I have tried everything. They just wont come out of the battery pack. What to do ?

Pliers. Sometimes shaking doesn't work, so I just grab my pliers, and yank them out.

I have a 1978 corvette. Dash lights went out, signal lights quit working, power locks don't work and the battery will drain in about a week if I leave it hooked up. All fuses have power on both sides.
Is there a tester available that will tell if a wire is grounding out.

Save yourself some time and effort and learn how to use a digital Volt Ohm Meter (VOM). They are readily available at Sears for about $30. They are simple to use once somebody shows you how. For measuring your battery voltage, just switch to the "20 Volt DC" scale, and hold the test probes on the battery terminals. You should read at least 12.6 Volts DC for a fully charged battery after the car has been parked for a couple of hours. With the car idling, you should read 14 - 15.5 Volts DC depending on battery charge and temperature. You can also easily measure the current in Amperes that is being drawn out of your battery while the car sits overnight (called "parasitic" current draw). This reading should be less the 1/4 Ampere (250 milliamperes). You simply set the meter for the "10 AMP" scale and connect one lead to the negative battery terminal and the other to the black battery cable that was disconnected from the negative battery terminal. If the reading is more than 0.25 Amperes, start pulling fuses one at a time to see which one causes the AMP reading to drop below 0.25 AMPs (1/4 AMP). Reinstall that fuse after each test. Make sure all the doors are closed and the courtesy lamps are all extinquished including an underhood lamp if you have one.
Finally, to measure for short or open circuits, remove the battery cables from the battery and switch the VOM to the lowest "Resistance" measurement scale (ohms of resistance). Readings near zero ohms mean a dead short as when you measure a short length of copper wire. Read the manual that comes with the meter. However, some standard electrical resistance readings for coils and bulb filaments for example are normally very small (less than 10 ohms).

I recently left my lights on for about 5 hours on my 94 Saturn and killed the battery. I got a jump and drove up the street to the grocery store, ran in for 20 minutes, and it wouldn't start. I was wondering about how long I would need to leave the car running to make sure that after the next jump, if I park it overnight, it will start the next morning. Battery is about 3 years old.

Also, do I need to actually be driving or can I just have the car running? Will it charge the battery either way?

3 year old batt
time for a new one

I know that in a diesel truck(2 batt syst.), both batteries must be good or they will only charge to the ability of the poorest battery. That seems to be the case with a commercial floor scrubber I'm working on. The SG of the cells range from poor to 1.275. Two batteries have dead cells while some batteries are "fair" or a little better. If I don't change them all, will it have any ill effects on the new batteries?

JUST LOAD TEST THEM INDIVIDUALLY,REPLACE THE BAD ONE ONLY,BUT REPLACING THEM ALL WOULNT HURT EITHER.

during driving my battery light came on checked it with battery tester it shows it's working with alternater, the car starts up but the light stays on checked the electrolyte it was low filled it up taken the battery terminal cleaned them still same battery lights up when you starts the battery light dimmming then when hit the accelarater it brightens do i need a new battery had the car for 4 years battery not changed

there's 3 diodes in the battery, when one fails i becomes a dynamo without a regulator and the light tells you there's a problem, but not enough to break down for a while,you need a new alternator, you could fry something without the over voltage protection

My friend's husband is in Iraq, and his 4 wheeler's battery is dead. His wife needs help removing the battery so she can bring it to Napa to get it checked out, but we know nothing about removing batteries. Anybody know?

take the seat off, take the 2 screws out of the terminals, lift it out

I have a motorcycle with no battery. However, I have another motorcyle with a battery, but it’s a different size and won’t fit in the first motorcycle’s battery cage.
If I just want to check and see if the battery-less bike runs, can I just set the battery next to it and connect the terminals, and start it up?

The questions is, are there differences in batteries besides size? Will this ‘test’ work, or will i damage the first bike?

thanks in advance

The difference is voltage and amperage.

You can certainly hook the battery to the bike and run it for a while for a test, but if the battery amperage does not match the charging system of the bike, then over time the battery will either run down, or be over-charged and ‘cooked’.

But certainly perform the test by all means.

You press down on them, there's usually one at each end, and when you press down, a little stripe sort of charges up like a gauge. How the heck does this work?

There is a strip of conductive material that is sensitive to voltage. When you press the two ends, you engage the strip to each end of the battery. The strip has certain resistance that if the voltage exceeds that resistance, it will light. The less voltage, the fewer parts of the strip will light.

My laptop battery is well overdue for a replacement. I have a Dell Latitude D820. The battery on Dell’s website costs about $189 however I know there are substitute brands for much less. Does anyone know a reliable battery website? Or does anyone have personal experience with secondary manufacturer batteries? Thanks!

Yes…I get my batteries from www.batteries.com. They have good cheap batteries for everything. I have bought camcorder batteries and also a tripod for my olympus camera. It have good prices and they work great.

I just recently bought a new Olympus FE-210/X-775. I have Duracell rechargeable batteries that I used on my old digital camera and it could go for days but when I put them in all my new one my batteries died fast. Does anyone have any recommendations? Thanks.

camera that uses 2 AA bateries always runs out of battery quick. get some bigger battery like 2500mah or above. the biggest i've seen is 2700
