What’s the most important factor in buying replacement batteries? Expiration date! Dollar for dollar, alkaline batteries with a distant expiration date (fresher battery) will give greater value than an expensive battery that will expire sooner. Check the side of the battery to determine its DCvoltage. Commonly, AA, AAA, C, and D are 1.5 V, and rectangular batteries are 9V. Set the multimeter to the VDC (volts of direct current) scale. Touch the red multimeter probe to the battery’s [+] terminal and the black probe to the [-] terminal. If the reading is more than 10 percent below the rated output (1.35 V or 8.1 V), the battery is bad and should be replaced.
Test your the voltage on your battery pack again. It should be higher than it was before boosting. IF IT IS NOT, THEN STOP. YOUR CELL COULD BE DAMAGED AND CONTINUING COULD BE DANGEROUS.

I have just brought a new charger for my Toshiba laptop to replace an old one that had a wire exposed and damaged. The new charger is supplying the correct voltage and turns my computer on and displays 0% available (plugged in,not charging) Is there power surge protectors installed to avoid damaging your battery or computer hardware on toshiba laptops? Could the damaged wire have caused a problem with the battery or with my laptop itself ?
You will also need to be aware of compliance issues. Unlike other regulated standards, the SMBus allows variations and this can cause problems. The repaired SMBus battery should be checked for compatibility with the charger. Batteries for critical uses, such as heathcare, are typically replaced and not repaired. See also www.sbs-forum.org and www.acpi.info. Please when a laptop battery is replaced and there is no voltage at the outer terminals, but there is at the battery terminal. (1) What are the appropriate steps to take to get this rectified without damaging the BMS.
We don’t recommend to run your car without a new battery or a decent quality battery. In doing so you are causing to much stress on the alternator which will eventually fail. The end result is a bigger repair bill. We don’t want that for you. Always replace the car battery in time.
I didn’t realize that there were certain car batteries where they have distilled water that needs to be refilled every 4 months. Is this a common type of car battery? How would I know if this is what I have in my car, and how to maintain it?

Hi, my P755-S5285 Toshiba Satellite Li-Ion laptop battery pack PA3817U-1BRS seems to have died..10.8V 4200mAh. Inside it has 6 x SANYO K UR18650A R2112 cells... 1. Can these be safely replaced? 2. What are the best replacement Li-Ion batteries to use to replace the SANYOs? 3. Is it 3.6V or 3.7V...? 4. What mAh capacity would be best to use? 5. Can I increase the 4200mAh to what amount and how? 6. What do the ''K'' and ''R2112"' and 'P23B'' etched on the cells' plastic covers mean? 7. How can one identify and differentiate clearly between the various types of these Li-Ion batteries? Thanks to all your comments and advice.
Also , is that an apothecary behind you in your photo ? I've been wanting to make one for my wife for awhile now and could use any tips or pointers I can get . Oh and I'm building it all from pallet wood and other reclaimed wood to give it some more character and also it will make It look more aged is my hope anyhow lol
The Li-ion battery i have is sealed, no screws at all, can i still pulse charge this battery using the +- terminals that are visible on the outside of the battery? (its a godox VB18 camera flash battery DC 11.1V 2000mAh)
Hai... My hp laptop battery is down for about one month...it is not charging, but i still using by adapter...is there any problem using lptp without battery?
Hi I have Samsung Series 9 ultrabook NP900 X3B A01UK. This ran out of charge and the light on the charger was not on. I replaced the charger with an originL Samsung unit the laptop powered up however the charger appeared to fail immediately and the laptop shut down. On unplugging the charger it was quite warm and again the power light is not on even though the fuse has not blown. It appears something in the laptop is causing the charger to fail. Do you have any advice, could this simply be caused by a failed battery or something more seriously wrong with the laptop? Kind Regards Len
Step 2: Make sure there are no cracks in the conductor and no burn marks on the cells. Also, make sure there is no liquid coming from anywhere.

Use a voltmeter to locate the positive and negative battery terminals and establish the polarity. If no voltage is present, a solid-state switch may be in the “off” position and needs activating. Connect the voltmeter to the outer terminals, take a 100-Ohm resistor (other values may also work), tie one end to ground and with the other end touch each terminal while observing the voltmeter. Repeat by tying the resistor to a positive voltage potential. If there is no response, then it is possible that the battery is dead or locked by a code. The 100-Ohm resistor is low enough to engage a digital circuit and high enough to protect the battery against a possible electrical short.
