Estry standard battery 700mAh 8.4V for AEMC PEL 102 6417 PEL 103

Direct replacement for AEMC ground testers

This 8.4 V nickel‑metal‑hydride pack matches the original specifications for the AEMC PEL 102, 6417 and PEL 103 ground testers. It is built to the same electrical and mechanical tolerances as the factory cell. Safety circuits guard against overcharge, over‑discharge, over‑voltage and short‑circuit events. The unit is certified to ISO 9001, RoHS, CE, UN 38.3 and MSDS standards.

700 mAh capacity with 5.88 Wh energy reserve

The 700 mAh rating delivers 5.88 Wh, enough for extended field sessions on a single charge. Runtime scales with the tester’s measurement load, so heavy continuous use will deplete the pack sooner than light intermittent checks. When the voltage drops below the instrument’s operating threshold the tester will shut down, signalling the need for a recharge. No higher‑capacity alternative is offered in this form factor.

Compact sealed pack with integrated protection

The sealed nickel‑metal‑hydride construction requires no maintenance and produces no audible noise during operation. Self‑discharge is low, so the pack retains usable charge after weeks in storage. Operating temperature range follows standard Ni‑MH limits; extreme cold or heat will reduce available capacity temporarily. The built‑in protection circuitry limits current spikes, keeping the tester’s power draw stable and predictable.
