Appendix I Battery Series and Parallel Connection Operating Recommendation
1)
This operating recommendation is suitable for HR1234W battery, equals or lesser than 36 series connection, then 1-6 bank
in parallel, with backup time between 20mins to more than 100mins.
2)
Before battery installation, recommended to perform battery measurement on each individual battery. Due to large number
of batteries in series, the whole set of battery performance will be affected even with only one battery having abnormalities.
Voltage measurement standard recommendation as below:

3)
Battery should be operating with suitable sizing, design, and capacity matching the usage of the equipment. Battery
operating temperature should be 25°C ± 5°C, in float charge. Battery lifespan will be shorten by 50% by every increment
of 8-10°C above 25°C.
4)
HR battery design to be used as standby battery, not recommended to be used in frequent blackout area, a place with
weekly blackout is considered to be a frequent blackout area. Battery will go into frequent charge and discharge cycle,
might cause battery unable to be fully charge.
5)
Ensure that interconnect cable between batteries having adequate current rating, and same resistance between each bank of
batteries in parallel. This is to prevent unbalance charging current to each bank of battery due to resistance differences.
6)
If installed battery is not to be used immediately, recommended to perform charging every 3 months, in float charge for at
least 24 hours. After full charged, suggested to disconnect battery set with UPS, to prevent unintended battery discharge.
7)
It is not recommended to mix install battery of different batch, however it is practically difficult to achieve. Suggested that
the battery in same bank must be same batch. Replacement of battery can be done within 3 months of operating time, new
battery must be fully charge before replacement.
8)
If operating time is within 3 months, the battery replacement can be 1 to 1 in exchange. However if operating time is more
than 3 months, recommended to replace the whole bank of battery. The replacement battery must be fully charged before
replacement, the battery voltage must be measured and recorded. The whole battery set must be balanced charge once after
replacement.
9)
Recommended to perform balanced charge to operating battery set every 6 months, with individual voltage of 14.4V-
14.7V (12V battery), charge for 10-12 hours. Monitor battery temperature during charging, if battery temperature rises
higher than 50°C, the charging should be stop immediately.
10)
After battery set go through discharge, they should be charged back immediately, to prevent sulfation formed on battery.
