I have a 2002 Honda Rancher. I think the battery is original. It is a sealed type battery. When charged, it only holds 12.25 Volts. Time for replacement?
What kind of batteries are these?
What is the best way to charge them?

 

you can get them from an auto parts store or pretty much any atv dealership.

 

i always use yuasa batteries. they are a sealed type. they come with the electrolite out of them. just have to snap the electrolite canister on the battery and it fills by its self. watch your eyes when doing this. than just charge it at low amp over night and you are ready to go.

probaby the best batteries you can buy.

 

You can usually get them from Walmart too.
When it comes to ATVs and such I generally go with the cheapest I can find.
Considering that it's more of a utility as opposed to a racer I see no need for a sealed battery.

 

That is a AGM battery, if you have to fill it with electrolyte it is not sealed. Filled batteries are called flooded, there is nothing wrong with them, but they can leak if the atv is rolled over or anytime the battery is upside down.

well technically it is a sealed battery. once you add the electrolite and pop on the seal there is no service afterwards.

they just don't ship em with the elctrolite in them.

i've had the same batter on my honda foreman for 5 years now with no issues. yuasa is the most popular here in toronto.

 

Yuasa is a great battery we sell some here, but all our sealed batteries come filled and charged ready to go. There is no way to even get into them without wrecking them. AGM batteries are safe to ship anywhere.

 

I'd also go AGM, Yuasa or another quality brand.

In addition to not needing to be filled, AGM's resist freezing to lower temps, won't leak even if the case is broken or upside down, they resist vibration better, and generally last longer.

The stock battery on most any ATV these days is an AGM type.


I'd also suggest snagging a Battery Tender Jr. Sitting in a partly charged state for long periods of time (like quads tend to do), can shorten the life of a battery, and the little intelligent charger will solve that problem. They also make a water proof model if you need to use it outdoors.

 

Part of my work to get "Pinky" (my scooter) road ready was to replace the battery. The original was a Yuasa 3 amp battery, that I killed by accidently leaving the ignition on for 5 months, oops. I replaced it with a 4 amp Yuasa (same physical size) for $45. Bought it from a Motorcycle/ATV shop.

I did have to fill it with the acid electrolyte too. Here are several precautions you should take.

• Wear eye protection, this is Sulfuric acid we are dealing with here.
• Wear rubber gloves if you have them too. Chemical burns suck.

 

Yuasa have proven to be the most reliable for me...
