Phoenix EXT-135 UPS Battery 100Ah Price in Pakistan

The Phoenix EXT-135 is a 12V flooded lead-acid box battery from the EXT Series, rated at 100Ah with 15 plates. On paper it matches the EXT-130 exactly, and it may be the newer name for that model. Being a flat-plate flooded battery, the EXT-135 costs less per Ah than a tubular one and is happiest with outages of one to three hours. For homes with steady two-hour load shedding, a flat-plate 100Ah battery such as the EXT-135 is a good value pick.

On 300W of fans, lights and a router, the EXT-135 lasts about 1 hour 40 minutes, using 50% usable depth and 85% inverter efficiency. Add an inverter fridge to reach about 600W and the EXT-135 drops to about 50 minutes. Size-wise, the EXT-135 fits a common 12V home UPS of about 1 kVA on its own, or a 24V inverter when used as a pair. If you charge the EXT-135 from panels, use a proper charge controller set for lead-acid, not lithium.

Every few weeks, look at the EXT-135's water level and top up with distilled water; do not overfill. Clean the EXT-135's terminals now and then and keep its vent caps tight. See how to check battery water (How to Check Battery Water and Top It Up Safely) for a step-by-step method that works for the EXT-135.

Warranty terms for the EXT-135 are not in our data, so ask before ordering and keep the card. The real life of the EXT-135 is set by your use: heat, deep drains and low water are what kill lead-acid batteries.

Against its siblings: If a shop has both the EXT-130 and EXT-135, the specs we have are the same, so pick the one with the fresher manufacturing date. If you want a little more, the EXT-140 adds 5Ah and two plates (105Ah, 17 plates). For a bigger jump, the UGS-155 and UGS-160 give 115Ah with 17 plates. Compared with a lithium battery, the EXT-135 costs less upfront but you can only use about half its 100Ah each day; read lithium vs tubular (Lithium vs Tubular Battery: Which Is Better for Solar?). Bottom line on the EXT-135: buy it for this (popular search model, easy to find in shops), and keep this in mind (no warranty period in our data; ask before ordering).
