Frequently Asked Questions
(FAQs)
The AB177G (12V 170AH) provides around 10 to 12 hours of backup under a typical household load of 5-6 LED lights, two ceiling fans, and a television. For lighter usage under 100W, backup time can exceed 12 hours on a single full charge. Running heavy appliances like refrigerators, air coolers, or electric irons will reduce backup time, so such loads should be limited to preserve the battery’s discharge cycle health.
Under a typical inverter charge current (about 12–15A), the AB177G takes roughly 11–13 hours to recharge fully from near-empty condition. If the inverter can provide 20A or higher recharge capacity, recharge time drops to about 8–9 hours. In Nepal, where grid power often returns by morning after sudden power grid failure a standard charging setup will fully recharge and recover the AB177G by morning.
