Direct replacement for Juniper field computers

This 4500mAh 3.6V Ni-MH battery replaces the original pack in Juniper AMX-2, AMX-3, AMX-4, AMX-5, AMX-1, Allegro CX, Allegro MX and VR-151 GIS handhelds. It matches the VSH-H11U and LHJBT-H11U part numbers so survey crews and field engineers can swap cells without tools. Overcharge, over-discharge, over-voltage and short-circuit protection are built in.

Compact pack with certified safety

The cell measures 71.5 x 56.0 x 19.0mm and weighs 232.0g, fitting the existing battery cavity exactly. It carries ISO9001, RoHS, CE, UN38.3 and MSDS certification, confirming toxic-free materials and transport compliance. The 1-pack format means one complete swap per purchase.

Ni-MH chemistry limits runtime and charge speed

At 3800mAh typical capacity and 13.68Wh energy, the pack suits a full day of intermittent logging but will not match lithium-ion energy density. Ni-MH self-discharge requires periodic top-ups if the unit sits unused for weeks. No fuel-gauge protocol is provided, so remaining capacity must be judged by device runtime.
