Batmax Replacement Battery for JBL Flip 3 4 5 Charge 2+ 3 Xtreme Boombox Pulse

Batmax JBL Speaker Battery Features and Specifications

This high-capacity lithium-ion cell is precision-matched to the voltage and capacity requirements of JBL Flip 3, Flip 4, Flip 5, Charge 2+, Charge 3, Xtreme, Boombox, and Pulse 2/3 speakers, so you never settle for reduced playback time. Wide speaker compatibility means a single replacement covers multiple JBL models you may already own, reducing the cost of keeping every device charged. Safe overcharge protection circuits monitor voltage, current, and temperature throughout every charge cycle, cutting risk of heat damage or swelling that aging OEM cells often exhibit. The long runtime performance matches or exceeds original factory capacity ratings, giving you extended listening sessions between charges. Batmax grades every cell through discharge-cycle testing before shipment, so the battery you receive is verified to perform from the first use.
