Connecting batteries in parallel – BatteryGuy Knowledge Base
Peter, You never want to mix battery chemistries together. NIMH is meant to be recharged and Alakaline used and thrown out. Very bad idea. If an Alkaline battery were to be charged with a NIMH in a device with a charging circuit, it would probably explode in the device and ruin the product it was in.
mixing different brands of LiFePO4 batteries
2) Each brand comes with a different lifespan, so if you mix, you might need to put watt meters on each battery in order to monitor and compare outputs to get some idea of the remaining capacity of the batteries. In ANY case, each battery should be separately protected by its own fuse. I use 75Amp fuses on each of my 100Ahr batteries. That can eliminate the …

Connecting batteries in series – BatteryGuy Knowledge Base
This means that if you have two batteries in series of the same voltage and amp hour capacity that you have been using for a while, but replace one with a new unit, what you have in reality is one battery with a higher voltage and amperage (the new battery) than the other older battery. The result is that the older unit will incur greater damage through over-discharge and over …
Is it safe to replace a 4400mAh laptop battery with a 8800mAh battery?
With modern laptops (at least the last 15 years) it is not necessary to match voltages. It is very common for manufacturers to offer several different battery packs for a single laptop model. These will differ in the number of cells in the pack. In some cases, the pack with more cells will have a higher terminal voltage. THe laptops cope just ...

Why Proper Cell Balancing is Necessary in Battery Packs
The use of cell balancing enables us to design a battery with larger capacity for an application because balancing allows the battery to achieve a higher state of charge (SOC). A lot of companies choose not to use cell balancing at the start of their design do reduce cost but without the investment in the cell balancing hardware and software, the design does not allow the SOC …

Can batteries of same voltage but different capacities be ...
When batteries are connected in series, their capacities do not add up directly. Instead, the capacity of the battery pack is determined by the lowest capacity battery in the series. In a scenario with a 15Ah battery combined with a 20Ah battery in series, the overall capacity of the battery pack will be limited to 15Ah, despite the larger capacity of the 20Ah …
