HEALTH BATTERY DROPPED FROM 98 TO 93% IN FEWS DAY

[f1s0ciety]

Hi guys, I'm a bit worried because in checking the health of the battery I noticed that it dropped by 5% in a few days... thats crazy because in 1 year have just dropped 2%... and now in fews days... 5%
what do you advise me to do? did any of you happen?

I have a different bike and different manufacturer, but same thing Has happened to me. I have a BESV bike with a Brose motor. Their is a corresponding app that monitors motor and battery health. My first battery died at 78 cycles. That battery was replaced. The 2nd battery died at twelve cycles. Each time the battery health never achieved 100 percent, although they were new and always kept in ideal conditions. The battery health would fluctuate in the low 90 percent range. Nonetheless.....both batteries just stopped working. I recieved 2 brand new batteries after the first 2 died.......both batteries arrived with a Heath status in the mid 90’s. I assumed they just needed to be balanced. That’s not the case.They have now both settled in at a battery health of 93 percent. One battery has 53 charge cycles and the other 6 charge cycles.

Hi f1, I have a 2019 Explore E+3 and check the battery statistics every once in a while. I have seen the Battery Health drop when I have been doing partial charges up to 80%. After a couple of cycles letting the battery go down to 20% and then charging completely to 100% the Battery Health statistics go back up to 98%+. My bike is 2.5 years old and I haven't noticed any battery degradation and the Battery Health is currently ranging from 92-98%.

I also have the 19 explore e3, battery fluctuate between 92 and 99

48 cycles so far

I think the best solution is leave the battery after the ride out with 30% or more without recharge immediately and just recharge completely when it is used again . Right ?

I just got a 2021 Roam e+, so different battery and charger than the one on the Explore. I decided to check the battery health after my first charge up, and was suprised to see it was only 94%. I called the dealer and asked about this, and he said Giant told him it's normal for a new bike/battery to read below 100%. He said it shouldn't drop below 90% - if it does let him know. okayyyy.

I'm going to watch it carefully since it's so new. Also, was wondering whether anyone has any tips on discharging the battery without the fancy charger. My charger has no buttons or guages - just an LED indicator light. The manual said something about fully discharging the battery every 90 days, and then charging it back up to 100% in order to ensure long life. Is there a way to discharge the battery fully without riding it until it dies??

UPDATE: before we travelled for TK holiday week I charged battery up to 60% and brought it inside the house. The garage is uninsulated and nighttime temps are in the high 40s, so figured it would be happier inside.

Yesterday I put it on and did a nice 10-15 mile ride, mixed terrain and some steep single track climbs. When I got back I was at about 25% remaining, and battery health was 99%. That was a happy surprise. So maybe it just needed some conditioning. It's showing only two charge cycles.

I have over 3k km on my 19 explore 3, the battery health on the original battery that came with the bike is around 95 to 97%. I bought a 500 capacity last year from a guy who got his bike stolen. the battery health on that battery is between 96 to 98, it only has 10 cycles.

i Heard heat is primary killer for battery health, I usually don’t recharge the bike until 2-3 hrs after each ride just so that the battery gets to cool down a little before I charge it.

whatever the case, I think this bike will last me a long time between the 2 batteries, hopefully the Motor holds up.
