There are two options available to you when your battery stops working as it should. First, you can buy a new one. Or, you can choose to recondition it. If there’s no damage to the battery, reconditioning is usually a good option.

2). Connect the red clamp to the positive pole (+), black clamp to the negative pole (﹣).
When a lithium-ion battery’s series cell groups are not in perfect balance, much more stress is placed on the lower cells. This is because as a cell’s voltage is lowered, its internal resistance increases. This means that if you are running a battery with one or more low-cell groups, those low groups are aging faster than the other cells.

Well, I will still ask, Maybe someone out there can help. Have a HP DV7 Notebook with a 9C battery. 3 cells died over night. from running normily to zero. Disassembled battery to find 3 cells died. zero Volts. Replace the 3. Now have ~12.6V. Will not charge in windows, Shows 80%. ran Bios battery test. Battery status : Replace (42). was wondering if anyone out there has a way to reload the firmware in the battery charging pcb or edit that data? Many thanks David A.
At Midas, it takes 20-30 minutes to replace a car battery on most vehicles. Our battery replacement service includes cleaning the battery tray and terminals to get rid of battery acid and other debris. We also recycle your old battery.
Give the battery another overnight charge as described in Step 6. The Epsom salts should remove deposits on the battery plates which previously prevented the battery from taking a full charge. Check the battery in the morning. If the battery still won't take a full charge, it likely cannot be saved. If the battery has taken a charge, replace the cell caps and use your cart normally. Put a trickle charger on the batteries every night to keep the batteries in peak condition. Use only distilled water inside your battery. Never use tap water as the chemicals in tap water will destroy your battery. Do not get battery acid or the white/yellow corrosion on the batteries on your skin or clothing as this acid can burn and destroy material in a very short time. Always wear gloves and eye protection when working on lead acid batteries.Always be sure to properly maintain your golf cart.
Hi battery doctor, I bought a car battery 38Ah for my Nissan Cube and used for 7 months and there after parcked it after noticing a knockin sound. Later after 4 months, I have attended to the knocking sound but now the battery is not holding the charge. I have just noticed the battery acid is a little below the cells level. Do I need to just add distilled water or follow your dead battery reconditioning process, or if better still, drain the battery and refill with fresh battery acid? Please help and thank you most sincerely in advance.
Where I can find the schematic circuits and components list: SMBus adapter parallel port?? AccPlus program is useless, if not physically connect the battery to the PC through the parallel interface. View picture here: http://www.microsys.ro/pi3.jpg
