Yuasa GTZ8V vs YTZ8V Battery

[smrbike]

I have a 2016 PCX150 and and replaced the HONDA OEM battery with a GTZ8V and it has been gtreat, but due to COVID,.... it has set too much and not charged properly. I tried to purchase a replacement GTZ8v that i paid $52 (USD) in 2018, but it appears to no longer be available in the US. The sister YUASA company has the same battery with the first letter in the part number changed from G to Y. It is $110-150 if purchased through a YUASA dealer. The Honda dealers apparently are still able to get the "G" version. It is $78-$88 deppending on where you get it Honda or Revzilla. Any feedback/suggestions appreciated.

Update:
Contacted YUASA and they no longer distribute the GT version of this battery. Only the Y version is available for purchase. Honda still uses/sells this part using the GTZ8V YUASA part number so it may possibly be sitting on the shelf getting OLD. Summit Racing sells the YTZ8V version for the least amount $107 (free S&H).

Finally found answer!!

The GTZ8V is a Sealed WET Cell Battery. It has been discontinued and replaced with the YTZ8V that is AGM!!! It should last 2-3 times as long as the wet cell version. The few GTZ8V batteries I have found must be left over stock and OLD. Do Not Purchase. I will be getting the new AGM version.

From Yuasa:

Yuasa launch new Yamaha & Honda OEM replacement battery
Yuasa, the worldwide leader in motorcycle batteries, has introduced the new YTZ8V battery to its world-famous YTZ range. The absorbed glass mat (AGM) battery is designed to replace the Original Equipment (OE) battery in the 2015 Yamaha YZF-R3 sportbike and 2015 Honda PCX150 scooter.

The YTZ8V provides a significant increase in power despite its small, lightweight size. It delivers an impressive 120 Cold Cranking Amps (CCA) despite measuring just 113mm x 70mm x 130mm and weighing 2.7 kg

The high performance YTZ battery is 12 volts, rated at 7.4 AH. It is supplied factory activated and ready to fit. In addition to the YZF-R3 and PCX150 the YTZ8V also has a number of other applications as either the standard battery or a higher performance upgrade option.

The AGM technology used in the YTZ8V is an advanced battery design that eliminates water loss. Because of its lead calcium design, an AGM battery will hold its specific gravity more than three times longer than conventional lead antimony types. This means much longer periods between charges when the battery is used less frequently, such as winter storage.

The Yuasa YTZ8V AGM battery is shipped factory activated, which means it does not require filling before installation. An extensive activation process ensures complete absorption of the electrolyte so no liquid acid is contained within the battery. This process allows these batteries to be shipped from the factory ready to install. Also, since the electrolyte is absorbed in the special plates and separators, there is no need to worry about leaks on valuable vehicle parts and accessories.

As the world’s leading battery brand and OE supplier to all of the top ¬motorcycle manufacturers, every Yuasa battery provides the same high performance, quality and reliability as the bike’s original.

Not often acknowledged, only Yuasa and GS produce genuine YTX, YTZ and GYZ high-performance batteries, these codes have become generic throughout the industry but are, in fact, registered to GS Yuasa.
