Weize YTX9-BS Battery Features and Specifications
Weize YTX9-BS battery is a motorcycle/Powersports battery featuring physical dimensions of (L x W x H) 5.91 x 3.43 x 4.25 inches (~15 x 8.7 x 10.8 cm) and the weight of 6.16 pounds (~2.79 kg).
As its label suggests, the Weize YTX9-BS battery belongs to the YTX9-BS motorcycle/Powersports battery group.
Weize YTX9-BS battery features a nominal voltage of 12 volts and a nominal capacity of 8.0 Ah.
Despite very compact dimensions, the Weize YTX9-BS battery features a CCA (Cold Cranking Amps) rating of 135 Amps, which is a good value for a YTX9-BS AGM battery.
Note: AGM YTX9-BS batteries average a CCA rating of 120-135 Amps, although there are some models featuring a CCA rating of up to 180 Amps.
Like all YTX9-BS batteries, the Weize YTX9-BS battery also features nuts&bolt battery terminals with the positive terminal on the left side of the battery, when viewed from the front.
Weize YTX9-BS battery is a factory-activated battery, it is a sealed, maintenance-free, spill-proof battery that can operate in almost any position - it can operate properly even when tilted on the side 90°.
Unlike many other starting batteries, the Weize YTX9-BS battery also tolerates cycling applications well, although the manufacturer doesn't specify the exact supported number of charging/discharging cycles according to the Depth of Discharge (DoD%).
Note: Weize YTX9-BS battery is by default cranking/starting battery and it should be used as such. AGM batteries are more tolerant to cycle use than wet/flooded batteries, but if You need a good battery for cycling applications, go for a deep cycle AGM/Lithium battery.
How To Charge Weize YTX9-BS Battery
When the battery is part of a motorcycle's or similar electric system, let the onboard alternator keep the battery fully charged.
However, if the battery is discharged for whatever reason and must be recharged in the garage/workshop, it is good to know that the recommended charging current is 0.8 Amps (0.1C) using a smart/intelligent AGM battery charger.
Personally, any advanced AGM battery charger in the 0.75-1.0 Amps range will do just fine.
Such battery chargers analyze the battery first and then adjust the charging cycle according to the battery capacity.
Also, due to the negative temperature coefficient of the lead-acid batteries in general, an AGM battery charger with a temperature probe/correction is highly recommended.
A good advanced AGM battery charger will, after fully recharging the battery, switch to the maintenance mode, and keep the battery fully charged which is very important when the battery is being stored for a longer period of time.
What Kills a Powersports/Motorcycle Battery?
Powersport/motorcycle batteries can last for years to come when they are being used as cranking batteries for lawn tractors that are stored in garages, away from the summer heat and winter cold.
For short, the biggest killers of Powersports/motorcycle batteries are vibrations, mechanical impacts, heat, cold, improper charging, partial state of charge operation, etc.
Weize YTX9-BS battery is a sturdy and durable battery, resistant to vibrations and mechanical impacts, tolerant to charging and discharging conditions - for short, use it, but don't abuse it (too much) and it will last and serve You reliably.
Long Story Short: Weize YTX9-BS battery is one of the most popular YTX9-BS batteries on the market - there are YTX9-BS batteries that are lighter, that feature a higher CCA rating, that are cheaper, and similar, but this is a well-designed battery without any major flaws.
It can be used as a starting battery in motorcycles, ATVs, snowmobiles, power generators, marine applications, etc. Also, it can be even used for deep discharge applications, but that is not what this battery is primarily designed for.
