Gazelle E-Bike Battery

Behind the connections (which can be unscrewed) are lids of plastic.

Unfortunately the lids are glued to the front and the end.
Even with a sharp knife you can not loosen the glue.

The only possibility is the battery on the sides cut open.
I use a small circular saw, the cutting depth is approx. 3 mm.

If one cuts at the places as seen in the pictures, one does not damage the batteries.

Here are a few pictures where you can see how much work such a small battery can make

At the end you will find 40 cells with about 2200mAh

How do you get the nikkel strip of the cells? I keep putting holes in the cells when I pull them off. It depends on the packs but some are very hard. It looks like the strip is thicker in some packs. It can get pretty frustrating sometimes.

Jonas - if the nickel strip is too hard to remove, just snip it back with a sharp pair of cutters. Leaving a little bit of nickel behind will be fine, just take care, it can be sharp when handling the cells.

I think it was a gold battery. The bronze battery is much shorter and Silver has less batteries

I think it a Bronze one. I have one glued like the Dretje, which has bronze listed on the label.

All others Gazelle batteries are easier to open, for example:

They contain different battery packs (stored inside the container) including one which contained flat cells.

regarding the nickel strips , i grind the welds with a dremel first and then cut them away
if there are some leftovers on the battery i also grind this away with the dremel.

regarding those cells in the last photo on the left in the yelow container from the gazelle are potential very dangerous in my opinion
becouse the bms does not look to all cells as in the packs on the right.
i also have some of that type and i am surprised that overall the cells are in fine condition , but are low in capp 1,6Ah (new )

Hey,

I opened a few of these batteries in the past.
No need for electric tools, way to dangerous.
Remove both ends like shown in the picture. Remove Glue, silicon with a cutter or utility knife.

To remove the battery from the enclosure take a piece of wood, put in in the enclosure and tap it gentle bur firmly with a hammer. The whole pack will slide out of the enclosure.

Good luck.

This will not Work for the newer packs.
These have a very hard epoxy and some strange black grease.
The best way is cutting as described.

Hi

image_srhlsg.jpg


the small cases in the picture are bronze and no name, the bigger ones are silver, gold or platinum.

image_gpphtx.jpg

on the label it says how many batteries are installed.


The old batteries were simply glued with silicone, the new ones are now glued with epoxy adhesive and waterproof.

Here is a photo of the first battery from Gazelle. They did not have a name like Bronze Silver or anything like that ....

Each cell has 1500mAH. The BMS is not even waterproof.

I also have some experience opening these. I'm also using a cutter to make an incission and than open up the case.

From my experience this is only the case when it say's "Made in EU"
