I have FP 06 10.8 Volt 47 wh ( 10.8 volt 4100 mAh) hp battery in my laptop. it was not working for long . I have dismantled it . Found 6 cells of 18650 of 3.7 volts each in side it . I want to replace its bed cells. I have 18650 3.7 volt 2200mAh Cells. can the existing cells be replaced with available 2200 mAh cells.
After cleaning battery acid from the battery, you have to recondition it. For that purpose, fill the cell with electrolytes again. The electrolyte is usually made of distilled water and Epsom salt. This allows the battery to charge quickly by avoiding sulfates. Then, pour it in the battery.
.
If you notice any cracks or leaking battery acid, do not attempt to recharge it. If you see some corrosion but the rest of the dead car battery looks okay, start by cleaning it with battery cleaner and a battery terminal brush. Once the battery is cleaned off and its cables are secured, you can jump-start your vehicle. CRC Battery Cleaner 14.29 $ Buy Now Ultrapro Battery Terminal Brush 11.59 $ How to Jump-Start Your Car

That’s exactly what I was thinking. I worked on electronics 25+ years in the military, so I know a thing or two. Those two terminals that the battery uses to make contact with both the charger and tool are no different than the contacts within the battery. So doing this pulse exercise on those exterior contacts will
Since golf cart batteries are generally under the front seat this requires that the front seat be lifted out of the cart. On some cart models the front seat is hinged and the front of the seat is lifted straight up.
The positive and negative terminals are usually placed on the outside; no norm exists on the arrangement of the other contacts.

Hi, I have a laptop battery which is suspect. However, I am not sure whether it is a problem with the cells or a problem with the way the laptop is charging the battery. I have opened up the battery. It is organised into three pairs of cells. Each pair is connected in parallel. I don't want to disconnect the cells from the battery circuit board, so I was wondering if I can connect my 18650 battery charger and charge (in place), each pair of batteries in turn?
Hi, could you be more specific of how we can add this secondary voltage through a 100-Ohm resistor before we remove the old cells from the BMS? How can we practically do that? It would be nice if you also show us a picture of that. Thanks Sav
Is there really a need to pull the battery case apart to do this. Can’t the same be achieved by touching the terminals when it is still fully assembled?!
thanks for answer,battery chatging time is ok.onliy problem is wrong voltage displaying!
The battery appears to be losing 1-2% of its initial charge every day. If discharge continues at that rate, the vehicle would need to be driven (or battery otherwise recharged once per week) to stay in usable condition. I wouldn't use it as a primary battery in a vehicle, but left tended it could be put into "service" as a backup battery should my friend run into trouble with his new battery.
If you’re in a remote or rural location, don’t worry, we can still help repair your phone, with fix2U’s Express Mail In Service. In addition, we even cover all shipping charges both to and from our repair centre.
Charge your battery with a slow charger. It’s best to have it charging for at least 24 hours before testing it and reinstalling it in your vehicle.
So easy to have someone come to me to replace my iPhone battery on the spot. No hassle and cost is reasonable. No need to hand in your phone for a few hours...
