Battery Choice (Read 1501 times)

kdemery TR1 Board Senior Member Posts: 397 Gender: Bike: TR1 & Vincent Rapide	Battery Choice 30.04.20 at 13:09:58 Hello All I need a new battery. My Yuasa batteries only seem to last one winter! I have checked through the previous forum entries and the recommended battery seems to be the Hawker PC535. But, I have checked out the 535 and the terminals appear to be the wrong way around. Plus the battery is slightly too tall for the existing holder. These two batteries appear to be the correct size (slightly smaller and will fit) and have the terminals orientated the right way around. PC370 15AH & PC545 12AH. Does anyone have experience of these batteries? Regards Kevin PS I do not want a lipo battery.

Then I changed the rectifier, an the Problem was gone. Jürgen

kdemery TR1 Board Senior Member Posts: 397 Gender: Bike: TR1 & Vincent Rapide	Re: Battery Choice Reply #6 - 05.05.20 at 16:56:11 I just came across something which may be relevant. I have a GPS bracket fitted on my bike. It comes complete with a power leads that runs back to the battery. Close to the battery on the very same cable is a voltage convertor. I read that the voltage convertor consumes power even when the GPS is not connected or switched on. My GPS is a bike specific unit made by Garmin. Does anyone know if these voltage convertors do consume power whilst not switched on? Kevin

Works well. 25 amp/h and it has posts on both sides of the battery (2x+, 2x-) It was fitted with a pathetic 12 amp/h unit before. Ref the GPS mount I have a Montana with an AMPS mount. No worries about a parasitic drain. Search 'tinternet for parasitic drains. Loads of hits to choose from.
