As the post title says.
I last charged the Samsung 36V 21Ah battery for my ebike back in March 2022 but due to illness haven't been able to ride and it totally slipped my mind. Then today reading about increasing incidents of fires caused by dendrite build up EV car batteries I suddenly remembered about the ebike battery.
Four of the five lights on the battery illuminate when I press the test button so it appears still to be charged. However the sticker says that the battery should be charged every 2 months if left unused – obviously I haven't been doing this. The bike (and battery) was bought new in February 2021, very light use only (about 70 miles on the clock), and has been stored indoors under the stairs since March so should not have experienced very cold or hot temperatures.
What is the likelihood that the battery is perfectly safe to use and charge? Or should I be very worried?
