Winter Battery Care Reminder

[Wiltshire Warrior]

Last night dipped to 1 Deg C in Southern England, so time to store your batteries indoors - mine are in the wardrobe at 50%

good advice

As long as your batteries are at storage voltage (30-50%) and not actually below freezing there should be no negative impact to storing in a shed or garage. However the performance of lithium cells (an all batteries for that matter) is diminished at low temperatures, so make sure you let them come up to room temp before charging and (if you have an external mount battery and live in a cold place) consider a battery "jacket" to keep it a few degrees warmer on the trail.

There are some good neoprene battery jackets out there for the external Bosch and Shimano batteries

See this storing battery's at a certain % is a little bit of a annoyance to me. As alot of my rides are random. I finish work early and I'll jump on the bike or it will be a nice morning at 6am on a Saturday and I'll get up early and go out for a few hours. I don't really plan my rides in such a way I know when to have them fully charhed. So I just charge mine after most rides back to full. But there never stood for more than a couple days. Just hope I'm not ruining the baytery...

Unless you are draining the pack fully every time you are probably best to store it at ~70% rather than 100% charge. If you do that the internal damage due to dendrite growth primarily caused by storage at elevated state of charge (SOC) is reduced, but you can still do the same rides every few days.

Where can I get one for Shimano? Cheers.

Seen any reasonably priced ones? All the ones I've seen have been about 35 quid

Yes was ready to remove mine and store and charge indoors when its cold

Only this kind:

Its for the e6000 battery though, but prob works on e8000 - TBH i think one could pretty easily knock up a homemade solution

That's £32 delivered anyway. Yeah. an old wet suit leg/arm and 5 minutes with a pair of scissors would probably do the job. Think I might even still have some of the kids old ones stashed somewhere.

If you (or someone you know) is handy with a sewing machine an old wetsuit, some thread and an hour or so may well do the job...

 

[Kaelidoz]

Just asked my wife to sew one for me... she's too busy .

Yup going to grab that 30€ Fahrer at my local shop.

An hour?
I was more thinking just cut the arm of the suit to roughly the correct length of the battery and pop the battery inside it..
No sewing.

@Doomanic's suggestion is better
