Direct Replacement for Optex iVision-L

This Estry Ni-MH pack matches the original 3.6V 700mAh specification for the Optex iVision-L Wireless Two-Way Interc. It delivers 2.52Wh in a 45.6 x 31.3 x 10.6mm form factor weighing 74.5g. The cell is certified to ISO9001, RoHS, CE, UN38.3 and MSDS standards. Overcharge, over-discharge, over-voltage and short-circuit protection circuits are integrated.

Protection Circuitry Extends Service Life

The built-in safeguards prevent the common failure modes that shorten Ni-MH packs in always-on intercom use. By limiting voltage extremes and cutting off shorts, the board helps the battery reach its rated cycle count without swelling or premature capacity fade. No extra charger or firmware is required; the pack fits the existing charging cradle.

Suits Owners Needing a Like-for-Like Swap

Buyers restoring a single Optex iVision-L handset will find the correct voltage, capacity and physical profile here. Those needing higher capacity, a different chemistry or a multi-pack bundle should look elsewhere. The pack is sold individually with a one-year battery warranty.

Questions about this item

How often will the 700mAh Ni-MH pack need replacement in the Optex iVision-L?

The supplier rates the pack for a one-year cycle under normal use; plan to swap it annually or when talk-time drops noticeably.

What limit appears first during a long conversation on the iVision-L?

The 700mAh capacity sets the talk-time ceiling; once the 2.52Wh reserve is drained the handset must be recharged.

Does the 3.6V pack run hot or draw extra power when the intercom stays on all day?

Built-in over-charge, over-discharge and short-circuit protection keeps temperature and current draw stable during continuous operation.
