Replacement battery for Midland ER200

This lithium-ion pack replaces the original BATT20L cell in Midland ER200 and ER300 DAB digital radios. It delivers 3.7 V and 2600 mAh capacity for portable listening. The blue housing matches the original colour scheme. Buyers needing a battery for other Midland models or different radio brands should look elsewhere.

Li-ion chemistry limits runtime and charging cycles

The 2.6 Ah lithium-ion cell stores 9.62 Wh of energy within its 67.88 x 18.44 x 18.44 mm form factor. Like all Li-ion packs, capacity gradually reduces after repeated charge cycles and extreme temperatures shorten overall lifespan. The radio’s own charging circuit controls the recharge process. Users expecting indefinite runtime without degradation will find the chemistry does not support that.

Confirm your radio model

Verify the device is an ER200 or ER300 before ordering because the connector and shape are specific to those units. Check that the 67.88 mm length and 18.44 mm diameter fit the battery cavity without forcing. Ensure the radio’s charging circuitry is functional so the new cell can be recharged safely. Buyers with damaged charging ports or incompatible models cannot use this pack.

Questions about this item

Which capacity should I choose for my Midland ER200 or ER300 radio?

This pack is a single 2.6 Ah lithium-ion cell rated at 3.7 V and 9.62 Wh, the only capacity offered for these models.

What does the 2600 mAh rating mean for actual run-time?

It stores 9.62 Wh of energy; real-world operating time depends on the radio's power draw and volume level.

What connector standard does this battery use and what does it limit?

It fits the Midland BATT20L compartment directly, so the physical shell and contact layout set the compatibility boundary.
