The AA batteries that come with Dinotte

The instructions say that an overnight charge is required. Well, I just got the delivery and I'd like to use them on my commute home.

Is "only" a four hour charge going to negatively affect battery life or charge duration? Are they being conditioned for capacity or something on the first charge?

Thanks!

It'll be fine. Just charge them overnight at the next opporutnity.

Enjoy the light!

They probably recommend a charge because they are NiMh batteries - meaning they lose some of their charge as shelf life increases. If they have been sitting around unused for a couple months they could be at 50% or less of their original capacity. The recommendation for a charge before initial use would seem to be certain that they will achieve their rated capacity for endurance and not strand a rider in the dark after 20 minutes.

Eneloop technology (hybrid batteries), although posessing a lesser total capacity (2000 vs 2700mAh), hold their charge much better than standard NiMh batteries. Hence the term precharged when purchasing them. You could put Eneloops directly into your device without an initial charge.

By the way, I am not familiar with what type of batteries Dinotte uses and am merely commenting on what I believe the issue is.

The batteries are 2600mah, so even a slow charger should be able to get them fully charged in, say, three hours, yeah?

Sounds like caution on the part of Dinotte and not necessarily a functionality thing?

Thanks all.

Depends on the charger's output. Some take 7 hours and some take 15 minutes. Three hours on a middle of the road charger would seem to allow you to get an hour or so in without issue - possibly much more.

Also, the batteries don't have memory, so partially charging them will not hurt them at all. In fact I believe it takes a couple cycles of charging/discharging before they will be at full capacity.

You could always carry a spare set of AA alkaline batteries in an emergency. I think under Dinotte's FAQ they state that ordinary alkalines could get you by in a pinch for up to 30 minutes.

Good luck!
