Li-poly batteries normally have a lifetime of around 400-500 recharge cycles up to 1,000 plus... at upwards of 3 hours reading per dat, I recharge around 7-10 days so even taking the most conservative view, 400 recharges for 7 days reading each gives 2800 days before failure which is around 7+ years. I think ordering 2-3 spares is a bit of overkill especially as you will need to remember to charge them somehow every few months or they'll die anyway... Li-poly batteries are very good bar the occasional failure but if it's faulty then it won't normally even last the warranty period. Paranoia doesn't mean they aren't out to get you but don't take it too far...
