hello ,
on my 55,19s i am thinking of fitting a 6 volt battery without the plastic box. i already have one of the plastic boxs you put a battery in. but the lid doesn,t seem to secure. it makes for a loose fitting battery.
i would like one similar to the one in the link below, just wondering if it would be ok, power wise.

Overcharging
of batteries is an issue for early alternator systems with crude regulation, but surely this is not an issue with dynamo bikes? I have a 6V 6Ah lead acid battery on my bike, inside a replica rubber case. It's what my bike had when I got it in 1983 (still a Yuasa, but not the same one). No boiling issues so far.
I have a halogen 6V 36W headlamp and LED other bulbs. Above idle speed, the ammeter registers a balance whether lights are on or not.
BTW a friend is making me a special driver for a 6A LED headlamp bulb, originally 12V input. The LED actually takes 9V, so requires a step-down driver. He is making me a step-up driver so I can run it off 6V with my standard Lucas CVC unit.

For what it's worth: 8Ah…
For what it's worth: 8Ah works fine for me. I've got two 6V gel-type lead batteries coupled in parallel and they've been great for the last two years. Strapped them together with rings of old inner tube and fitted them with a rubber band to keep them firmly in place. I guess it acts as a very thin, makeshift anti-vibration battery box.
I've got an original magdyno, original regulator and original bulb lights, no LED's. Vision at night is poor at best though, which is also original... :)

Having a plastic box severely limits the Ahr you can get on your bike. I do NOT like it. The 8Ahr in this link looks fine but who are Shield? Time and again bikers (yes you lot) say 'I only want a small battery'-load of rot. the larger Ahr flooded lead acid was allowed to regulate by fuming a bit. Small batteries, certainly sealed (alarm) batteries cannot, they will overcharge and fail.
