YT type has air-absorb structure, which can absorb hydrogen by negative plates when charging, then reverse to electrolyte.
You don't need to check the liquid level and refill water.
By the way, in order to avoid damage from internal air-pressure, which is produced by charging, we have setted safety valves.
Safety valves can release gas when air-pressure being high.
electrolyte is conserved in glass mat, don't need to worry about spilling through when engaging
Glass mat was made of glass fiber web stacks, then sticked into piece shape by adhesive.
Glass mat has acid-resist, drug-resist, electric-resist, electrolyte dredge, and low electric
conductivity features, which can prevent short of positive/negative plates touch, drop
of active material from plates, and keep the distance between each plate.
High start performance
High-performed specific alloy plates and low-resistance glass mat can keep engine start performance well in cold climates.
Fast electrolyte filling design
The filling design can easily puncture the seal of electrolyte canister well in cold climates.
And there has two vent holes surrounded for air release when filling electrolyte.
Make it simple for electrolyte filling.
※Please read the filling guide on electrolyte canister.
YT type has high performance lead-calcium alloy plates, which has much lower self-discharge than Standard type.
※Recharge battery regularly when not use for a long time recommanded.
There have explosion proof stones on both sides of vent holes, which can restrict the path of flame or spark inside the battery that cause probable explosion.
