Battery for R75/5

Post by slyngej »

Which battery would you recommend for a R75/5.
I guess much have happened since the 70s which my manual is from.
Gel, lead-acid...?? and how many Ah would you recommend?

I use the Panasonic

It comes in the thin size the fits (important) my swb 1970 r75/5.
No complaints at all.

After seeing the posts, I checked again and this is an AGM after all.

AGM's are much less finicky than gels. Thus, I either go with the cheapest wet cell I can find, or I go with an Odyssey. I've given up on gels.

For something prone to falling over (GS's, for instance), I never go wet cell. My Oilhead has an Odyssey. My Suzuki DRZ400 has a lithium - which also is super light, but I wouldn't spend for one of those for a normal street bike. Where I live there's a long winter, so the fact that both lithium's and AGM's will better stand sitting without being used for long periods is important to me. If I lived somewhere with a year-long riding season, I'd be a lot more likely to run a conventional wet-cell in the Oilhead. My /2 held a wet-cell, but that was mostly because it just seemed wrong to put anything more modern in there. ;)

When thinking about batteries and charging systems it's worthwhile to think about the consumption side of the equation.

An early airhead with a worn and Weak starter motor will suck the life out of most batteries on a cold start and the battery won't have time to recover if used on short trips. it can worthwhile to think about a new starter that will kick the engine into life much more quickly and really reduce drain on the battery at startup.
