Why warranty length matters
Tubular inverter battery warranty has two components: a flat-replacement period and a pro-rata period. Exide IT500 ships 48 months flat + 18 months pro-rata = 66 months total. V-Guard VT 200 ships 36 months flat + 24 months pro-rata = 60 months. The flat-replacement period is what really matters — that is the time you can claim a free swap. After flat, you pay a pro-rated amount.
