I grabbed this 2-pack for my JBL PartyBox Stage to keep the music going all day. Each battery powers through long sessions, enough for 15 hours. Switching it out is fast, just pops right in, with minimal break. The USB-C charging simplifies things; I recharge it from my big power bank or the car easily, no special cords are needed, just USB-C.I’ve not compared it head-to-head with a JBL OEM battery, but this replacement battery is performing to my expectations. For anyone needing uninterrupted music, this is a decent pick for a replacement battery.

First off for the price of 1 OEM JBL battery you get two, and that is a great deal. Plus you get two cords so you can be charging on while using the other. So for ease of use just pull one and put the other in super easy to to install..I like having extra batteries so having these around for the price reassures me that I always will have one ready and charged at hand. Batter life is as good as the OEM batteries. SO that and the fact you get two makes this a great value!
