So I have had an ongoing issue my original battery in my 700 grizzly kept dying so I replaced it with a gel battery.. later I found my winch was shorting out an that's what was killing my battery.. so my new gel battery keeps dying I ride the grizzly 3 times a week 30 mins at a time . With engine running volt meter reads 14.25v which is awesome so I know at is charging the battery. I took the gel battery back to the battery outlet the owner charged it an tested it everything was fine.. so I put it back in my quad and everything was good for months.. then I left my key on overnight it.. so I charged it immediately in the morning but now the battery will only last 2 or 3 starts an I have to hookup the charger again.. is the a reason why it won't just charge off the atvs electrical system? I also put my old battery in for a few weeks and it works perfectly fine . Any help is appreciated guys

With theach gel battery in the atv not running it is 12.2v when I hit start it drops to 6-8v .. I have trickle charged the gel battery in the past is that the right thing to do

It sounds like your gel battery is either discharged or toast. Charging them with the wrong charger or at the wrong rate may permanently damage them even if the battery is new.
If you have any sort of warranty left take it in for evaluation. For your next battery buy an AGM , better suited for ATV use.

12.2 volts is bad. If your only getting that after charging the battery, then your battery is toast and needs replacement. Leaving the key on overnight and completely draining it could have damaged a cell.
Rollin above also got it correct. You can't use just any charger on a gel battery.

I've gone through numerous batteries over the years with my ATV and PWC (both expensive and cheap brands of batteries) and the one thing I've finally learned is that unless you start it every day, they all require a battery tender. Battery tender Jr is the best imo...

ONE EASY SOLUTION .... BATTERYMINDER....!!!
I run my Grizz only a few times a year but it always starts up as long as I am plugged in....had a battery tender but it seemed to always ruin my battery instead of maintaining it. The Batteryminder has been a revelation .... My truck sat last winter for 7 months with one connected to it and it fired right up once it was time to get back on the road.
