January 17, 20251 yr I spend a lot of time, up to 6 months, away from Thailand and usually leave my bike with a friend. Most times they take the battery off the bike. The last time which included the flooding the battery was dead. I bought a high quality FB battery. I watched a YouTube video about how to take care of batteries which said I should keep it on a trickle charger. I might be away for 10 months this time and leave the bike under a covered section at my condo. Is that safe? Should I leave battery at another friends where it would be charged outdoors in their car port?
January 17, 20251 yr I do it with my auto in the US when I'm here. Works well. Do you have any place near you bike to plug the charger into?
January 17, 20251 yr Author Not if I leave it at the condo. Are you talking about leaving it on charge whilst connected to the bike? I was thinking of taking to my friend that lives 15 minutes walk and leaving it outside in her car port. If I left it on charge in my condo with no one there I was thinking it could be a fire risk. Also I looked quite a lot on AliExpress and particularly at the brands with the most sales but still there were no clear choices on which charge to buy. This is on of those "bigger" brands.

I've used a CTEK trick trickle-charger for a good number of years now... I have 'bike-dash-cams' hard wired in and there is mild battery drain which isn't an issue when using the bike regularly, but when I'm away for more than a month it can drain the batter - the CTEK trickle charger takes care of this and ensures the bike remains in 'hassle free ready to use condition' any time I want. https://www.lazada.co.th/tag/battery-charger-ctek/
January 17, 20251 yr Author This was the one I thought I'd embeded in my post but I just read embeded links don't work anymore on this forum. www.aliexpress.com/item/1005007002770297.html Ctek was the other brand I looked at.
January 17, 20251 yr I would only buy a good quality charger to leave unattended for months unless you remove the battery. If the battery cracks or blows, the mess the acid will make is a nightmare.

Unless I was jump-charging I wouldn’t, but people do. You could also just disconnect the ground for an overnight change. If I wanted to leave a battery trickling for six months, I take it out and put it in a bucket or whatnot.
January 17, 20251 yr Author https://s.lazada.co.th/s.tzgk7 The one Ctek recommends for batteries stored for a long time. I'm just wondering what the difference is between it and a 1000 Bt charger from AliExpress.

If you use a proper charger, yes you can. To the OP, I use (and have for years) used an OptiMate 3...but if you're going to be away for months I would either disconnect the battery (just the earth wire), or remove it completely and put in on charge when you return.
January 30, 20251 yr Just disconnect the battery when you leave, most of the time when back it still has a little to start the bike. Otherwise take the battery to any corner shop nearby, or with your own charger, let it charge for 30min, it will have enough to start the bike, and then go for an hour ride and all be okay..., we have been doing it for over 15 years, and so far so good...!
