How to swap the insides of two batteries (Shimano BT-E8035-L and BT-8035)

[Future Paper]

Hello, I ordered a Shimano BT-8035-L long version BT-8035 battery for my Merida E One Sixty 10k (2019) and received the wrong size. They are identical to each other. Is it possible to rearrange all the insides from the new elongated battery to the old one (BT-8035) ? and how safe is it?

You can slide the insides out by taking the end caps off. Think its 4 torx screws from memory.

I haven't seen inside the L version, but would guess its the same with a spacer. Only way to find out is to take it apart and have a look!

Out of interest, what are you planning on doing with the old internals?

I guess.

you don't mention what bike you have. With certain bikes the internal battery mount just needs the battery mounting plate rearranged in order to fit the two different length shimano internal batteries
