The BP120MH is a Nickel-Metal-Hydride rechargeable battery pack designed as a replacement battery for Fluke 120 series ScopeMeters and Fluke 43 and 43B Power Quality Analyzers. It delivers a nominal voltage of 4.8V with a capacity of 3000 mAh, providing 50% more capacity than the original BP120 battery, resulting in significantly longer operating time at the same volume and weight. The battery is environmentally friendly, containing no heavy metals unlike the earlier NiCd batteries, and can be charged while installed in the instrument using the PMB907 power adapter/charger. The BP120MH serves as a direct replacement for both the earlier BP120 and BP130 models, offering users extended runtime and improved environmental compliance for portable test and measurement instruments.
