JVC BNVG121US Camcorder Battery Replacement

The Kastar BN-VG121 replacement battery is designed as a direct substitute for JVC's BN-VG107, BN-VG114, BN-VG121, and BN-VG138 camcorder batteries, providing broad compatibility across JVC's GZ-E, GZ-EX, GZ-GX, GZ-HD, GZ-HM, GZ-MS, GZ-MG, and GZ-G series camcorders. With a rated capacity of 3300mAh at 3.7 volts, it offers a substantial increase over the standard BN-VG121's approximately 2100mAh, giving you more recording time between charges—a practical advantage for events, travel, and extended shooting sessions.

The lithium-ion cell provides stable voltage delivery throughout its discharge cycle, helping maintain consistent camcorder performance until the battery is depleted. It fits directly into the existing battery compartment with no modifications required and charges using your original JVC charger or any compatible third-party charger. While only one battery is included in the package, pairing two of these higher-capacity cells gives videographers a reliable power solution for full-day shoots without dependence on wall power.
