Exposure charging weirdness

I recently bought a Maxx D Mk13

Just topping it up for tomorrow nights ride and it started at 97% - probably didn't really need topping up to be fair

It's now still charging 20 mins later and it says 91% - *edit now 92%

Sure it did this last time, but eventually got to 100%.

Anyone else seen anything similar?

Might just leave it as I know batteries don't like having the last few % forced in

My Race never gets to 100%, just hovers at 95%, so I'm not sure if this isn’t just an Exposure thing

Are you switching on the charger before connecting it to the light?

In this instance, no. Why?

I think Exposure lights charge to 95% then its goes to a trickle charge for the last 5% which takes an age

Don't they go into trickle charge once the battery reaches a certain % (90?) - to protect the battery.

I get that - will protect the battery.

Just strange how it charged at 97% for a good few minutes, then when I looked again, had dropped to 91%

I've got a couple of things that ask you to make sure the charger is plugged in and awake before connecting it to the device/battery.
(I also have a couple that say the opposite!)

leave it plugged in for over 24 hours. It will error and effectively reset the battery.

I'll check the instructions next time to be sure

After contacting Exposure about worse than advertised battery life, I was told, by them, to switch the charger on before connecting it to the light. That was a few years ago and I've continued to do so.

^^^ I was told that too, though it was perhaps by you ! 🙂

Maybe the battery warmed up a bit and therefore had a greater capacity, so could take on a bit more charge..?

That would probably drop the readout in the way described.  My Race does this sometimes and also normally sticks at about 95-97%.

My Toro does the same - gets to about 97% then trickle charges the rest of the way.
Turning it on shows the full 100% though and the times shown for light remaining are accurate.

I had some weirdness too. Exposure told me to use the charging plug rather than the cable for best results. Not sure it made too much difference tbh.

Yeah, that's a possibility.

Fully charged at 100% now anyways.

Cheers all

I have to occasionally do this with a Sixpack that doesn't get used very often.

It apparently re calibrates and balances the cells.

I also think you need to turn the charger on before plugging it in or it changes what program you have it set to.

charge it until you get a code appearing instead of 100%

I have the same issue with my Maxx-d, plug it in to charge and it decreases. I just unplug it all and ensure the socket is on before I plug in the charging cable.

I've had my maxx D go initially from about 70% (by just looking on the light before charging) then once charging slowly drops to ~60% but then go back up to 100% after a few hours
