Product information

This NiMH high-performance battery is the most powerful replacement solution for Hetronic radio remote controls that operate on 3.6 volts. It replaces the original batteries with the numbers 68300600, 68300900 as well as 68300800.

With a capacity of 2,100 mAh (2.1 Ah) this battery offers the technical maximum for this size. Compared to older standard batteries (often 1,200 mAh), you get almost double the runtime. It is frequently used in the Ergo, Nova-S (3.6V versions) and certain Mini variants.

Highlights at a glance

Maximum capacity (2.1 Ah): With 2,100 mAh, this battery is a true long-lasting performer. It is ideal for applications where the transmitter must be used for very long periods (e.g. multi-shift operation) without charging.
Specific 3.6V voltage: Designed for the 3-cell Hetronic systems. It is not compatible with the 9.6V devices, although it looks similar at a glance. Voltage is crucial.
Full replacement for 68300xxx: Replaces directly the original numbers 68300900 (NiMH), 68300600 (NiCd) and 68300800.
Environmentally friendly upgrade: Modern NiMH technology eliminates the memory effect of old NiCd batteries (68300600) and avoids toxic cadmium. You can recharge the battery flexibly at any time.
Fit accuracy: Has the typical (mostly black) housing with the specific contacts for the 3.6V slot in the transmitter.

Compatible transmitters (extract)

Please check the nameplate of your transmitter or the old battery for the voltage 3.6V before purchasing:

Hetronic Ergo: Ergo, Ergo-F, Ergo-M (transmitter in "banana shape").
Hetronic Mini (3.6V): Rarer than the 9.6V version, but occurs.
Hetronic Nova-S / Nova-M (3.6V): Special versions.
Hetronic GL (3.6V): Older models.

FAQs about the Hetronic 3.6V 2100mAh battery

My old battery only has 1200 mAh. May I use 2100 mAh?

Yes, absolutely. The higher capacity (mAh) is merely a larger "tank". The voltage (3.6V) remains the same. Your transmitter lasts noticeably longer with this battery than the original, with no risk to the electronics.

Warning—risk of confusion: 3.6V or 9.6V?

This is the most important point with Hetronic:

Part number 68300900 / 68300600: This is this battery (3.6V).
Part number 68300500 / 68300520: This is the 9.6V battery (looks almost the same!). Please check the number on your old battery closely. The systems are not compatible with each other.

Why does it say "HTC" in the description?

"HTC" is often used in industry as an abbreviation for Hetronic. It has nothing to do with the smartphone manufacturer. If your battery reads "HTC" and a number starting with 683..., it is a Hetronic battery.
