Can I replace my laptop battery with a lower voltage?
No, you can’t. Motherboard of laptop has several regulator such as buck, boost or buck-boost converters. They are used to supply voltage to CPU, RAM, Storage devices, etc. If you change the battery with different potential, these values will be disturbed and most likely the motherboard is going to die.
Can I replace battery with lower voltage?
Replacement batteries should only be purchased when the voltage is reasonably close to that of the original battery. So, if the original battery is a 3.6 volt, a 3.7 volt replacement battery will work perfectly fine. However, a 7.2 volt battery may cause damage to the device in which it is used.
Can I replace 11.1 V battery with 14.8 V battery?
Please check your original battery,if the voltage is 14.8V(or 14.6V,14.4V),then this battery will fit your laptop. If your original battery voltage is 10.85V or 11.1V,this battery will not work for your laptop.
Is it OK to use higher voltage battery?
A higher voltage battery has the potential to “push” more current–that is, more electrons–for a given resistance. This translates to the capacity for greater work, which is the same thing as more power. Higher voltage also means less current to do the same amount of work, so longer battery life.
Can I use a higher mah battery in my laptop?
Absolutely yes you can replace. In fact there are extension available to connect higher AH batteries. So long as voltage rating is compatible, it is perfectly fine to use higher AH batteries, if space with the laptop is not adequate, extender is available to connect the battery from outside.
How much voltage difference is acceptable for a laptop battery?
The voltage difference of 0.3vdc is well within tolerances. If the battery fits the case and the voltage differences are +/- 10\% you should be okay. The battery charger and the Laptop voltage systems will only bring the battery up to the 10.8 level, so you will be okay.
Is it safe to charge a laptop with a 30-volt power supply?
It depends on the each company policy for product design. Some companies would just stop the charging for higher and lower voltage. The other companies would be broken even slightly higher and lower voltage. If you were using 18V AC adapter, over 30V input would be dangerous even the “big company” laptop.
What happens if the voltage is too low on a laptop?
The lower the voltage on the input the harder it is to maintain the required voltage. For ie, if it uses 15v input and regulates it to 12v, but if the input is 12v then the output will drop, probably too low for it to operate. a lower voltage won’t hurt anything if you want to try it but going higher could eventually burn the laptop up.
Can I charge my laptop battery with a battery charger?
The battery charger and the Laptop voltage systems will only bring the battery up to the 10.8 level, so you will be okay. Just make sure the vendor of the battery certifies that it will not damage your system and is designed to work with your system.
