Drops nearly 8 lbs of weight while delivering 400 cold cranking amps for instant ignition — at 3.31 lbs versus the Weize YTX14-BS at 9.6 lbs.

The TYKOOL LFP14-BS is a lithium (LiFePO4) battery built for adventure riders who want to reduce weight at the top of the bike. At just 3.31 lbs, it weighs 3.31 lbs compared to the Weize YTX14-BS at 9.6 lbs. That weight savings lowers the bike’s center of gravity, making cornering and off-road handling feel more agile.

An integrated LCD voltage display lets you check the battery’s health at a touch, so you can monitor the electrical system while touring. Its IP66 waterproof casing (fully protected against powerful water jets) protects the cells during river crossings or heavy rain. The catch: you must confirm your bike’s charging system stays under 15.0V, because lithium cells need a stabilized voltage to avoid damage.

A sealed lead-acid brute with 310 CCA that replaces YTX20L-BS and fits big twins and jet skis — stronger cranking than the TYKOOL lithium (310 CCA vs 400 CCA) though heavier.

The Deka ETX20L is a straightforward, no-nonsense sealed battery for riders who need raw cranking power without lithium complexity. Those 310 CCA (cold cranking amps) matter for larger engines, cold starts, or vehicles with high parasitic draws like jet skis with stereo systems.

Ships fully charged and ready to install — no acid filling required. The 18Ah capacity (amp-hours — how long it delivers current, roughly 18 amps for one hour) supports long cranking sessions without voltage sag. Buyers report it fits 2000 Harley Fat Boys and 97 Sportsters correctly, and one buyer installed it in an airplane with a first-crank start. The trade-off is weight: as a sealed lead-acid unit, it is heavier than AGM or lithium options, so you will feel it on a sport bike where weight distribution matters.

The same battery many Suzuki and Honda dealers install — one buyer mentioned theirs lasted 8 years on a Suzuki.

The Yuasa YTX7L-BS is a bottle-supplied AGM battery, meaning it ships dry with a separate container of electrolyte (acid) that you add yourself. This design keeps the battery fresh on the shelf indefinitely because no chemical reaction has started. Once filled, the lead-calcium chemistry is engineered to hold its specific gravity more than three times longer than conventional lead-antimony batteries.

Its dimensions are 5.5 inches deep, 7 inches wide, and 5.25 inches tall, giving it a larger footprint than many equivalent-capacity batteries. The trade-off comes when you compare it to the Weize YTX14-BS, which measures 3.42 inches deep vs 5.5 inches for the Yuasa — that is a 61% difference in depth. Buyers consistently report that this Yuasa is the genuine OEM fit for models like the Honda CRF250L and Suzuki DRZ400, and one owner reported it lasted a full 8 years on a Suzuki. The catch is that initial filling requires care — the included acid bottle’s cap doubles as the battery cover, and you need M5 bolts and rectangular nuts that are not included in the box.

A lithium battery with a built-in jump-start button that saves you when the battery is too drained to crank — far handier than the TYKOOL’s voltage display alone.

The Anti-Gravity AG-ATZ-10-RS uses “Re-Start” technology — a dedicated reserve of power that you activate by pressing a button on the battery case. If you drain the main charge by leaving the headlights on or an alarm running, you press the button and the battery delivers enough power to start the bike without needing jumper cables or a separate jump pack. One owner noted that after a month of sitting, his FZ07 was completely dead, but the re-start feature got him running again.

At just 1.18 kg (about 2.6 lbs), it is significantly lighter than the AGM batteries in this list. It has posts on both sides, making it versatile for routing positive and negative cables however your bike requires. A reviewer riding a 2024 KTM 1290 Super Adventure R confirmed it fit perfectly with no software adjustments needed. The main downsides are its premium price and the fact that while the re-start works, you still need to recharge the battery fully after using it — it is not a permanent fix for a deeply discharged cell.

An AGM battery that gives you 200 cold cranking amps at a price that undercuts most name brands by a wide margin — for riders who want drop-in reliability without spending lithium money.

The Weize YTX14-BS is a sealed AGM (absorbed glass mat) battery that comes fully charged and ready to install. It is designed to replace YTX14-BS, ETX14, and CTX14-BS types across Honda, Kawasaki, Suzuki, Yamaha ATVs and motorcycles. The battery delivers 200 CCA and has 12Ah capacity at the 10-hour discharge rate, which is enough to reliably start a 750cc to 1200cc engine in moderate climates.

At 9.6 pounds, it is heavier than the Yuasa YTX9-BS (4 lbs) featured next, but that weight comes from the AGM plates that give it strong cranking power. The dimensions are 5.9 inches wide by 3.42 inches deep by 5.7 inches tall, which is more compact than the Yuasa YTX7L-BS (5.5 inches deep). One customer observed the battery died after 60 days, but the seller immediately sent a replacement — a sign of responsive customer service. Another owner left the bike neglected all winter, drained the battery completely, gave it a short charge, and it went strong again, so it handles deep discharge better than expected.

A compact 4-pound AGM battery that fits tight motorcycle trays — 4 lbs versus the Weize YTX14-BS at 9.6 lbs while packing OEM-level performance.

The Yuasa YTX9-BS is the same Advanced lead-calcium AGM design as its larger sibling above, but in a smaller package — 3.44 inches deep by 6 inches wide by 4.19 inches tall. At just 4 pounds, it is lighter than the Weize YTX14-BS (9.6 lbs) while still providing maintenance-free, spill-proof power. It ships dry with an acid bottle (BS = bottle supplied), meaning you fill it yourself before the first use, which guarantees the cells are fresh.

Buyers on sport bikes like the Kawasaki ZX-6R report strong cranking in both hot and cold weather, and one KTM 390 Adventure owner called it the “gold standard” for AGM batteries. However, one reviewer experienced a failure at 3 months where the battery would not hold a charge, and had to deal with a slow replacement process. That is a reminder that even reputable brands can have a bad unit slip through, though the general consensus across reviews is very positive for consistent starts.

An entry-level sealed AGM battery that fits Recons and smaller ATVs at roughly one-third the local shop price — the lowest upfront cost on this list by far.

The ExpertPower YTX12-BS is a sealed lead-acid AGM battery that comes fully charged and requires no acid handling or water top-ups. Its dimensions are 3.43 inches deep by 5.91 inches wide by 5.12 inches tall, and it is designed to fit vehicles using the YTX12-BS, GTX12-BS, or UTX12-BS group sizes. It replaces batteries in the Honda TRX250 Recon and other small to mid-size ATVs and motorcycles.

The biggest selling point is the price: one reviewer noted they paid about one-third of what the local shop wanted, and the battery arrived the next day. It is factory-activated, so you can install it immediately. However, there is a notable caution in the reviews — one buyer mentioned the battery failed from day one, requiring daily charging and jump starts, and only resolved the issue by switching brands. That means while the value is strong, you might get a dud, and there is no mention of a generous replacement policy like the Weize has.
