Is my battery on it's way out.....

[mobile mouse]

I'm a Mr..


I have a battery tester  so will check the voltage.
My journey to work is 8miles each way and it's made up of 1/3 is 30mph. 1/3 is 50mph and 1/3 is 70+mph.


It has just dawned on me that I have been using my heated grips recently with it being cold.
And the bike does have a Meta alarm fitted, I forgot to mention this, sorry.


I wonder if the extra drain on the battery has had a greater drain on the battery than expected.






What I find strange is that the chatter under the seat I believe is the starter relay opening/closing, went away after raising the revs.
Lower the revs and it came back. Is that the alternator charging the battery and cancelling out the low battery voltage temporary.


If I find the voltage down then I presume that I will need a new battery but will need to keep the bike on the optimate each night to keep the battery fully topped up.


I don't want to get too caught up in the charge state of the battery if I have knackered a cell then I will have to cough up for a new battery.


What would members recommend stick with the gel type or are the new type of batteries that much better.
cheers,
