Pitiful cells, but what's the alternative?
on March 3, 2014
Charge does not hold for long... Usually just after 20-30 seconds of using our Shark on a carpet, the LED turns red. The charge holds maybe for another 15min max, than sharks stops operating completely with all LED's flashing. After 2 days of using this new battery replacement, I couldn't even start my Shark in "turbo" mode on a carpet at all. It choked instantly! Only when switched down to the medium sweep speed, our Shark operates for some 15min on a full charge or this "wonderful battery."
All this happens despite the fact that I opened, cleaned (e.g. from stubborn long hair) and lubricated all moving parts for a minimum friction.
The problem here is not only with the batteries. It is unfortunate that Shark forces users to get these prefabricated cell assemblies, instead of using one of the customary size rechargeables (e.g. "C" size), what would make Shark users very happy and very independent. Shark does not provide good quality replacement packs at it seems, we rely of these dubious sources of lowest quality batteries. The obvious result of this situation is that we look for a different brand replacement.
