Home UPS-Flooded Flat Plate Normal-STANQUEEN Range

Features

Thick Plates for Long Life		Enhanced Service life
Through partition inter-cell welding ensures better Voltage profile on discharge		Abuse ResistantElectrolyte level indicator for easy top-up.
Steady Discharge during power cuts		High Rate Discharge performance
		User Friendly

Advantages

Better thermal management

Special polyethylene separator.

Customized exclusively for inverters

Better Reliability

Expected life–2 years plus – under arduous conditions.

More than 20% extra electrolyte (in SQ500+) which means lesser topping-up frequency and an unhindered performance

Easy maintenance

Initial Charging Instructions

Filling in specific gravity 1.220±0.005 at 27°C

In case the temperature exceeds 50⁰C, adequate rest to be given till the electrolyte temperature comes to ambient temp. and charging to be continued

Rest period 12 hrs.

Condition of fully charged –

Minimum Ah input as per above chart.

3 consecutive hourly readings of specific gravity and voltage become constant

In order to reduce the charging time, the initial charging current would be as specified till 2.36 Volts/Cell followed by finishing current as specified till 2.75 Volts/Cell.

	Top of charge voltage will be around 16.2V – 16.5V
	All cells should gas freely.
	Minimum Ah has been given

However in both cases, Minimum Ah input to be given. Under no circumstances, battery temperature should exceed 50°C.

Specific gravity at fully charged condition – 1.250±0.005 at 27°C

Normal Recharging Instructions

Battery should be re-charged through an Inverter at constant potential mode of 14.4V with limited current as specified. After battery potential reaches 14.4V, the battery should continue in float charge mode at constant potential of 13.5V.

Statutory Notice

All batteries contain lead, which is harmful for humans and environment. As per statutory requirements, the used battery must be returned to the authorized dealer, manufacturer or at the designated collection centers.
