Should a battery pack be replaced?
If a relatively new pack has only one defective cell and a replacement is located, exchanging the affected cell makes sense. With an aged battery, however, it’s best to replace all cells. Mixing new with old causes a cell mismatch that has a short life. In a well-matched battery pack all cells have similar capacities.
What are the replacement strategies for battery packs?
The replacement strategies considered two scenarios. The first scenario, the replacement of an early life failure, addresses an important open question for maintenance of battery packs. The traditional approach in pack maintenance is to replace all cells at once to control the mismatches.
Can lithium ion batteries be reused?
The second scenario for reuse of lithium ion battery packs examines the problem of assembling a pack for less-demanding applications from a set of aged cells, which exhibit more variation in capacity and impedance than their new counterparts.
How do you build a battery pack?
Building a battery pack from individual cells generally requires a degree of dexterity, electrical expertise, and a spot welder. As you can see from the old unwrapped battery pack in Figure 3, the five green cells are neatly connected at the positive and negative contacts via thin, spot-welded nickel strips.
Can a battery shop reuse a failed battery pack?
A battery shop may salvage good cells from a failed pack for reuse but the recovered cell should be checked for capacity, internal resistance and self-discharge – the three key health indicators of a battery.
How do I get a new battery pack?
The simplest solution is to visit the equipment manufacturer’s website to see if a replacement battery pack is available. Sometimes there isn’t and, when there is, the prices can come as a shock. In my case, the equipment worked just fine and looked to have a good few more years of life in it — a new battery would suffice.
