It’s cold outside. The electricity goes off again, and you’re waiting for the UPS to turn on. But this time, the heater fan barely runs for 10 minutes. Frustrating, isn’t it?
That’s your battery getting weak, just when you need it the most. In Pakistan, many people think battery problems happen only in summer because of the heat. But actually, winter is even harder for weak batteries, cold weather slows charging, and longer power cuts drain backup faster.
Let’s talk about 5 clear signs your battery is dying this winter, and how you can fix the problem before the next load shedding hits.
1. The Backup Time Is Getting Shorter
If your UPS that once powered lights and fans for hours now barely lasts 20–30 minutes, that’s the first red flag.
Why this happens in winter:
→ Batteries lose efficiency in cold temperatures.
→ Old cells can’t hold charge properly.
→ You’re using extra load like heaters, blankets, and geysers.
What you can do: Reduce heavy load items, but if your battery is already old, that won’t help much. The smarter move is to upgrade to a lithium battery, it gives long, stable backup even in cold weather
2. Your Battery Takes Forever to Charge
Winter slows everything including your old lead-acid battery. If it takes the whole day to charge but drains in an hour, your battery is losing capacity.
Why this happens:
→ Thickened electrolyte in cold weather
→ Old battery cells
→ Overuse during long outages
What you can do: Give your battery enough rest between charges, but long term, shift to ENERBYTE lithium batteries. They charge 5x faster and maintain full power even in cold conditions.
3. You Keep Checking or Adding Water
Even in winter, many homes still say, “Battery ka pani check kar lo!”. With old lead-acid batteries, water level drops due to chemical reaction and without it, battery backup disappears.
Why this happens:
Lead-acid batteries need regular water top-ups for proper performance. But in Pakistan’s dry winter air, water evaporates faster than you’d expect.
What you can do: Stop worrying about filling or maintaining. Switch to ENERBYTE lithium batteries. They’re sealed, water-free, and 100% maintenance-free.
4. Battery Gets Hot or Smells Strange (Even in Cold Weather)
Even though it’s winter, if your battery is getting hot or giving off a burning smell, that’s a serious warning.
Why this happens:
→ Overcharging overnight
→ Damaged internal plates
→ Weak UPS settings
What you can do: Turn off your UPS immediately and let it cool down. Avoid using old or leaking batteries in closed rooms, they release harmful gases. For your safety, replace it with ENERBYTE lithium batteries that stay cool, clean, and safe in every season.
5. The UPS Keeps Beeping or Shutting Off at Night
If your UPS starts beeping again and again during the night, even when there’s power left, your battery voltage is unstable.
Why this happens:
→ Battery is too old
→ Internal resistance increased
→ UPS can’t detect proper voltage
What you can do: Don’t ignore those beeps! It’s your battery’s way of saying “I’m tired.” Replacing it early prevents your UPS or inverter from getting damaged.
