One of the best value ATV batteries you can buy, the Expert Power ETX9-BS
is an excellent combination of affordability and performance.
Don’t let its small size fool you – this is a powerful, hardworking piece of electrical equipment. In fact, it uses its compactness as an advantage, as you can fit this battery in a host of other equipment – from solar panels, generators, and motorcycles.
As an ATV battery, this one covers all of the basics. We hooked it up as a replacement battery for our aging Honda 300EX, and it fired up as if it was brand new, with a constant voltage exceeding the 12-volt minimum. Note that we’ve replaced it countless of times with stock batteries over the years, and it lasted us a few years at best. We reckon the ETX9-BS
will best that record!
Self-discharge rate during periods of non-use is impressive at only a 3% loss. Expect your ATV to start right up even when left unused during the cold winter months or for very long periods, for example.
Construction is definitely durable, and AGM technology ensures there would be no hazardous leaks, even when the battery itself is damaged.
The only minor drawback is the “just enough” CCA rating of 105. Well, it’s a drawback depending on where you live and how overpowered your ATV is. Colder temperatures or lots of extra add-ons might give this one a hard time, but folks living in warmer weather need not worry about it too much.
Also, a thing to note is that since it’s compact, it can be a bit smaller than some stock batteries. If this is the case for you, simply wedge in some fillers for a snug fit. At its worst, it’s just a very minor inconvenience.
Overall, the ETX9-BS
is an excellent pick if you want a basic ATV battery that performs exceedingly well. With a price that is hard to beat in its class, it’s a great return on your money.
