Not maybe. If it were profitable to do, it would be done already. The battery has to scale up with the size of the vehicle, even in a hybrid, and the battery is insanely expensive. Scaling it up to a truck is not worthwhile if you are still building an entire combustion engine in there also. That's why it doesn't exist.
You have more systems, and thus you have more maintenance than you would with just the engine or just the battery. You have both, so you have more maintenance than either would have by themselves.
Electrics have not had insane problems. They're awesome at everything they're doing. The tech is naturally rolling up the size and scale ladder. UPS can't easily adapt because you almost have to start with a new facility designed for electric trucks. You can't charge 300 package cars overnight at a regular hub. You have to start with a building and grid designed for it.
