I calibrate monthly, but is there anything else I can do?

Should my battery be removed from my laptop when I am using it at home, plugged into a wall socket?

When using a laptop as a desktop replacement the battery should not be left in for long periods of time. The laptop will over time discharge the battery. Remove the battery – making sure that it is charged to 40% and store it in a dry, warm place. Ensure that it is wrapped protectively and nothing will be dropped on it.

The battery should be re-installed every 3-4 weeks and allowed to fully discharge. Leaving a battery in storage for longer than this without using could cause the battery to fully discharge as the circuitry of the battery itself consumes power.

Leaving a battery in a laptop while using an electrical outlet for long periods of time will keep the battery in a constant state of charging up and that will reduce the life cycle of the battery.

Battery tester is a thin film of material which changes its color when current/voltage is applied. The thin film of material is formed into a strip pattern which is then coated with conductive material at the end of the strip. By adding supply at the end this particular material changes its color.

It says in the manual to only use alkaline batteries, however I want to buy rechargeable batteries for it to limit the waste.

I can’t find anything in the UK that can charge alkaline batteries, so would it be ok to use another form of battery, like rechargeable Ni-Cd or something in a toothbrush that says only to use alkaline?

By the way it came with the 2 non-rechargeable alkaline batteries that are suitable which are 1.5V.
Any help would be greatly appreciated.

Gee u r stuck with antiquities in the UK all right get an oral-b toothbrush they work fine and include a built-incharger. U can get one for about 40$

I recently took my fully working car for a routine service, during the service they did a battery and alternator check.

Within 24 hours of the service my battery light came on, and when I took it back to garage they said the battery and alternator needed replacing.

Is there anything they could have done on service that could have caused this fault, all they did was use a battery tester.

Many Thanks
Thanks Linden,

Battery has been replaced and now has a new battery, but the alternator still needs replacing.

It just seems a little strange that I had no problems with car prior to service, and then after a battery and alternator check, the battery and alternator are damaged.

Is this just unfortunate timing.

Try tighten up the positive and negative cable on the battery to see if that will help if this doesn’t work take your vehicle to auto zone and they will check it for free.

I have an ‘07 Mustang I bought new. It has less than 27,000 miles on it. I’ve been informed that it needs a new battery, but it seems like this NEW battery in a NEW car didn’t last very long. I’ve bought used cars with the original battery that lasted longer - a 3 yrs old car with over 70,000 miles on it, drove for 2 more years on the original battery. So how long SHOULD a car battery last?
Thank You for your answers - glad I bought that extended warrenty!
That’s ford for ya~! But no…really…if you live in an area with extreme changes in temperature as well as sea salt in the air, it’s going to be a factor in the life of the battery. Mileage doesn’t really matter for batteries per se as the alternator is what handles most of the load during driving.

What I would do (prior to replacing the battery) is check the cables from the alternator to the battery to make sure they aren’t corroded or loose and preventing the battery from getting charged during driving.

And if you need a new battery I would suggest getting a Braille daily driving battery (not a racing battery). You’ll cut about 10 pounds in battery weight and get at least 50k out of them. Excellent batteries…but you almost always need to special order them or buy them online. Believe it or not a better quality battery CAN increase gas mileage (based on weight; and electrical stability to the fuel delivery and ignition systems) but generally not more than 1-2mpg.
