With tightening budgets and needed repairs it is time to consider doing it yourself. However, having the right type of tools to complete the job is essential, whether you are fixing the door hinges or putting up crown molding to give some character to your living room.
The basic rule of getting a replacement battery is that it should have the same voltage as the original. An 18V drill cannot run on a 12V battery. It can only run on a 18V battery. The other thing is that the physical packaging of a battery can be different from company to company. A 12V Ryobi battery may not fit into a 12V Makita cordless drill unless the battery has the right physical dimensions. So make sure the replacement battery looks the same as the old one before you order it. Also, if you are looking for a replacement battery of the same voltage rating and by the same company, know that battery technology is changing rapidly. An 18V lithium-ion battery has a different physical packaging than a NiCad 18V battery.
Why is this important? If you have a relatively new PC the only problem you will get are error messages relating to the clock on start up. No big deal. If your PC is older then a low battery could be a nightmare. I had a PC which once li ion stock every few months refused to boot. Rather than take the PC in for repair or start replacing parts myself the first thing I did was look at the BIOS settings. It was soon obvious that the BIOS settings were corrupt (wrong bus speed). I put a volt meter on the battery and sure enough it was reading 2.2 volts.
Once charging is complete unplug it. Do not leave it connected to the power. Even though it is charging no more, it can heat up your battery and decrease the battery life.
I'm always on the lookout for a good Bluetooth headset and headphones. I found both at the Jabra booth. My favorite is the Jabra BT8030 Bluetooth speaker and headphones. This is a first-time combination that is unique of the market. You can remove the headphones fold them out and they become speakers that broadcast your sound with Ziree Power Lithium battery stocks Bass for a surprisingly full rich sound environment. These are a must have in my mobile pack.
Lithium mines Ontario-Ion batteries are revolutionary in fact, not just simply better than Ni-Cd. They don't have memory effect, which means you can easily use them a little and then partially recharge them just to discharge them to a certain percentage of their capacity other than zero. They like partial charges and discharges better than full ones, but memory effect is not something you should be aware of.
Battery memory affect is the length of time a battery will work before it needs recharged. The battery 'learns' such period of time through how you use it. If you repeatedly use your laptop for one hour and then charge it, its battery will learn to stay strong for only one hour. Using a Lithium battery and using it until it is almost dead and then recharging it will greatly increase the period of time that the battery will stay strong. Please make sure to read the manufacturer owners manual to also find out more about the battery life.
Using these easy tips to keep the battery in the best condition won't do wonders, but will let you use it to the maximum number of recharges. Ever wondered why some laptops keep their maximum capacity for 3-4 years, while others dive under an hour of runtime in one? This is why.
