a good battery

[john21z]

hi can any one tell me the make of a good battery. has any one tried a amg batt or gel

Bosch (if you can get them). Other than that I tend to use Varta or Banner for lead acid batteries.

For gel batteries, I use Dynavolt. You can get them on eBay now for as little as £20! Obviously dependant on the model. I've just bought one for the GPX, equivalent to the YB14AL-2, for £37.49

hi are the motobatt batterys worth the extra 20 quid or is it all bull about gel batterys

[thunderace]

Gel batteries are extremely good, I'm in the process of switching over now the prices have dropped (lots of bikes you see).

They don't suffer from cold like lead acid, they have a higher cranking capacity compared to lead acid, they don't suffer anywhere near as badly from deep discharge and they weigh a lot less.

I offer the comments below only to further the discussion on "a good battery". Although this info is from wikipedia, there were references for a number of the disadvantages however there were none for the advantages. Anyone have references for the advantages.

Claimed Advantages

Very little venting, usable in confined areas with limited ventilation
Fluid retention – un-spillable
Water conservation – never requires addition of water
Acid encapsulation in the matting
Availability of UL, DOT, CE, Coast Guard, and Mil-Spec approved types
Vibration resistance due to the sandwich construction.

Disadvantages

Expense gel batteries as much as five times greater.
Less reliable than flooded lead acid
Longer recharge time than flooded lead-acid
"Sealed" batteries cannot tolerate overcharging: overcharging leads to premature failure.
Unable to use hydrometer to diagnose improper charging.
Unable to replenish electrolyte with water.
Shorter useful life.

I don't see the point in using anything other than the standard battery, just a decent make one like Varta.

After adding the acid, let it sit for 30 minutes and fully charge it with a slow-rate motorcycle charger and you should be good to go.

Providing your electrical system is in good order and you keep the battery charged up (use an optimate / slow-rate charger etc when not using the bike for longer than a week or two) you shouldn't have any problems.

I have a Varta in my NC24 which I brought in 2008 and it still works perfectly.

Over in my country, the best battery to use is a Yuasa battery. works great with my nc35. never had any problems with it.
