Bicycle battery Koga

Koga has used several systems, including E-motion and ION (also used by Sparta and Batavus), Bosch and Bafang. Look at the label on your current battery for the part number, for example 29110753 (E-motion) or 0.275.007.539 (Bosch PowerTube 500), and search for it in the search bar or the battery finder.

If you have a Bosch system, also look at Bicycle battery Bosch. Not sure? Send a photo of your battery and of the label via WhatsApp.

Often it does: Koga, Sparta and Batavus have partly used the same systems, such as ION and E-motion. On the product page, "Suitable for brand" shows which brands a battery is made for. Also look at Bicycle battery Sparta and Batteries for Batavus bicycles.

If Koga is listed, also compare the position, the voltage and the plug, and ideally the part number. Not sure? Ask us before you order.

Usually your current charger, as long as the plug stays the same. Each system has its own chargers: for ION, for example, we have the PMU3 charger with a 4-pin plug, and for Bosch original Bosch chargers.

Never use a charger just because the plug fits: also check that the voltage matches your battery.

Is the item in stock, and do you order and pay before 14:00 on a working day? Then it leaves the same day. Orders that come in later or at the weekend are shipped on the next working day. You always see the shipping costs at checkout; see our Shipping and returns page for the rates.

You can't order an out-of-stock item straight away. On the product page, enter your email address and click "Keep me informed", adding a question if you like. We'll then let you know whether and when we can deliver it, and at what price.

You can return it within 30 days, even if you've already tried it. Returns from the Netherlands and Belgium are free; from other countries you pay the return shipping, unless we made a mistake. The item must be undamaged and come back in its original box. Email your order number to info@azparts.nl and within 1 working day you'll receive a return label (Netherlands and Belgium) or the instructions for your return. Our technicians check the item on arrival; after that we refund you.

Charge your battery at room temperature, between 10 and 25 °C, and never below 0 or above 45 °C. If you don't ride much, charge it at least once a month: a battery that runs completely flat can be damaged beyond repair. So never store it empty either, for example over the winter, and keep it out of strong sun and freezing cold.

Never put it in household waste: that's not allowed, and a damaged lithium-ion battery can cause a fire. Hand it in at your local recycling centre or at a bike shop that takes part in a battery collection scheme (in the Netherlands: Stibat).
