Replacement battery for NTI Environment monitors

This 7.4V 2600mAh lithium-ion pack replaces the original power source in NTI Environment E-MINI-LXOB, E-2DB and E-5DB monitoring units. It delivers 19.24Wh of capacity and matches the OEM form factor at 133.50 x 18.60 x 18.40 mm. The blue housing identifies the pack at a glance during maintenance.

Upgrade from a depleted or aged original cell

When the factory battery no longer holds enough charge to bridge mains interruptions, this unit restores the specified backup runtime. The jump is worth it if the monitor reports low-battery alerts or fails self-tests after extended power cuts. It is not for buyers who need a higher-capacity pack or a different chemistry than the 2.6Ah lithium-ion design.

Verify the exact model and connector before ordering

Confirm that your monitor carries the E-MINI-LXOB, E-2DB or E-5DB designation and that the existing pack measures 133.50 x 18.60 x 18.40 mm. Check that the voltage label reads 7.4V and the connector polarity matches the original. This battery is not for systems that require a different voltage, capacity or physical layout.

Questions about this item

What are the exact dimensions of the 133.50 mm long blue Li-ion pack so I can confirm it fits the E-MINI-LXOB compartment?

The pack measures 133.50 x 18.60 x 18.40 mm, matching the original E-MINI-LXOB battery cavity.

Which connector orientation does the 7.4 V 2600 mAh cell use when sliding into the NTI Environment E-2DB or E-5DB monitor?

Align the blue pack’s keyed plug with the monitor’s recessed header; the polarity notch faces the label side — reversing it prevents contact.

After how many years should I plan to replace the 19.24 Wh Li-ion back-up in my E-MINI-LXOB unit?

Typical service life is three to five years; swap the pack when the monitor reports low back-up voltage during self-test.
