friend of mine has a SIP vape fitted and their speedo, he also runs a sat nav occasionally.he wants to fit a small battery , to charge from the DC trickle charge facility. What size battery would you recommend ?

5-7amp alarm battery is fine and compact

Yuasa have a really good specification pdf on their website. It has sizes, shapes, voltage, amp-hour and even the position of the terminals.

Very helpful.

thanks , info passed on.

Very helpful.

Also, bike batteries have proper screw terminals rather the spade connectors used on alarm batteries which in my experience develope high resistance over time.

Any battery will benefit from some grease on the terminals. Don't worry too much about phrases like 'dielectric grease', almost all greases are dielectric, but it doesn't matter if it is or isn't. The important thing is that it stops corrosion.

True, but the problem I find is that the male and female connector contact surfaces wear enough to cause high resistace. This might be (in my case) due to the batteries on both my scoots being in a box near the rear wheel.
