Martel BP-33 Rechargeable Battery Kit

The Martel BetaGauge 330 rechargeable battery pack kit includes an 8-cell Ni-MH battery pack, cell-con smart battery charger and Beta330 battery patch cord. The rechargeable battery has a 2.7Ah rating and can perform better with the pump running compared to regular Alkaline batteries which are about 2.0Ah. This Martel rechargeable battery has a high self-discharge rate, so batteries that have not been used in 30 days or more may need to be charged before use.
