Question about battery in LG

[jimdays]

I have an LG Lancet and the battery that is supposed to go in is a BL-41A1H.
However, I have several different batteries that are BL-45A1H and these batteries won't quite fit in the phone unless I cut away three tabs at the corners of the battery. Doing this does not expose the innards of the battery, and the battery seems to work fine. It seems to me that the tabs were added just so the battery wouldn't fit in. What is the purpose of this?

Any ideas on resolving this issue?

Those batteries were not made for your phone. They were made for the LG K10.

Smartphone batteries typically are not interchangeable between models, they're pretty much specific to each model. Basically, you're lucky that battery you hacked up didn't result in something like a minor explosion. Keep in mind that a lithium-ion battery contains a lot of chemicals and stores a relatively large amount of power so intentionally cutting into one involves some risk. There are established limitations and restrictions on shipping phone batteries because they're a potential danger, a lot of retailers just rely upon on ground shipping because of the stricter regulations shipping by air.

Save yourself a lot of hassle and just buy a battery that's made for your particular phone model.
