ATV Batteries Questions

I had a problem with batteries going dead until I put a battery disconnect switch in..the quad is only used in hunting season ,but I fire it up and run it until it comes up to temperature about once a month.
 
Both my furs have the batteries under the back left corner just inside
the by the tire on the frame.
Frick'n oaribble spot for a battery.
Went to P/A and bought a couple two wire plugs.
Wired in place with the end tied to the rear rack.
The other end to the trickler.
Plug the two ends together and plug the trickler into the wall.
Shazzzam, charging.

Note: the positive side on the quad is the un-exposed one so no
chance of it shorting out.
 
I disconnect the battery for winter storage, remove it from the quad and set it on a wood block. In the spring I put it on a charger for a few hours and it's good to go.

A good quality battery and charger are your friends.
Batteries for vehicles are like ammunition is for guns... they are consumables.
Every couple years drop a couple hundred on routine maintenance on your atv , sxs or quad and it will not leave you stranded.

If your battery is allowed to get any moisture and dirt across the top, it will slowly discharge the battery.
Keep it clean and dry.
I've shown this to farmers on tractor batteries with a voltmeter.
Hook the voltmeter to either terminal, and drag the other lead through the crud. Usually it's less than a volt, (ideally, zero) but I have seen 3 volts on one tractor.
 
I ordered a battery from canadasmotorcycle.ca just two days ago for a steal of a deal Honda 1986 trx350 fourtrax I bought last saturday, YTX14H-BS AGM battery $125.
They sell Yuasa batteries, free shipping. You cannot go wrong with a brand stamped Yuasa battery.
Canadian tire's powersport batteries are Yuasa, but not made to the same level as a brand stamped Yuasa, the Yuasa has about 20% more CCA than the can tire battery.
 
x2, they claim setting a battery on concrete isn't good. Anybody got an explanation ?

That only applies if you're using ancient batteries with wood/glass or rubber cases. With the wood/glass cases the moisture could cause the wood to swell which could cause the glass to crack and with the rubber cases the moisture could allow a tiny amount of current to flow through the case and cause slow discharge.

Anyone who tells you a modern battery will be drained or damaged by storing it on a concrete floor hasn't a clue what they're talking about.
 
I have a CTEK 3300 battery tender which keeps the battery charge and de-sulfured. It comes with two different cable ends. When I had a motorcycle I put the end with the rings on the battery full time and charge it right in bike. I have since used it to charge car batteries and to keep my SLA batteries for the fish finder and for my tin tippy lights topped up in the winter.

Also, buy a quality battery like a Yuasa. They are more money but you get what you pay for in life, especially with batteries.
 
The site "battery university" has a series of well written articles on how lead-acid cells age, and how to get the best life out of them.

Summary: Avoid deep charge cycles. Keep it fully charged. Avoid long-term overcharging and mechanical abuse.

But getting full charge without over charge is a bit of a tradeoff.

It is simple (cheap) to build a charger that will keep a battery fully charged, if you're willing to accept over charging.

It is more difficult (expensive) to build a charger which keeps a battery fully charged without over charging it at room temperature.

It is really challenging to build a charger which keeps a battery fully charged without over charging it when not near room temperature if the charger does not have a way to measure and compensate for the temperature of the battery.

Since you're likely not going to be using a charger with a temperature probe, you'll have better success if you keep the battery near room temperature. The charger will still not be able to compensate for battery temperature, but a least the assumptions it makes won't be too badly wrong.

Then you can either use a cheap charger and turn it on for a few hours every couple of weeks (which I'd forget to do, of course), or get a fancy one and leave it plugged in.

Worst case would be to leave it hooked to a charger outdoors for months, or to let it fully discharge and sit.
