A battery question

My '73 850 uses points and the stock charging system with a gel cell battery. Where I keep the bike, there is no electricity so I can't trickle the battery. I do have a trickle pigtail in case I can use it. Would it work to connect my gel cell battery via the pigtail to a car type hot start (enclosed battery with leads that sometimes has a light and small compressor) just while I kick the bike over or would this do harm to my gel cell and/or any part of the charging system? I ask especially since it seems these gel cells are sensitive to how they are charged. When I do trickle the battery, I do use the correct type of charger (Battery Tender). Thanks for any thoughts on this.

I'm sure somebody will tell you some advice about your battery, if it were me I'd check the webiste of the battery maker for instructions on charging. Where your bike is do you have any chance of running boat solar charging or a wind unit?

I had a small solar setup at one point but they don't seem to last. I guess my basic question is: can I use a car hot start to hot start my gel cell in my Commando or is it too strong for the motorcycle size gel cell?

I don't know about using the car battery, it might work.

Another option might be a to set up a quick-disconnect system and remove the battery and move it somewhere you can charge it.

How frequently is the bike ridden?

Connecting an extra 12V supply (pos. to pos and neg.to neg.) from a battery pack or from an additional battery as a booster should be OK.

Although if the battery is being allowed to discharge to a level that the engine won't start without help then it's not doing the battery any good.

I know AGM batteries can be left for several months and they still hold their charge, maybe gel ones do? Certainly ordinary wet lead-acid batteries do not, so should be charged up every 4 to 6 weeks or so.
