WORX battery for mowers and Landroid: which one to choose?

Information verified on September 5, 2026. This guide does not constitute an autonomy test. It only presents batteries and a battery kit with charger, without tool selection. Scenes are illustrative and generated; inserts use product sheet photos.

1. Identify the right WORX battery for your mower or Landroid

Stop the machine and follow the instructions to safely access the battery. Note the full model of the device, for example, its reference starting with WG or WR, then the WA reference of the existing pack. Also note the charger or station used. A readable photo of each label prevents confusing two similar versions.

WORX presents PowerShare as a shared platform, but this indication does not replace checking the model. The official guide for Landroid Classic batteries concerns a specific family: do not automatically transpose its information to another robot generation or a third-party battery.

Also check the size and closure of the cover. A pack whose contacts seem to match is not validated if its casing prevents correct locking. Never force insertion and do not modify slides or contacts to make a battery "compatible."

Finally, poor autonomy does not always blame the battery. High grass, mowing conditions, machine maintenance, and pack aging can all play a role. If the robot signals a fault, first consult its diagnostic procedure rather than ordering randomly.

2. Distinguish between original and compatible WORX batteries

An original WORX battery and a compatible battery from another manufacturer should be presented separately. The PowerShare designation on a manufacturer's guide does not guarantee the characteristics or electronic recognition of a third-party product. For the latter, look for an explicit list of accepted models, not just a photo resemblance.

The original WA3644 + WA3880 kit offered at Manuzen includes a PowerShare Pro 20 V 4 Ah battery and a charger. The original batch offers two batteries, with a 2 Ah or 4 Ah Pro variant. These options should be compared with your machine's documentation before ordering.

The WA references cited on a compatible product sheet serve as a starting point. They do not exempt you from confirming the complete device, its housing, and its charging system. If your mower or robot is not explicitly validated, ask customer service for confirmation and prioritize the reference recommended in its manual.

3. Compare 2 Ah, 4 Ah, and 5 Ah without promising autonomy

Voltage and capacity answer two different questions. Voltage must match the intended system. Capacity, expressed in Ah, allows comparing the advertised charge quantity between comparable packs, but it does not directly translate into mowing minutes.

On a device using two batteries simultaneously, follow the instructions and choose authorized packs of the same capacity and charge level. Do not arbitrarily combine different capacities or technologies to "gain more autonomy." Both batteries may be necessary for operation, and not just constitute a simple reserve.

For a Landroid, a higher capacity is therefore not an automatic purchase. The accepted format and charging conditions take precedence over the number printed on the label. We do not announce any gain in area, duration, or longevity without measurement adapted to the model.

4. Choose from available batteries at Manuzen

If you are looking for an original solution: compare the pack of two WORX batteries and the WA3644 + WA3880 kit. The pack allows selecting the offered capacity; the kit provides a 4 Ah battery and its 2 A charger. Check if you need a single pack, a pair, or a set with a charger.

If you are considering a compatible one: the 4 Ah formats, individually or in packs, can be examined for devices explicitly accepted on their product sheet. The 5 Ah pack remains reserved for authorized references, with the exclusions mentioned above. The term "compatible" does not mean original battery, nor validated equivalence for every robot.

Do not deduce the delivered content from a photo alone. Check the variant, the number of batteries, and the possible presence of a charger. The buttons in the selection lead directly to the pages to check the current price, details, and conditions before ordering.

5. Charge, store, and replace the battery with care

Only use the charging system designed for the pack. Charge in a dry, ventilated area, on a stable surface, away from easily flammable materials, and observe the temperatures indicated in the manual. Allow a warm battery to cool down before recharging it.

A swollen, cracked, abnormally hot, or unusually odorous casing requires stopping use. Do not disassemble the pack and do not attempt to reactivate a battery with improvised electrical wiring. Contact the appropriate service and follow suitable collection instructions.

For winter storage, follow the robot's and its battery's instructions: recommended charge state, storage location, and periodic checks may vary. Keep contacts clean and protected; do not store the pack loose with metallic objects.

Key takeaway: the right WORX battery for your mower is first and foremost one whose compatibility is confirmed. Compare the offers in the selection above or have your references checked before purchase →. A higher capacity never compensates for an unsuitable model.
