Battery YUASA or Deka

Energizer or Yuasa are good quality from my experience. I’ve had an energizer for 5 years now still running and my last yuasa ran great till I drained it to zero doing stupid.

I had battery problems and got a YUASA and had no issue since so I think they’re a decent brand (highly recommended by people).

I run a Yuasa in my 114 Streetbob. Best battery on the market.

Second the Yuasa recommendation. Best battery I’ve had. Bought last one on Amazon. I like that the acid hasn’t been added yet so you know it’s fresh.

I fully trust Yuasa. They're just excellent quality.

Left one uncharged for a whole winter fired right up.

UPdate - new battery and bluetooth 12v monitor installed last Monday night, all good since then including one day with 40 miles of driving and recharging in weather well below freezing (16 to 28 F), but I happen to be mostly driving other cars the rest of the time since.

FYI, altho I ordered from Remy, the sticker on the battery I received says [Deka Intimidator EHP](https://remybattery.com/batteries/brand/deka-intimidator-batteries.html?srsltid=AfmBOorxsFi7eoMbizQPDMsF1q-32WuvMxLPyiLSgftX8ExWmqHWSfq4). IDK if there's any functional difference - it seems to have the exact same terminal connections as the OEM BMW battery it replaced.

Also FWIW, despite no indicator on the shipping box for 'this side up' and it clearly getting Ace-Ventura'd around by FedEx, it did not leak or show any signs of damage inside the shipping box. It was well padded with foam made to fit the battery and fill the entire shipping box. So far I'm happy and the car seems to be too.

OEM for Harley. I've replaced several with an average lifespan of 5 yrs at 20%+ cheaper than Harley branded

As a harley tech I see more aftermarket batteries fail then I see oem ones fail. There are a few good aftermarkets like DEKA but for the most part aftermarket batteries seem to fail quicker then oem.

Just use a Deka ETX20L. I think they're 15 pounds or so and they're cheap and widely available. Mine seem to last about 2-3 years, although they usually die from me forgetting to turn the headlights off. I was able to recharge my last one using a wall charger and I squeezed another 6 months out of it before finally replacing it.

Yuasa used to make great batteries, would get ten years out of a battery ('91 R100GS) outside w/o a battery tender. Not any more, the last two were good for six or seven months
